Highlights¶
Periprosthetic Joint Infection¶
PJI diagnostics and management dominate this month's hip literature. Enhanced research culture methods detect more anaerobes than standard clinical workflows, potentially altering antibiotic planning [1]. Deep bone sampling yields higher culture positivity than soft tissue in one-stage exchange [100], while intraoperative synovial calprotectin point-of-care testing shows promise for rapid diagnosis [97]. A systematic review supports intra-articular antibiotic delivery combined with one-stage revision [25], and one-stage exchange appears feasible even in Candida PJI [103]. PJI is the leading indication associated with in-hospital death after revision arthroplasty [68,73], and Delphi consensus statements now standardize periprosthetic surgical irrigation [92,93].
Hip Arthroscopy and Preservation¶
Hip preservation research spans surgical technique, healing, and patient selection. Capsular repair improves 12-month healing, with healing correlating with better early PROMs [7], and quantitative MRI parameters of unhealed capsule associate with persistent symptoms [86]. Labral repair outperforms debridement in non-athletic FAI patients [10], while labral reconstruction offers moderate return-to-sport rates [60] and segmental peroneus longus allograft techniques are described [11]. Biomechanical work shows labral augmentation and remplissage restore distraction stability after over-resection [8]. Long-term data show femoral head osteochondral lesions predict lower survivorship [9], adolescents with borderline dysplasia fare reasonably [12], and older patients improve but report lower symptom acceptance [20,37]. A sham-controlled RCT pilot adds equipoise evidence [77], and central sensitization symptoms associate with worse PROs [83].
Revision THA Reconstruction¶
Complex revision hip arthroplasty is well represented. Novel bicolumnar fixation with primary cup implantation addresses pelvic discontinuity [4], and a next-generation constrained liner shows favourable mid-term outcomes in high-risk instability [17]. Porous tantalum components demonstrate re-revision risk stratified by defect severity and fixation [90], custom triflange components show 94% survivorship for advanced defects [91], and the Kerboull cross-plate's evolution and indications are reviewed [26]. A comprehensive review revisits acetabular bone defect management [84]. Femoral-side options include de-escalation with shortened rectangular-taper stems [33], modular tapered stems for Vancouver B2/B3 fractures [70], and cancellous impaction grafting in Crowe III/IV dysplasia [76]. Referral patterns to tertiary revision centers are characterized [89].
Hip Fracture Care¶
Geriatric hip fracture research emphasizes timeliness and perioperative optimization. Capacity-related surgical delay is associated with increased mortality [39], and a framework addresses antithrombotic management to avoid further delays [53]. General anaesthesia carries higher morbidity and mortality in frail patients undergoing fixation [79]. Predictors of early medical complications after hemiarthroplasty include comorbidity burden and fracture pattern [43], and dislocation after hemiarthroplasty is scoped comprehensively [45]. Comparative fixation data show the femoral neck system versus cannulated screws and DHS in transcervical fractures [72], while finite element studies optimise intramedullary nail length [54] and both-column screw constructs [50]. International consensus on operative versus non-operative management was achieved [56], hospital harm risk factors were identified [49], and in-hospital mobilization practice remains suboptimal [58].
Technology and Precision in THA¶
Technology adoption and surgical precision feature prominently. Robot-assisted THA improves implant positioning and biomechanical restoration, though clinical benefit translation remains uncertain [44], and robotic or navigated techniques did not improve five-year implant-related complications in osteonecrosis THA [38]. Robotic assistance improves acetabular positioning accuracy in revision [21]. Learning curve studies show implant placement precision during early direct anterior experience [3] and characterize the anterolateral supine approach [61]. Patient-specific instrumentation improves resurfacing accuracy [88], and computer-assisted navigation aids hip arthroscopy portal and anchor placement [19]. Broach holder offset increases femoral loading during preparation [46], and cemented stem volume impacts failure risk [69,82].
Arthroplasty Outcomes and Pathways¶
Health-services and recovery research rounds out the digest. Day-case arthroplasty implementation succeeds more often in logistically separated arthroplasty centers [5], and machine learning identifies perioperative factors associated with same-day discharge in a non-selective ERAS pathway [31]. Psychological factors consistently influence outcomes: the FEAR framework organizes fear-related barriers [65], depression and anxiety predict function after arthroplasty [81], and preoperative SSRI use shows dose-dependent complication risk [85]. Preoperative pain intensity predicts achieving MCID for function [28]. Dual-mobility cups reduce 10-year revision risk versus standard cups [101], and single-stage bilateral THA appears safe in patients 70 and older [66]. Digital education and exercise therapy improve physical activity trajectories in hip OA [32], and sports resumption guidance is surveyed in Brazil [99].
Articles by Theme¶
Periprosthetic Joint Infection (9)¶
1. Visperas A, Lu Q, Lehman B, et al. Research culture methods detect more anaerobes compared to conventional clinical workflows in periprosthetic joint infection: a pilot study of 14 cases. Archives of Orthopaedic and Trauma Surgery 2026. doi:10.1007/s00402-026-06550-7
In this pilot study, intraoperative synovial fluid, periprosthetic tissue, and implant swabs from 13 PJI patients were processed using both standard clinical culture workflows and optimised research protocols. Research culture methods detected more anaerobes than conventional workflows, though both identified primary organisms. These additional microbial findings may inform antibiotic treatment planning and suggest value in enhanced culture techniques for culture-challenging PJI cases.
25. Chang X, Luk MH, Cheung A, et al. Intra-articular antibiotic delivery combined with one-stage revision for periprosthetic joint infection: a systematic review. Arthroplasty 2026. doi:10.1186/s42836-026-00440-4
A systematic review of ten studies evaluated intra-articular antibiotic delivery combined with one-stage revision for periprosthetic joint infection, synthesizing techniques, safety, and clinical outcomes with at least 12 months of follow-up. The combined strategy showed satisfactory infection control and acceptable safety. This approach may offer a viable single-procedure option for PJI, though higher-quality evidence is needed to confirm its role.
68. Yao W, Chen S, Chen X, et al. Early Readmission and Mortality Across Periprosthetic Joint Infection Trajectories After Revision Arthroplasty. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.09.051
This retrospective study of 1,228 revision hip or knee arthroplasties (2008-2024) categorized patients into four trajectory groups based on index revision indication and subsequent post-revision periprosthetic joint infection (PJI) status, examining 90-day readmission and all-cause mortality. Post-revision PJI occurred in 3.5% of patients, and those developing PJI had markedly higher 90-day readmission rates (14.0%) than those who remained infection-free. The findings suggest early readmission may flag patients at risk of recurrent infection, supporting trajectory-based risk stratification and closer follow-up after revision for PJI.
73. Rusche A, Roth A, Pempe C. Periprosthetic joint infection as the leading indication associated with in-hospital death after revision hip and knee arthroplasty: a ten-year single-centre retrospective cohort study of 103 in-hospital deaths among 2495 patients. Journal of Orthopaedic Surgery and Research 2026. doi:10.1186/s13018-026-07259-4
A ten-year single-centre retrospective cohort study reviewed 103 in-hospital deaths among 2495 patients undergoing revision hip or knee arthroplasty, characterising circumstances, causes, and treatment strategies by revision indication (periprosthetic joint infection, periprosthetic fracture, other). In-hospital mortality was 4.1%, with periprosthetic joint infection identified as the leading indication associated with death, often involving septic shock and ICU admission in elderly patients. The findings highlight the need for heightened perioperative vigilance and risk stratification, particularly for patients revised for infection.
92. Aggarwal VK, Alvand A, de Andrés-Torán A, et al. Delphi Consensus on Periprosthetic Surgical Irrigation: Irrigation Solution Selection and Comparative Effectiveness. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.10.017
A Delphi workgroup of experts developed consensus statements on the selection of irrigation solutions for periprosthetic joint surgery, using a structured iterative voting process to address solution type and comparative effectiveness. The consensus provides evidence-informed guidance where randomised data are limited. Surgeons can use these recommendations to standardize irrigation practices and reduce unwarranted variation in solution selection.
93. Aggarwal VK, Alvand A, de Andrés-Torán A, et al. Delphi Consensus on Periprosthetic Surgical Irrigation: Technique and Intraoperative Administration. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.10.018
A companion Delphi consensus from the same workgroup addressed irrigation technique and intraoperative administration in periprosthetic joint surgery, achieving expert agreement on procedural parameters. This establishes standardised technical guidance in an area previously lacking consensus. The statements can inform operative protocols and quality benchmarks for irrigation delivery during arthroplasty and infection management.
97. Giatroudakis K, Iliopoulos E, Kateros K, et al. Prospective Evaluation of an Intraoperative Synovial Calprotectin Point-of-Care Lateral Flow Test for Periprosthetic Joint Infection in Hip and Knee Revisions. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.10.026
In a prospective cohort of 80 hip and knee revision arthroplasties, synovial fluid was aspirated intraoperatively and tested fresh with a dedicated calprotectin point-of-care lateral flow assay against the 2018 ICM criteria for periprosthetic joint infection. Median calprotectin was markedly higher in infected than aseptic cases (138 vs 7 mg/L in THA), supporting diagnostic discrimination at a ≥50 mg/L threshold. The test offers a rapid intraoperative POC tool to help confirm or exclude PJI during revision surgery.
100. Russo A, Zanna L, Luo TD, et al. Optimizing Intraoperative Tissue Sampling in Hip and Knee Periprosthetic Joint Infection: Deep Bone Provides Higher Culture Yield in One-Stage Exchange. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.10.031
In 255 one-stage exchanges for hip and knee PJI, culture positivity of intraoperative specimens was compared across deep bone, superficial bone, and soft tissue sampling sites using generalized estimating equations adjusted for patient factors. Deep bone sampling yielded the highest culture positivity in both hips (80.8%) and knees (80.5%), with significantly higher adjusted odds of positive cultures than other sites. Surgeons should prioritise deep bone sampling to maximise pathogen identification during one-stage exchange for PJI.
103. Klein S, Letscher-Bru V, Rondé-Oustau C, et al. One-Stage Exchange in Candida spp. Periprosthetic Joint Infection: an appropriate solution?. Orthopaedics & Traumatology: Surgery & Research 2026. doi:10.1016/j.otsr.2026.104982
A retrospective single-center study evaluated 16 unselected patients with chronic Candida spp. PJI treated with one-stage exchange and antifungal therapy between 2012 and 2021, with minimum 2-year follow-up and EBJIS criteria for infection. The hypothesis was that outcomes would not differ from two-stage exchange results reported in the literature. If confirmed, one-stage exchange may be a viable alternative to the traditionally advised two-stage approach for Candida PJI.
Hip Arthroscopy and Preservation (12)¶
7. Shen L, Li W, Chen K, et al. Capsular Repair Improves 12‐Month Healing and Favorable Healing Correlates With Better Early Patient‐Reported Outcome Measures in Femoroacetabular Impingement Syndrome Patients Undergoing Hip Arthroscopy. Arthroscopy 2026. doi:10.1002/arj.70694
Patients with femoroacetabular impingement syndrome undergoing hip arthroscopy with interportal capsulotomy were divided into repair and nonrepair groups, with capsular healing assessed on MRI at 6 and 12 months alongside patient-reported outcome measures. Capsular repair improved 12-month capsular healing rates, and favourable healing correlated with better early patient-reported outcomes. These findings support routine capsular repair at hip arthroscopy to promote healing and improve early clinical outcomes.
8. Husemoglu RB, Aydemir S, Akın E, et al. Labral Graft Volume Augmentation and Femoral Remplissage Have Positive Impact on Hip Distraction Stability After Excessive Cam Resection: An Ovine Model. Arthroscopy 2026. doi:10.1002/arj.70679
In this ovine biomechanical study, 48 fresh-frozen hips with a 10% over-resection cam defect at the head-neck junction underwent labral reconstruction at varying graft volumes, femoral remplissage, or combinations, followed by distraction testing to measure suction seal strength. Excessive cam resection significantly reduced hip distraction stability, while 4× labral volume augmentation and combined 2× augmentation with remplissage best restored stability. These results support labral graft volume augmentation and femoral remplissage, alone or combined, to restore distraction stability after excessive cam resection.
9. Perets I, Quesada‐Jimenez R, Barda SR, et al. Femoral Head Osteochondral Lesions Predict Lower Survivorship but Not Inferior Patient‐Reported Outcomes After Hip Arthroscopy at a Minimum 10‐Year Follow‐Up. Arthroscopy 2026. doi:10.1002/arj.70627
In a propensity-matched cohort of 188 patients undergoing hip arthroscopy for FAI and labral tears, those with femoral head osteochondral lesions (Outerbridge ≥2) were compared to matched controls without femoral head damage at minimum 10-year follow-up. Femoral head cartilage lesions predicted lower survivorship (higher conversion to arthroplasty) but did not result in inferior patient-reported outcomes among those retaining their native hip. Clinically, the presence of femoral head chondral damage should inform prognosis and shared decision-making regarding arthroscopy, particularly regarding long-term arthroplasty risk, even when early outcome scores appear favourable.
10. Salem KA, Elsaeed AM, Ganzouri IE, et al. Arthroscopic labral repair versus debridement in non‐athletic patients with femoroacetabular impingement: A prospective randomized study. Knee Surgery, Sports Traumatology, Arthroscopy 2026. doi:10.1002/ksa.70661
In this randomised trial, 60 non-athletic patients with symptomatic FAI were assigned to arthroscopic labral repair or selective labral debridement with concomitant cam/pincer resection. The repair group showed superior Harris Hip Score and HOS-ADL scores at 3 and 6 months, but by 12 months outcomes converged with no significant differences in functional scores or VAS pain, and complication rates were similar. For non-athletic patients, labral debridement may offer comparable mid-term outcomes to repair at one year, potentially avoiding the added cost and complexity of repair in this population.
11. Kody MT, Banffy MB. Segmental Arthroscopic Hip Labral Reconstruction Using a Peroneus Longus Allograft. Arthroscopy Techniques 2026. doi:10.1002/atn2.70375
This technical note describes a segmental arthroscopic hip labral reconstruction technique using a peroneus longus allograft for focal irreparable labral defects, particularly in the revision setting. The approach provides consistent graft sizing, avoids donor-site morbidity, and preserves healthy native labral tissue through a stepwise process of patient selection, portal placement, graft preparation, delivery, and fixation. Segmental reconstruction may restore the suction seal and joint mechanics while avoiding the morbidity of circumferential reconstruction when defects are focal.
12. Nishimura H, Afetse EK, Brown J, et al. Clinical Outcomes of Arthroscopic Femoroacetabular Impingement Surgery for Adolescent Patients With Borderline Hip Dysplasia With a Minimum 5-Year Follow-up. The American Journal of Sports Medicine 2026. doi:10.1177/03635465261491021
This retrospective cohort study compared minimum 5-year outcomes after primary hip arthroscopy in 122 adolescent patients (≤19 years, open proximal femoral physis) with FAI, contrasting those with borderline hip dysplasia (LCEA 18°-25°) against those without (LCEA ≥25°). Patient-reported outcomes including mHHS, HOS-ADL/Sport, SF-12, and WOMAC were compared between groups. The findings help clarify whether arthroscopy alone is appropriate for adolescents with borderline dysplasia and FAI, informing surgical decision-making in this young population.
20. Vega TF, Sparks CA, Casanova F, et al. Patients Aged ≥60 Years Achieve Comparable Improvement but Lower Patient Acceptable Symptom States After Hip Arthroscopy for Femoroacetabular Impingement Syndrome Using Contemporary Techniques: A Propensity Score‐Matched Cohort Study. Arthroscopy 2026. doi:10.1002/arj.70631
A propensity score-matched cohort study compared patients aged ≥60 years with those ≤40 years undergoing contemporary hip arthroscopy for femoroacetabular impingement syndrome with labral repair and capsular closure. Older patients achieved clinical improvement comparable to younger patients across patient-reported outcome measures, but were less likely to reach patient acceptable symptom state thresholds. Hip arthroscopy remains a reasonable option in selected patients over 60, though expectations for acceptable symptom states should be tempered.
37. Vega TF, Pérez Lloveras GO, Thamrongskulsiri N, et al. Hip Arthroscopy in Patients Aged 60 Years or Older Is Associated With Short‐Term Improvement but Variable Arthroplasty Conversion Rates: A Systematic Review. Arthroscopy 2026. doi:10.1002/arj.70615
This systematic review of 7 studies (199 patients, 204 hips) evaluated outcomes of hip arthroscopy in patients aged ≥60 years with femoroacetabular impingement. All studies reported significant short-term improvements in patient-reported outcome measures, but conversion rates to THA varied considerably across studies. Hip arthroscopy can offer benefit in carefully selected older patients, though counseling should acknowledge variable durability and arthroplasty conversion risk.
60. Tao X, Cheong T, Nawabi DH, et al. Labral Reconstruction of the Hip Provides Moderate Return to Sports for the Treatment of Labral Tears: A Systematic Review. Arthroscopy 2026. doi:10.1002/arj.70514
A systematic review of 8 studies (262 patients, mean age 33 years) evaluated return to sport and patient-reported outcomes after hip labral reconstruction for labral tears. Return-to-sport rates ranged from 64% to 88%, with improvements in modified Harris Hip Score, Non-Arthritic Hip Score, Hip Outcome Score, and pain scores. The findings support labral reconstruction as a reasonable salvage option yielding moderate return-to-sport rates, aiding shared decision-making in young active patients.
77. Warholm KM, Hibbert E, Ageberg E, et al. Arthroscopic Surgery Versus Sham Surgery for Femoroacetabular Impingement Syndrome and/or Labral Tears: A Double-Blind Randomized Controlled Pilot Trial (HIPARTI). Orthopaedic Journal of Sports Medicine 2026. doi:10.1177/23259671261453311
In this double-blind randomised controlled pilot trial (HIPARTI), patients with femoroacetabular impingement syndrome and/or labral tears were randomised to arthroscopic surgery or sham surgery, both followed by identical physical therapist-led rehabilitation, with hip-related quality of life (iHOT-33) at 1 year as the primary outcome. The study addresses the scarcity of placebo-controlled surgical trials in this field by controlling for the placebo effects of surgery and anaesthesia. Results will inform the design of a definitive trial and clarify how much of arthroscopy's reported benefit is attributable to the procedure itself.
83. Nojiri S, Saito M, Numajiri S, et al. Central Sensitization-Related Symptoms Are Associated With Worse Patient-Reported Outcomes in Patients With Acetabular Labral Tears: A Cross-Sectional Study. Orthopaedic Journal of Sports Medicine 2026. doi:10.1177/23259671261491000
This cross-sectional study of patients with acetabular labral tears used the 9-item Central Sensitization Inventory (CSI-9) and the 12-item International Hip Outcome Tool (iHOT-12) to assess the relationship between central sensitization symptoms and hip-specific patient-reported outcomes. Higher CSI-9 scores were associated with lower iHOT-12 scores, confirming the hypothesized relationship. Central sensitization should be considered when evaluating patients with labral tears whose symptom burden exceeds their structural pathology, potentially guiding nonoperative or adjunctive management.
86. Li W, Long H, Sun L, et al. Associations Between Unhealed Capsular Quantitative Parameters and Clinical Symptoms After Arthroscopic Surgery in Patients With Femoroacetabular Impingement Syndrome: A Propensity Score–Matched Study. Orthopaedic Journal of Sports Medicine 2026. doi:10.1177/23259671261490200
This propensity score-matched case-control study evaluated quantitative MRI parameters of unhealed hip capsules (length, cross-sectional area, volume) in 72 FAIS patients after arthroscopy without capsular closure, comparing symptomatic and asymptomatic groups. No significant differences were found in unhealed capsule parameters between groups. Capsular healing status after unsutured hip arthroscopy may not be a major determinant of postoperative symptoms, suggesting other factors drive outcomes in FAIS surgery.
Revision THA Reconstruction (10)¶
4. Abul MS, Ağır M, Yılmaz H, et al. Novel bicolumnar fixation with primary cup implantation for pelvic discontinuity in revision hip arthroplasty: a comparative clinical study. Archives of Orthopaedic and Trauma Surgery 2026. doi:10.1007/s00402-026-06424-y
This comparative clinical study evaluated a novel bicolumnar fixation technique with primary cup implantation for managing pelvic discontinuity in revision hip arthroplasty, as an alternative to traditional cage-based reconstruction. The approach aims to restore pelvic continuity and achieve biological fixation rather than relying solely on mechanical fixation. The technique may improve construct stability and reduce implant migration, loosening, and mechanical failure compared with cage-based methods.
17. Khury F, Luebbering B, Ruff G, et al. Patient-specific management in high-risk revision total hip arthroplasty: mid-term outcomes of a next-generation constrained acetabular liner. Archives of Orthopaedic and Trauma Surgery 2026. doi:10.1007/s00402-026-06527-6
A retrospective review of 37 revision total hip arthroplasties with a next-generation constrained acetabular liner, tailored to individual biomechanical deficits, was performed with an average 4.7-year follow-up in a high-risk cohort (70% operated for instability). The study assessed mid-term clinical outcomes and failure modes of this patient-specific constraint strategy. The findings support using tailored constrained liners to address recurrent instability in complex revision settings, though the small, single-center sample warrants caution.
26. Wegrzyn J, Kerboull L, Béjui-Hugues J, et al. The Kerboull cross-plate: from the birth of a concept to the current indications. International Orthopaedics 2026. doi:10.1007/s00264-026-07059-9
This narrative review traces the Kerboull cross-plate from its original conception to current indications in revision total hip arthroplasty for major acetabular bone loss. Finite-element analyses demonstrate a marked load-sharing effect protecting bone graft compared with other reinforcement devices or unprotected cemented cups, and the authors detail surgical technique, refinements in plate positioning, and graft selection principles. The review supports the device's continued use for restoring the hip center of rotation and shielding grafts, with indications tailored to defect type.
33. Fischbacher A, Mahlouly J, Lacheux N, et al. Femoral de-escalation during revision total hip arthroplasty using a rectangular-taper shortened stem. International Orthopaedics 2026. doi:10.1007/s00264-026-07049-x
In 23 revision total hip arthroplasties, a cementless rectangular-taper shortened primary stem with a dual mobility cup was used as a femoral de-escalation strategy. At a mean 48-month follow-up, there were no periprosthetic fractures, mechanical failures, or early loosenings, with good Harris Hip Scores. This suggests that in selected revision patients, preserving femoral bone stock with a shortened primary stem is a viable, safe alternative to long diaphyseal-fixation revision stems.
70. Chaudhry F, Bridger A, Kolhatkar K, et al. Treatment of Vancouver B2 and B3 Periprosthetic Femoral Fractures Using a Modular Tapered Stem: Survivorship and Radiographic Outcomes at Mean 7.8-Year Follow-Up. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.09.044
This retrospective review of 46 patients (mean age 73, mean follow-up 7.6 years) evaluated revision total hip arthroplasty with a modular tapered femoral stem for Vancouver B2 and B3 periprosthetic femoral fractures. Kaplan-Meier survivorship free of all-cause revision was 95.1% at 15 years, with four failures reported. The findings support modular tapered stems as a durable fixation strategy for these challenging fractures, with favourable long-term implant survivorship.
76. Kawasaki M, Okura T, Futatsugi R, et al. Autogenous Cancellous Bone Impaction Grafting Is a Viable Technique for Managing Acetabular Bone Defects Observed During Primary Total Hip Arthroplasty in Crowe Types III and IV Hip Dysplasia Cases. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.10.005
This retrospective comparative study compared autogenous cancellous bone impaction grafting (CBIG, n=18) with femoral head structural bone grafting (SBG, n=17) for acetabular defects in Crowe III/IV dysplastic hips undergoing THA, with over 12 years of follow-up. CBIG offered shorter operative times and comparable long-term clinical and radiographic outcomes, with graft remodelling and osteolysis volumes assessed on CT. Cancellous impaction grafting represents a viable, durable alternative to structural grafting for managing acetabular bone deficiency in severe dysplasia.
84. García-Rey E, Lustig S, Karachalios T, et al. Acetabular revision surgery revisited: do changing indications influence bone defect management? A comprehensive review. EFORT Open Reviews 2026. doi:10.1530/eor-2026-0029
This comprehensive review examined how acetabular revision surgery has evolved 25 years after the introduction of highly cross-linked polyethylene, focusing on bone defect management amid changing revision indications. Advanced imaging and 3D planning have improved bone stock assessment, while porous metal augments and custom implants show encouraging results for complex defects, though long-term data and cost-effectiveness remain uncertain. Reduced osteolysis prevalence may ease acetabular reconstruction, but increasing re-revision volumes present ongoing challenges for bone defect management.
89. Thota PK, Cohen J, Selemon NA, et al. Referral Patterns and Clinical Outcomes in Revision Total Hip Arthroplasty: A Single-Surgeon Tertiary Care Center Series. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.10.010
A retrospective review of 242 consecutive revision total hip arthroplasties performed by a single surgeon categorized patients by referral status (internal to surgeon, internal to hospital, or external) and compared demographics, indications, HOOS scores, and re-revision rates. Externally referred patients had substantially higher prior revision rates (41.8% vs 4.2%), though final HOOS scores were similar across groups. The findings suggest tertiary centers should expect greater revision complexity in external referrals, but outcomes can be comparable, informing referral triage and counseling.
90. D’Apollonio TM, Oteman BP, Hopman ML, et al. Porous Tantalum Acetabular Components in Complex Revision Total Hip Arthroplasty: The Influence of Defect Severity and Intraoperative Fixation. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.10.013
This study analyzed 345 revision hip arthroplasties with porous tantalum acetabular components over two decades, using cumulative incidence and subdistribution hazard analyses stratified by Paprosky defect type, pelvic discontinuity, and fixation method. Re-revision for aseptic loosening was low (0.87%, 1.84%, and 2.72% at two, five, and 10 years). The results support porous tantalum constructs as durable even in severe acetabular bone loss, with defect severity and fixation details guiding risk stratification.
91. Kayani B, Drummond I, Merchant A, et al. Custom Triflange Acetabular Components in Revision Total Hip Arthroplasty: Survivorship, Clinical Outcomes and Risk Factors for Failure. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.10.009
Fifty-six patients with advanced acetabular bone defects underwent revision THA with custom triflange acetabular components and were followed for a mean of 44.8 months for survivorship, functional scores, osseointegration, and complications. Implant survivorship was 94.3% for aseptic loosening, with five revisions (three aseptic loosening, two infection), and functional scores improved substantially. Custom triflange components appear reliable for major acetabular defects, with infection and loosening as key failure modes to monitor.
Hip Fracture Care (11)¶
39. Bhattacharyya T. Delay Is Associated with Death. Journal of Bone and Joint Surgery 2026. doi:10.2106/jbjs.26.01058
This commentary discusses King et al.'s matched-cohort study of 2,358 UK hip fracture patients, which isolates the effect of capacity-related surgical delay on mortality. The study provides near-definitive evidence that delays attributable to operating room availability, not just patient condition, increase 30-day mortality. This strengthens the surgeon's argument for prioritizing urgent hip fracture fixation and has implications for hospital resource allocation and after-hours staffing.
43. Miyamoto S, Yoshii Y, Ishii T. Comorbidity burden and fracture pattern as predictors of early postoperative medical complications following bipolar hemiarthroplasty for displaced femoral neck fractures: a retrospective cohort study. Archives of Orthopaedic and Trauma Surgery 2026. doi:10.1007/s00402-026-06526-7
In 297 patients (310 hips) undergoing bipolar hemiarthroplasty for displaced femoral neck fractures, this retrospective cohort used multivariable logistic regression to identify predictors of medical complications within 30 days, evaluating Charlson and Elixhauser comorbidity indices, comorbidity-polypharmacy score, and fracture pattern. Comorbidity burden and fracture pattern emerged as independent predictors of early postoperative medical complications, with implications for 1-year survival. Preoperative assessment of comorbidity burden and fracture morphology can guide risk stratification and postoperative surveillance in these frail patients.
45. Närhi SCF, Rasmussen LE, Rogmark C, et al. Dislocations after hip hemiarthroplasty for acute femoral neck fractures: a scoping review. Injury 2026. doi:10.1016/j.injury.2026.113637
This scoping review mapped the literature on dislocation after hip hemiarthroplasty for acute femoral neck fracture, summarizing reported incidence, risk factors, and preventive strategies. Dislocation remains a clinically important complication of hemiarthroplasty in the fracture population. The review highlights gaps in the evidence base and can inform surgical decision-making (e.g., approach selection) and patient counseling regarding dislocation risk.
49. Rashidian L, Ali A, Senthinathan A, et al. Risk factors and hospital harm: A study of hip fracture patients in the community using population-based data. Injury 2026. doi:10.1016/j.injury.2026.113510
Using linked administrative data on 124,570 community-dwelling Ontarians aged 50+ hospitalized with hip fracture (2008-2022), the authors used multivariable logistic regression, stratified by length of stay, to identify individual, neighborhood, and organizational risk factors for preventable hospital harm. The study quantifies how patient and system-level characteristics contribute to in-hospital harm in this population. Findings can inform targeted interventions and resource allocation to reduce preventable complications in hip fracture care.

Finite element analysis compared five fixation constructs for posterior acetabular column fractures, single and double both-column screws (BCS), single and double plates, and a combined BCS+plate construct, under level walking, stair ascent, and descent loading. The single-plate model showed the highest deformation and fracture gap values across all loading conditions, while BCS-based constructs performed favourably. These results support the biomechanical viability of BCS-based fixation and can guide construct selection in acetabular fracture surgery.

This review proposes a pragmatic multidisciplinary framework, grounded in Level 1 Trauma Centre practice and international guidelines (NICE, AAOS, anaesthetic and regional anaesthesia societies), for perioperative management of anticoagulated hip fracture patients. It prioritizes surgery within 24 hours (no later than 48 hours), guided by active haemostatic assessment with drug-specific assays, and integrates reversal strategies, regional anaesthesia safety, and Patient Blood Management. The framework aims to minimise surgical delays and improve survival and functional recovery.

Finite element models of unstable AO/OTA 31A2.2 intertrochanteric fractures, with and without a gap, were implanted with intramedullary nails of 170-280 mm and subjected to simulated stair climbing to assess interfragmentary motion and implant stress. Interfragmentary motion decreased with increasing nail length, plateauing at 260 mm or greater, while implant stress was not significantly related to nail length. The findings suggest that longer nails (≥260 mm) provide optimal mechanical stability in this fracture pattern.

A two-round modified-Delphi study involving 67 and 55 panellists from 17 countries (anaesthetists, orthopaedic/trauma surgeons, and geriatricians) developed consensus statements on operative and non-operative hip fracture management. Fourteen of 15 statements (93%) achieved high consensus (≥70% agreement), while only 24% of panellists' facilities had protocols for non-operative care. The statements support shared decision-making and more consistent, standardised non-operative hip fracture management internationally.

An ethnographic field study at a Danish orthopaedic ward used 22 observation sessions, 230 pages of field notes, and 23 stakeholder interviews to characterize actual clinical practice around mobilization, basic mobility, physical activity, and exercise after hip fracture surgery. The study confirmed substantial physical inactivity during acute admission, indicating poor implementation of guideline recommendations. Clinically, it points to the need for standardised, structured mobilization protocols and system-level changes to bridge the evidence-practice gap.

This retrospective two-center cohort study compared cannulated screws, dynamic hip screws, and the Femoral Neck System (FNS) in 207 adults with transcervical femoral neck fractures treated between 2019 and 2024, with minimum 12-month follow-up. The authors hypothesized the FNS would yield lower reoperation rates than the traditional implants, though baseline differences in age and Garden classification existed between groups. The study addresses a key evidence gap on implant choice for these high-failure fractures, informing fixation selection in clinical practice.

This study examined the association between anaesthesia type (general versus regional) and postoperative outcomes in frail patients undergoing hip fracture fixation. General anaesthesia was associated with increased postoperative morbidity and mortality in this frail population. The findings support careful anaesthetic selection, favouring regional techniques where feasible, in frail hip fracture patients.

Five surgeons who transitioned from posterior or anterolateral to the direct anterior approach for total hip arthroplasty had their early direct anterior cases compared 1:1 with their prior-approach cases (618 patients total), with radiographic parameters analyzed for precision. The direct anterior approach demonstrated greater precision in implant placement even during the early learning curve compared with the surgeons' previous approaches. These findings suggest concerns about reduced accuracy during the learning curve for the direct anterior approach may be unfounded.
19. Jiang L, Hao M, Wang M, et al. Computer‐Assisted Hip Arthroscopy for Portal Establishment and Suture Anchor Placement. Arthroscopy Techniques 2026. doi:10.1002/atn2.70317
A surgical technique article describes computer-assisted navigation for hip arthroscopy, using preoperative CT-based 3D modeling and 2D-3D image registration to plan and execute portal establishment and suture anchor placement for labral repair. The navigation system allows precise, individualized targeting of the anterolateral portal and anchor sites. This approach may shorten the steep learning curve and reduce iatrogenic cartilage and labral injury during hip arthroscopy.

This is a correction notice for a cadaver-based study of robotic-arm assistance in revision total hip arthroplasty. The only change was to the Figure 1 caption, where the phrase 'accepted manuscript' was erroneously inserted and has been removed. No scientific content or conclusions of the original study were altered.

Using a national administrative database, this study compared robotic-assisted and computer-navigated THA versus manual THA in patients with osteonecrosis of the femoral head, with 1:4 matching on demographics and comorbidities. Neither robotic nor navigated techniques reduced 90-day medical adverse events or 5-year implant-related complications compared with manual THA. These findings suggest no clear technology-based advantage for this higher-risk indication, implying that technology use should not be prioritized on the basis of osteonecrosis diagnosis alone.

This systematic review of 13 comparative studies (2015-2025) synthesized evidence on robot-assisted versus conventional total hip arthroplasty regarding implant positioning, biomechanical restoration, function, and complications. Robot-assisted THA consistently improved acetabular component placement accuracy and limb length restoration, but functional outcomes were inconsistent across studies with no clear clinical benefit demonstrated. The improved radiographic precision of robotic assistance does not yet translate into proven superior clinical outcomes, tempering the rationale for its added cost.

In a biomechanical cadaveric study of 20 femora, investigators compared cumulative, mean, and maximum forces and number of strikes during femoral broaching for THA using straight versus offset broach handles, with subgroup analysis by Dorr canal morphology. The offset handle required significantly more strikes to seat the planned broach size, though other force measures did not differ significantly. These findings suggest offset broach holders may increase intraoperative femoral stress and potentially perioperative fracture risk, favoring straight handles when feasible.

A retrospective single-surgeon analysis of 640 consecutive anterolateral supine total hip arthroplasties used CUSUM analysis of operative time and blood loss plus change-point analysis of complications to define the learning curve. CUSUM curves peaked around cases 411-437, indicating a prolonged learning phase for this approach. Surgeons adopting the anterolateral supine technique should anticipate an extended learning curve before performance plateaus, relevant to training and case-volume planning.

Using a national database, this propensity score-matched cohort study analyzed 7,174 primary cemented femoral fixation total hip arthroplasties to compare five-year outcomes between low-volume (<60 stems) and higher-volume (≥60 stems) cemented surgeons. Patients of low-volume surgeons had higher rates of all-cause revision, periprosthetic fracture, mechanical loosening, infection, and dislocation, with significantly higher odds of revision at two years. The results suggest surgeon cemented volume is an important determinant of implant survivorship, with implications for surgeon training and adoption of cemented fixation as its U.S. usage evolves.

This retrospective cohort study compared outcomes of 227 cemented (using the line-to-line 'French Paradox' technique) versus 302 uncemented wedge-taper femoral stems in hip arthroplasty at a single academic center from 2013 to 2020. Cemented and uncemented stems showed similar 90-day readmission rates, with comparable subsidence and low complication rates. The findings support the French Paradox cementing technique as a safe and viable fixation method with outcomes comparable to uncemented fixation.

This prospective study of 49 patients (51 hip resurfacing arthroplasties) used pre- and postoperative CT scans to assess the accuracy of patient-specific instrumentation (PSI) for femoral component placement. PSI achieved femoral component alignment within 5 degrees of the planned axis in axial and coronal planes, and 3D planning reproduced native head diameter within one implant size (2 mm). PSI may shorten the learning curve for hip resurfacing by improving implantation accuracy, particularly valuable in this technically demanding procedure for young patients.

This Danish multicenter cohort study of 6718 hip and knee arthroplasty procedures examined how different arthroplasty center setups influenced implementation of a standardised day-case setup and day-of-surgery discharge rates. Arthroplasty centers that were logistically separated from general orthopaedic departments achieved more successful implementation of the standardised day-case pathway. Organizational separation may be a key consideration when establishing day-case arthroplasty programs to reduce bed occupancy and improve cost-effectiveness.

Archives of Orthopaedic and Trauma Surgery 2026. doi:10.1007/s00402-026-06516-9
This prospective cohort of 85 patients (53 with 12-month follow-up) examined which preoperative variables predicted achieving the minimal clinically important difference on the WOMAC-function subscale one year after total hip arthroplasty. Preoperative pain intensity was independently associated with clinically meaningful functional improvement, with an exploratory NRS pain threshold of 6.5 showing moderate discriminative capacity (AUC 0.740). Preoperative pain may serve as a simple benchmark for risk stratification and expectation setting before THA.

Supervised machine learning with SHAP interpretation was applied to 3,025 consecutive patients undergoing primary hip and knee arthroplasty within a universal, non-selective ERAS pathway to identify perioperative factors associated with failure of Day 0/Day 1 and same-day discharge. The models showed good discriminative performance, with pathway-related perioperative variables (beyond patient characteristics) among the key predictors. These findings support using ML-informed, modifiable pathway factors to optimise discharge planning even in unselected arthroplasty populations.

This longitudinal registry study used group-based trajectory modelling in 15,197 individuals with knee or hip osteoarthritis participating in a digital education and exercise therapy program to identify physical activity trajectories over one year and associated factors. Distinct PA trajectories were identified, with the proportion meeting recommended activity levels varying by trajectory, and patient-reported outcomes differed across trajectories. Identifying patients on less favourable trajectories early could allow targeted support within digital OA management programs.

This systematic review synthesized evidence on fear-related psychological constructs and recovery after total hip and knee arthroplasty, organizing them into the FEAR Framework (Fall Confidence, Exposure Avoidance, Anticipatory Anxiety, Reinjury Fear) and cataloging validated patient-reported outcome measures. Fear-related factors, especially kinesiophobia and pain catastrophizing, were consistently associated with worse postoperative outcomes. Clinically, the framework offers a structured way to identify modifiable psychological barriers and to recognize non-mechanical contributors to discordant or unsatisfactory recovery.

The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.09.040
This retrospective single-surgeon study compared 63 patients aged 70 and older undergoing single-stage bilateral total hip arthroplasty with 271 similar-aged unilateral THA patients, assessing 90-day complications and patient-reported outcomes to one year. No differences were found in early complications or one-year PROs between the groups, though the bilateral cohort had longer length of stay, lower rates of direct home discharge, and higher transfusion rates. These findings suggest single-stage bilateral THA can be considered in selected patients 70 and older, provided the increased perioperative resource needs are anticipated.

This umbrella review of 25 systematic reviews encompassing over 40,000 patients examined psychological factors associated with function and health-related quality of life after total hip or knee arthroplasty. Depression and anxiety were consistently identified as vulnerability factors negatively affecting postoperative outcomes, with distress, kinesiophobia, pain catastrophizing, and pessimism also showing negative impacts. Clinicians should screen for these psychological factors preoperatively, as they may identify patients at risk for poorer functional and quality-of-life outcomes.

This dose-response analysis of a claims database matched 77,958 primary THA patients with preoperative SSRI prescriptions to 233,277 SSRI-naive controls, stratifying SSRI exposure into low, medium, and high daily doses. Preoperative SSRI use was associated with increased 2-year complication rates (5.2% vs 3.2%), with risk varying by dose. Surgeons should recognize preoperative SSRI use as a potential risk factor for postoperative complications after THA, though the underlying indication (depression/anxiety) was controlled for in matching.

A web-based national survey of Brazilian Hip Society members assessed recommendations for 40 physical activities across three postoperative periods after THA, analyzed with binomial testing to classify activities as recommended, recommended with caution, not recommended, or inconclusive. The survey generated consensus-based, Brazil-specific guidance on sport permission and resumption timelines. These results address the lack of standardised national guidelines and may inform counseling of active Brazilian THA patients.

Using Danish national register data, 5,187 dual-mobility cups were compared with 35,162 standard 36 mm-head and 15,702 standard 32 mm-head cups in primary THA for osteoarthritis, with 10-year all-cause and cause-specific revision risks standardised to the combined population. The study quantifies long-term revision risk differences between cup types in a nationwide cohort. These findings inform implant selection where dislocation risk reduction must be weighed against long-term revision outcomes.

This registry-based study of 300 hip arthroscopy patients for femoroacetabular impingement syndrome used multivariable regression to assess whether baseline resilience correlates with baseline pain, function, and mental health. Baseline resilience was associated with baseline mental health but not with baseline pain or functional status. Resilience screening alone may not predict preoperative pain or function, and other factors should be considered when evaluating patients before hip arthroscopy.

This retrospective cohort of 2,522 patients treated with arthroplasty for femoral neck fracture (885 THA, 1,637 hemiarthroplasty) identified demographic, clinical, and laboratory predictors of revision. Revision rates were substantially higher after THA (10.5%) than hemiarthroplasty (2.6%), with THA revisions associated with younger age, shorter hospital stays, and higher postoperative hemoglobin among other factors. These risk factors and ROC-derived cutoffs can aid preoperative risk stratification and postoperative surveillance in fracture arthroplasty patients.

This technical note introduces a supine modification of the Ober's test for external snapping hip, performed with the patient supine through combined internal rotation/adduction and passive hip flexion-extension to elicit palpable or visible snapping at the greater trochanter. Compared with the lateral decubitus version, the supine test allows simultaneous bilateral, dynamic assessment without repositioning, shortens examination time, and is particularly useful intraoperatively to confirm adequacy of soft tissue release. It offers a convenient adjunct for diagnosing and surgically managing external snapping hip in the supine position.

This systematic review of 14 observational studies evaluated whether systemic antifibrotic agents (statins, ARBs, ACEIs) prevent postoperative arthrofibrosis after shoulder, knee, and hip surgery. Evidence was mixed: some TKA studies linked ARB use to reduced manipulation under anaesthesia or adhesion lysis, while others found no effect on MUA, range of motion, or arthrofibrosis, and ACEI and statin results were inconsistent; most studies had serious risk of bias. Current evidence does not support routine use of these agents for arthrofibrosis prevention, and higher-quality prospective studies are needed.

In 54 hips from 45 female patients undergoing joint-preserving surgery for developmental dysplasia of the hip, labral injuries on radial MRI were classified as simple or complicated and correlated with subchondral bone density (CT-OAM) and finite element analysis of contact stress. Complicated labral injuries were associated with localized stress concentration in the superior acetabulum, reflected by an increased high-density area on CT-OAM. This suggests that severe labral pathology in dysplastic hips both reflects and may perpetuate abnormal superior acetabular loading, supporting early recognition and correction of dysplastic mechanics to protect cartilage.

A cost-effectiveness analysis compared silk dressings with 2-octyl cyanoacrylate mesh dressings after total hip and knee arthroplasty, incorporating material costs, application time, and complication-related expenses (hypersensitivity, wound healing, periprosthetic joint infection). Silk dressings were substantially less costly, saving roughly $690-$939 per patient depending on pricing. The results favour silk dressings as the more economical wound-closure choice in routine arthroplasty practice.

A retrospective comparative study of 494 patients evaluated biomechanical restoration (offsets, leg length, abductor lever arm) and clinical outcomes after direct anterior approach total hip arthroplasty in obese versus non-obese patients. Restoration and precision within target zones were comparable between groups and independent of BMI, with abductor lever arm alignment influencing outcomes. Obesity should not be considered a barrier to achieving accurate alignment with the direct anterior approach.

In this retrospective study of 438 cam-positive hips (126 with end-stage primary osteoarthritis, 312 non-arthritic fracture hips), radial CT-based alpha angle, three-dimensional cam volume, cam/head volume ratio, and lesion location were compared between groups. Hips with end-stage osteoarthritis showed greater three-dimensional cam burden and a more superolateral lesion location. These findings suggest that cam size and location may identify which cam-positive hips are at risk of progressing to joint failure, informing patient selection for hip-preserving surgery.

Using prospectively collected data from 94 revision hip arthroscopies with minimum 5-year follow-up, PASS thresholds were derived via ROC analysis for mHHS, NAHS, VAS, and iHOT-12, and agreement with patient-reported satisfaction was assessed. The PASS thresholds showed imperfect agreement with satisfaction, indicating that scoring above a threshold does not guarantee patients consider themselves satisfied. Clinicians should interpret PASS classifications alongside direct satisfaction anchors when counseling revision hip arthroscopy patients.

A multimodal deep learning model was developed using biparametric MRI (STIR and T1-FSE sequences) plus clinical parameters in 530 patients (851 hips) to differentiate early- from late-stage osteonecrosis of the femoral head. The integrated bpMRI-clinical model outperformed single-sequence and clinical-only models for stage stratification. The model could provide objective, reproducible imaging-based staging to guide selection of hip-preserving treatments.

The authors describe a technical note for anchor-free capsular augmentation in hip arthroscopy using the reflected head of the rectus femoris, employing a capsule-tendon-capsule suture construct rather than suture anchors. This approach simultaneously closes and reinforces the capsule without additional implants while preserving the tendon's dynamic stabilizing function. It offers a simple, reproducible, and cost-effective option for patients at risk of postoperative microinstability after extensive capsulotomy.

This retrospective study of 86 hips evaluated whether the traditional 8-mm anterior acetabular overhang threshold should guide treatment of iliopsoas impingement after THA, comparing outcomes of arthroscopic iliopsoas fractional lengthening in patients with <8 mm versus ≥8 mm overhang. The findings challenge the established cutoff, suggesting that arthroscopic lengthening can succeed even with greater overhang. Clinically, this may reduce the number of patients routed to acetabular revision for iliopsoas impingement.

This commentary discusses the large Swiss registry study by Bouché et al. examining the impact of femoral stem design on periprosthetic femoral fracture risk across 182,118 primary THAs. It highlights that beyond fixation method and patient factors, stem design, particularly the difference between taper-slip and composite-beam designs, substantially influences fracture risk. The commentary underscores that stem design choice should be a deliberate consideration, especially given rising periprosthetic fracture rates in an aging prosthetic population.

This commentary reviews Adolf et al.'s 17-country analysis projecting revision hip and knee arthroplasty volumes through 2060 using a consistent methodology applied to worldwide registry data. By applying age-stratified revision rates to UN population estimates rather than extrapolating raw procedure counts, the study offers a more conservative and methodologically sound projection than prior country-specific studies. The commentary emphasizes the importance of standardized methodology when projections inform resource allocation decisions.

Using the National Inpatient Sample (2016-2021), this retrospective cohort study applied inverse probability of treatment weighting and doubly adjusted regression to compare in-hospital outcomes of elective primary total hip arthroplasty between patients with coded rheumatoid arthritis and those with primary hip osteoarthritis. The findings indicate whether RA confers excess short-term perioperative morbidity in contemporary U.S. practice. Results inform preoperative risk counseling and resource allocation for RA patients undergoing THA.

This retrospective cohort study compared 95 obese with 438 non-obese patients undergoing proximal femoral nailing of intertrochanteric femoral fractures in the lateral decubitus position, assessing reduction quality and clinical/radiological outcomes. Obesity was associated with longer operative time and higher ICU admission rates, while hospital stay and Harris Hip Scores were comparable between groups. Surgeons can expect acceptable functional outcomes in obese patients but should anticipate longer procedures and greater perioperative resource use.
47. Scuderi GR, Henry JP, Mont MA. Meeting Patient Expectations for Return to Recreational Activities. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.08.023
This narrative review discusses evolving patient expectations for return to recreational activities after total hip and knee arthroplasty and how preoperative expectations relate to postoperative satisfaction and patient-reported outcomes. It emphasizes that satisfaction depends on aligning patient goals with realistic activity outcomes rather than pain relief alone. Surgeons should proactively counsel patients on which recreational activities are reasonable and safe after joint replacement to meet expectations.

This letter to the editor critiques a nationwide claims-based analysis linking metabolic syndrome to higher rates of surgical site and periprosthetic joint infection after elective total hip arthroplasty, which identified abdominal obesity as the dominant correlate. The authors raise methodological and clinical concerns about the operational MetS definition and analytic approach. The exchange underscores caution when using coded cardiometabolic clustering to guide preoperative optimization decisions in arthroplasty candidates.

A single-centre cohort of 52 hips in 51 geriatric patients (median age 85) with non-reconstructable native or periprosthetic acetabular fractures was treated with single-stage navigated percutaneous anterior and posterior column screw fixation combined with total hip arthroplasty. Clinical and radiological outcomes, including walking ability, living independence, EQ-5D-5L, and Forgotten Joint Score, were retrospectively evaluated. The technique appears to permit immediate mobilization with minimal operative burden, offering a viable option for frail elderly patients.
52. Ecker N, Simon M, Lisitano L, et al. Subtrochanteric varisation explains age-related changes in proximal femoral morphology and has implications for hip arthroplasty and trauma surgery. Injury 2026. doi:10.1016/j.injury.2026.113524
Analysis of 100 pelvic-leg CT angiographies examined correlations between the caput-collum-diaphyseal angle (CCD) and trochanteric rotation/offset parameters to localize the anatomical origin of age-related femoral varus remodeling. The modified CCD correlated negatively with age, and the critical trochanter angle correlated significantly with CCD, indicating that varisation originates subtrochanterically rather than at the hip joint. This has implications for implant positioning and surgical planning in hip arthroplasty and geriatric fracture care.
55. Pass B, Boerner A, Bousch J, et al. Cytokine release after geriatric coxal monotrauma. Injury 2026. doi:10.1016/j.injury.2026.113619
Cytokine profiles (IL-6, IL-10, MCP-1/CCL2) were measured preoperatively and over the first postoperative week in geriatric patients with proximal femur fractures, compared with geriatric elective hip arthroplasty patients and young healthy controls. Preoperative IL-6 and IL-6/IL-10 ratios were significantly elevated in trauma patients, indicating a distinct inflammatory response to geriatric hip monotrauma. These findings may help identify patients at risk of adverse postoperative outcomes and guide immune-modulating strategies.

The authors present four illustrative case scenarios applying the new Association Research Circulation Osseous (ARCO) clinical practice guideline for nontraumatic osteonecrosis of the femoral head, the first international evidence-based guideline for this condition. The cases walk through imaging selection, symptom evaluation, collapse-risk estimation, observation, joint-preserving surgery, and total hip arthroplasty decision-making across a range of disease presentations. The paper serves as a practical implementation guide, helping clinicians translate the ARCO recommendations into everyday diagnostic and treatment decisions.

This descriptive laboratory study compared extracellular matrix density, vascularity, and progenitor cell (CD90/CD105) density across glenoid and acetabular labrum regions from 16 human donors aged 59 to 96. The vascular region of each labrum showed higher interfibrillar area and vessel density than the avascular region, with regional differences in histological features relevant to healing potential. These findings provide a histological basis for the location-dependent healing prognosis of labral tears in the shoulder and hip, informing decisions about repair versus reconstruction.

This narrative review synthesised evidence on metal hypersensitivity in total joint arthroplasty, covering immune mechanisms, clinical presentations, and diagnostic strategies including patch testing, lymphocyte transformation testing, and histopathology. Metal hypersensitivity was associated with a subset of implant failures manifesting as persistent pain, chronic inflammation, and aseptic loosening, but no gold-standard diagnostic method exists and the evidence base remains limited. Clinicians should consider hypersensitivity in unexplained implant-related symptoms, though diagnostic uncertainty currently precludes firm consensus-based recommendations.

This review summarizes the evaluation and management of symptomatic Charcot arthropathy of the hip and knee, covering nonoperative measures and outcomes of total joint arthroplasty. Although arthroplasty can improve pain and function, complication rates are high (approximately 20-30% for TKA and 45-58% for THA), with instability, infection, and mechanical failure most common. Success hinges on careful patient selection, optimization of modifiable risk factors such as glycemic control, and use of constrained or dual mobility constructs.
