Highlights¶
TKA Alignment, Robotics, and Implants¶
Recent literature highlights advancements in total knee arthroplasty (TKA) precision and implant longevity. Robotic platforms, including image-based and imageless systems, demonstrate equivalent accuracy in achieving planned femoral rotation [1], while intraoperative 3D scanning offers real-time alignment assessment [16]. The role of large language models in answering TKA clinical questions is comparable across major platforms [17], and bibliometric analyses reveal a paradigm shift toward personalized alignment strategies [88]. Regarding implants, condylar-constrained prostheses show favorable survival in aseptic revisions [13], and femoro-tibial size mismatch does not increase polyethylene wear in fixed-bearing designs [109]. Additionally, posterior condylar offset and joint-line restoration are linked to improved patient-reported outcomes in robotic-assisted TKA [92].
ACL Reconstruction and Ligament Injuries¶
Studies on anterior cruciate ligament (ACL) reconstruction focus on surgical techniques, risk factors, and outcomes. Increased posterior tibial slope is associated with primary repair failure [10], while lateral extra-articular procedures reduce graft failure rates [24] and adding lateral tenodesis to quadriceps autografts further lowers failure risk [66]. Anatomical factors like the lateral femoral condyle angle predict primary and rerupture injuries [51]. Postoperative recovery is influenced by early extension deficits affecting cartilage degeneration [40] and persistent muscle inhibition [46]. Furthermore, concomitant meniscal repair preserves outcomes without increasing reoperation rates [44], and posterior medial meniscus root repair during ACL reconstruction yields favorable results in nondegenerative cohorts [110].
Patellofemoral Instability and Alignment¶
Research on patellofemoral instability addresses diagnostic thresholds, surgical outcomes, and anatomical considerations. Patellar height measures are affected by trochlear dysplasia and imaging techniques [8], while sex and height impact tibial tuberosity-trochlear groove distance thresholds [14]. Isolated medial patellofemoral ligament reconstruction (MPFLR) provides similar outcomes in patients with increased TT-TG distances [19] but may reduce patellar height and cause quadriceps dysfunction [18]. Concomitant cartilage restoration does not consistently improve MPFLR outcomes [49]. Biomechanical studies indicate that anteromedializing tibial tubercle osteotomy does not fully restore native pressures in high anteversion models [34], and MRI enables precise quantification of patellar engagement after distalization osteotomies [86].
Osteotomy, Meniscus, and Cartilage Restoration¶
This theme covers osteotomies, meniscal surgery, and cartilage restoration. High tibial osteotomies are used to correct posterior tibial slope in PCL insufficiency [20], [48], with anterior cortical defects showing consistent remodeling [31]. Meniscal slope and tibial slope are risk factors for meniscal tears [12], and lateral extra-articular procedures may affect meniscal root tension [33]. Meniscal allograft transplantation using bone-bridge techniques improves outcomes [80], while suture-only fixation increases reoperation rates compared to bone plug methods [22]. Saucerization of discoid menisci requires careful residual width management to prevent complications [63], and concomitant alignment or meniscal surgery improves cartilage restoration outcomes [26].
TKA Outcomes, Complications, and Patient Factors¶
Patient-reported outcomes and complications in TKA are heavily influenced by preoperative factors and surgical details. 'Overall pain' is the strongest predictor of satisfaction [21], while depression predicts worse postoperative function [94]. Obesity and prior bariatric surgery do not necessarily increase reintervention risks [37], [59]. Perioperative management includes dexamethasone reducing VTE risk [104] and periarticular injections providing comparable early recovery to nerve blocks [105]. Tourniquet strategies impact blood loss [98], and cement viscosity influences long-term loosening risks [95]. Revision TKA for aseptic loosening is projected to increase in volume and cost [100], and conversion from patellofemoral arthroplasty has specific survivorship patterns [112].

This study compared the rotational accuracy of image-based and imageless robotic platforms in primary total knee arthroplasty using pre- and postoperative CT scans. The findings demonstrated that both platforms achieved equivalent accuracy in achieving planned femoral rotation within a ±1° margin. Clinically, this suggests that surgeons can choose either robotic platform without compromising rotational precision in TKA.
13. Tyas B, Hewitt C, Deehan D, et al. Condylar‐constrained prostheses are associated with favourable implant survival following first‐time aseptic revision knee arthroplasty: An analysis from the National Joint Registry. Knee Surgery, Sports Traumatology, Arthroscopy 2026. doi:10.1002/ksa.70548
This study assessed MRI-based thresholds for tibial tuberosity to trochlear groove distance in identifying patellar instability, accounting for patient sex and height. The diagnostic threshold for malalignment varied significantly based on whether patients were female or male and their height. These sex- and height-specific thresholds improve the accuracy of MRI-based diagnosis for patellar instability.
16. Rath B, Huber T, Kamper M, et al. Feasibility and accuracy of intraoperative 3D surface scanning to assess femoral component alignment relative to the native distal femoral articular surface in total knee arthroplasty. Knee Surgery, Sports Traumatology, Arthroscopy 2026. doi:10.1002/ksa.70542
This experimental study evaluated the feasibility and accuracy of intraoperative 3D surface scanning to assess femoral component alignment in total knee arthroplasty. The scanning method provided high-resolution anatomical data with approximately 0.2 mm accuracy, with landmark-based registration proving more precise than marker-based methods. Intraoperative 3D scanning offers a viable tool for real-time alignment verification during surgery.
17. Pujol O, Ferrer R, Coelho A, et al. Four general‐purpose large language models (ChatGPT‐5, Claude 4, Grok 4 and Gemini 2.5) show comparable performance in specialised total knee arthroplasty clinical questions. Knee Surgery, Sports Traumatology, Arthroscopy 2026. doi:10.1002/ksa.70544
This cross-sectional study compared the performance of four large language models in answering specialized total knee arthroplasty questions using a blinded human assessment framework. Gemini 2.5 achieved the highest overall scores, though all four models demonstrated comparable, high-level performance in accuracy and comprehensiveness. These findings suggest that general-purpose LLMs are viable tools for providing reliable, evidence-based information in orthopedic clinical contexts.
88. Micicoi G, Sculco PK, Parker DA, et al. The 100 Most Cited Publications on Alignment in Total Knee Arthroplasty: A Bibliometric Analysis Revealing a Paradigm Shift Toward Personalized Alignment Strategies. Journal of ISAKOS 2026. doi:10.1016/j.jisako.2026.101180
A bibliometric analysis of the 100 most cited publications on alignment in total knee arthroplasty revealed a paradigm shift toward personalized alignment strategies. The review identified evolving trends in the literature that prioritize individualized surgical approaches over traditional mechanical alignment. This insight informs current surgical practices and future research directions in knee arthroplasty alignment.
92. Suhardi VJ, McCormick K, Hepinstall M, et al. Posterior Condylar Offset and Joint-Line Restoration Are Associated with Improved Patient-Reported Outcomes After Robotic-Arm-Assisted Total Knee Arthroplasty. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.06.080
This retrospective analysis of robotic-arm-assisted total knee arthroplasty identified that preserving posterior condylar offset and restoring the joint line are significantly associated with improved patient-reported outcomes. These findings imply that surgeons should prioritize these specific sagittal alignment parameters during robotic TKA to optimize functional recovery and patient satisfaction.
109. Mancino F, Sabharwal N, Greenaway M, et al. Femoro-Tibial Size Mismatch Does Not Increase Polyethylene Wear in Fixed-Bearing Total Knee Arthroplasty: A Retrieval Analysis. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.07.053
This retrieval analysis investigated whether femoro-tibial size mismatch increases polyethylene wear in fixed-bearing total knee arthroplasty implants. The study found no significant difference in total polyethylene wear between matched and mismatched components, contradicting the hypothesis that mismatch accelerates wear. This suggests that minor size mismatches do not necessarily compromise implant longevity, potentially allowing for greater intraoperative flexibility in component selection.
ACL Reconstruction and Ligament Injuries (8)¶
10. Arras C, Mueller MM, Conner‐Rilk S, et al. Increased posterior tibial slope is associated with failure after anterior cruciate ligament primary repair. Knee Surgery, Sports Traumatology, Arthroscopy 2026. doi:10.1002/ksa.70543
This retrospective study analyzed whether preoperative posterior tibial slope and notch morphology predict failure after anterior cruciate ligament primary repair. Increased posterior tibial slope was identified as a significant risk factor for graft failure within two to five years post-surgery. Clinicians should consider these anatomical factors when selecting patients for primary repair versus reconstruction.
24. Macciacchera M, Nucci N, Hayes E, et al. Lateral Extra‐articular Procedures Decrease Rates of Graft Failure and Positive Pivot Shift in Primary Anterior Cruciate Ligament Reconstruction: A Systematic Review and Meta‐analysis. Arthroscopy 2026. doi:10.1002/arj.70413
This systematic review and meta-analysis evaluated the impact of lateral extra-articular procedures on outcomes following primary anterior cruciate ligament reconstruction. The addition of lateral extra-articular procedures significantly reduced graft failure rates and positive pivot shift findings compared to reconstruction alone. These findings support the routine consideration of lateral extra-articular augmentation to enhance stability and reduce failure risks in primary ACL reconstruction.
40. Allison A, Harrington J, Weaver B, et al. Association of Early Knee Extension Range of Motion Deficits With Cartilage T2 Relaxation Following Anterior Cruciate Ligament Reconstruction. The American Journal of Sports Medicine 2026. doi:10.1177/03635465261462587
This cohort study investigated the association between early knee extension range of motion deficits and cartilage T2 relaxation times following anterior cruciate ligament reconstruction. It found that extension deficits at two months post-surgery were associated with worsening cartilage T2 relaxation times at six months. This suggests that early restoration of full extension is crucial for preserving cartilage health and potentially preventing osteoarthritis.
44. Kekki C, Cristiani R, Stålman A, et al. Concomitant meniscal repair and resection are not associated with ACL reoperation, and successful meniscal repair preserves patient‐reported outcomes: A 2‐year retrospective cohort study. Knee Surgery, Sports Traumatology, Arthroscopy 2026. doi:10.1002/ksa.70516
This retrospective cohort study compared 2-year reoperation rates and patient-reported outcomes between isolated ACL reconstruction and cases with concomitant meniscal repair or resection. The results indicated that concomitant meniscal repair was not associated with increased ACL reoperation rates, and successful repairs preserved favorable patient-reported outcomes. Conversely, failed repairs were linked to inferior outcomes, suggesting that successful meniscal preservation is beneficial.
46. Barrera Uso M, Fayard J, Vieira TD, et al. Early arthrogenic muscle inhibition is the dominant predictor of persistent quadriceps inhibition after total knee arthroplasty. Knee Surgery, Sports Traumatology, Arthroscopy 2026. doi:10.1002/ksa.70518
This study assessed the prevalence and risk factors for arthrogenic muscle inhibition (AMI) in patients undergoing total knee arthroplasty. It identified pre-operative AMI as the dominant independent predictor of persistent quadriceps inhibition in the early post-operative period, alongside high BMI and long symptom duration. These findings suggest that pre-operative screening for AMI could help identify patients at risk for prolonged muscle dysfunction after surgery.
51. Wang D, Liu J, Du X, et al. Lateral Femoral Condyle Angle Is an Anatomic Risk Factor for Anterior Cruciate Ligament Primary Injury and Secondary Graft Rerupture. Arthroscopy 2026. doi:10.1002/arj.70322
This study assessed the lateral femoral condyle angle (LFCA) as a predictor for primary anterior cruciate ligament (ACL) injury and secondary graft rerupture. Results indicated that a larger LFCA is an independent anatomic risk factor for both primary ACL injuries and subsequent graft failures. Preoperative assessment of LFCA may help identify high-risk patients requiring tailored surgical or preventive strategies.
66. Renfree SP, Brinkman JC, Tummala SV, et al. Adding a Lateral Extra‐articular Tenodesis to Quadriceps Autograft Anterior Cruciate Ligament Reconstruction Reduces Risk of Graft Failure. Arthroscopy 2026. doi:10.1002/arj.70398
This study compared graft failure rates in primary ACL reconstruction using quadriceps tendon autograft with or without a lateral extra-articular tenodesis (LET). The addition of LET significantly reduced the graft failure rate from 29.6% to 14.8% and lowered the residual pivot shift rate. These findings suggest that adding LET improves graft survival and rotational stability in high-risk patients.
110. von Essen C, Sandon A, Barenius B, et al. Posterior Medial Meniscus Root Repair at the Time of Anterior Cruciate Ligament Reconstruction: Clinical Outcomes, Knee Stability, and Reoperations in a Nondegenerative Cohort. Journal of ISAKOS 2026. doi:10.1016/j.jisako.2026.101189
This retrospective cohort study assessed outcomes of posterior medial meniscus root repair performed concurrently with anterior cruciate ligament reconstruction in nondegenerative knees. Patients demonstrated favorable patient-reported outcomes and knee stability at two-year follow-up, with a low reoperation rate. These findings support the routine repair of posterior medial meniscus root tears during ACL reconstruction to preserve meniscal function and improve clinical results.
Patellofemoral Instability and Alignment (7)¶
8. Pace JL, James TE, Kamaci S, et al. Patellar Height Measures Are Affected by Patellar Position and Trochlear Dysplasia: Implications for Determining Patella Alta. Arthroscopy 2026. doi:10.1002/arj.70452
This study evaluated how patellar position and trochlear dysplasia influence patellar height measurements using MRI data from patients with and without patellar instability. The findings showed that patellar position significantly affects 1-image versus 2-image height measurements, and these measurements correlate with trochlear dysplasia indices. Clinically, this implies that patellar position must be considered when interpreting patellar height to accurately diagnose patella alta.
14. Nukala V, Sodhi A, Wadhavkar IT, et al. Sex and Height Impact Tibial Tuberosity to Trochlear Groove Distance Thresholds for Malalignment on Magnetic Resonance Imaging When Comparing Knees With Patellar Instability Versus Age‐ and Sex‐Matched Controls. Arthroscopy 2026. doi:10.1002/arj.70428
An analysis of the National Joint Registry compared implant survivorship and outcomes for different constraint levels in first-time aseptic revision knee arthroplasty. Condylar-constrained prostheses demonstrated favorable 10-year survival rates compared to other constraint levels. This supports the use of condylar-constrained implants for specific high-risk revision scenarios.
18. Sachdev D, Smelley C, Song C, et al. Isolated Medial Patellofemoral Ligament Reconstruction Reduces Patellar Height and Is Associated With Quadriceps Dysfunction. Arthroscopy 2026. doi:10.1002/arj.70422
This retrospective study evaluated the impact of isolated double-limbed medial patellofemoral ligament reconstruction on patellar height and quadriceps function in 81 patients. The findings indicate that the procedure significantly reduces patellar height and is associated with postoperative quadriceps dysfunction. These results suggest that surgeons should consider the potential for altered patellar mechanics and muscle weakness when planning isolated MPFL reconstruction.
19. Vincent JB, Erard J, Free M, et al. Isolated medial patellofemoral ligament reconstruction provides similar outcomes in patients with increased versus normal tibial tubercle–trochlear groove distance. Knee Surgery, Sports Traumatology, Arthroscopy 2026. doi:10.1002/ksa.70529
This prospective study compared clinical outcomes of isolated medial patellofemoral ligament reconstruction in patients with normal versus increased tibial tubercle–trochlear groove distances. Both groups showed comparable functional improvements and low recurrence rates, indicating that an increased TT-TG distance alone does not preclude successful outcomes with isolated MPFL reconstruction. Clinicians can consider isolated MPFL reconstruction for patients with increased TT-TG distances without necessarily requiring additional bony realignment procedures.
34. Morales‐Avalos R, Ceniceros‐Cantú C, Gutiérrez‐de la O J, et al. Anteromedializing tibial tubercle osteotomy does not restore femorotibial and patellofemoral pressures to native values in a human biomechanical model with increased femoral anteversion. Knee Surgery, Sports Traumatology, Arthroscopy 2026. doi:10.1002/ksa.70530
This cadaveric study evaluated the biomechanical effects of anteromedializing tibial tubercle osteotomy in knees with induced increased femoral anteversion. The procedure failed to restore patellofemoral and tibiofemoral pressures to native values, with internal femoral rotation significantly increasing lateral patellofemoral pressure. Clinically, this indicates that the osteotomy may not fully normalize joint mechanics in patients with significant femoral anteversion.
49. Duru DO, Wade D, Bouchard MD, et al. Concomitant cartilage restoration does not demonstrate consistent additional clinical benefit in medial patellofemoral ligament reconstruction: A systematic review. Knee Surgery, Sports Traumatology, Arthroscopy 2026. doi:10.1002/ksa.70517
This systematic review evaluated whether concomitant cartilage restoration modifies the clinical outcomes of medial patellofemoral ligament (MPFL) reconstruction. The analysis of 18 studies found no consistent additional clinical benefit from adding cartilage restoration procedures to MPFL reconstruction. Clinicians should not routinely perform cartilage restoration during MPFL reconstruction unless specifically indicated by other factors.
86. Pintore A, Fauré F, Pizzigallo C, et al. Magnetic Resonance Imaging Enables Precise Quantification of Patellar Height and Engagement in Patients Undergoing Tibial Tubercle Distalization Osteotomy for Objective Patellar Instability. Journal of ISAKOS 2026. doi:10.1016/j.jisako.2026.101177
This study utilized magnetic resonance imaging to precisely quantify patellar height and engagement in patients undergoing tibial tubercle distalization osteotomy for patellar instability. The findings indicate that MRI provides accurate measurements of patellar mechanics, which are critical for surgical planning and outcome assessment. This precision aids in optimizing surgical correction for objective patellar instability.
Osteotomy, Meniscus, and Cartilage Restoration (8)¶
12. Zeng C, Borim FM, Thorne D, et al. Increased tibial and meniscal slopes are risk factors for meniscal tears: A systematic review. Knee Surgery, Sports Traumatology, Arthroscopy 2026. doi:10.1002/ksa.70545
This systematic review and meta-analysis evaluated the association between tibial slope, meniscal slope, and meniscal bone angle with meniscal tear risk. Increased medial and lateral posterior tibial slopes were significantly associated with medial and lateral meniscal tears, respectively. These findings highlight tibial slope as a modifiable or assessable risk factor for meniscal pathology.
22. Gosnell GG, Sundaram V, Chen L, et al. Suture‐Only Fixation of Meniscal Allograft Is Associated With a Higher Reoperation Rate Than Bone Plug or Bone Bridge‐in‐Slot Fixation Techniques. Arthroscopy 2026. doi:10.1002/arj.70410
This retrospective study compared meniscus-specific reoperation rates among different fixation techniques used in meniscal allograft transplantation. Suture-only fixation was associated with significantly higher reoperation rates compared to bone plug or bone bridge-in-slot techniques. These results suggest that bone-based fixation methods may offer superior durability and lower revision risks in meniscal allograft transplantation.
26. Meyer LE, Bethell MA, Hurley ET, et al. Concomitant Procedures Around Cartilage Restoration Surgery Is Associated With Improved Outcomes and Decreased Failure Rates: A Systematic Review. Arthroscopy 2026. doi:10.1002/arj.70415
This systematic review evaluated the impact of concomitant alignment or meniscal surgery on outcomes following cartilage restoration procedures. The study found that adding osteotomy or meniscal allograft transplantation significantly reduced failure rates and improved functional scores compared to cartilage restoration alone. Clinically, this suggests that addressing associated mechanical issues during cartilage surgery enhances long-term success and patient outcomes.
31. Pineda T, Patel R, Vi AK, et al. Anterior cortical defects following infra‐tubercle slope‐reducing osteotomy show consistent remodelling without impairing union: A radiographic study with 12‐month follow‐up. Knee Surgery, Sports Traumatology, Arthroscopy 2026. doi:10.1002/ksa.70536
This radiographic study assessed anterior cortical defect remodelling following infra-tubercle slope-reducing osteotomy, finding substantial spontaneous bone regrowth over 12 months. The analysis showed that defect area decreased by approximately 60%, with remodelling occurring consistently without impairing union. These results suggest that anterior cortical defects created during this procedure heal reliably and do not negatively impact surgical outcomes.
33. Nejima S, Bonacic‐Bartolin P, Ball S, et al. Knee joint line obliquity alters lateral meniscal root tension, tibiofemoral subluxation and compartment‐specific contact pressures. Knee Surgery, Sports Traumatology, Arthroscopy 2026. doi:10.1002/ksa.70532
This biomechanical study measured meniscal root tension, subluxation, and contact pressures across varying knee joint line obliquities. It found that medial joint line obliquity significantly increases medial meniscal root tension and compartment-specific pressures, while lateral obliquity has the opposite effect. These findings suggest that surgical restoration of joint line alignment is critical for optimizing meniscal function and load distribution.
48. Dickschas J, Sendner T, Schubert I, et al. Anterior open wedge high tibial osteotomy for slope correction as a successful method in PCL insufficiency—Radiological and clinical results of a cohort study. Knee Surgery, Sports Traumatology, Arthroscopy 2026. doi:10.1002/ksa.70522
This cohort study evaluated the clinical and radiological outcomes of anterior open-wedge high tibial osteotomy for posterior tibial slope correction in patients with chronic PCL insufficiency. The procedure successfully increased the posterior tibial slope, resulting in improved subjective knee stability and functional scores at follow-up. This technique appears to be a viable surgical option for addressing posterior instability associated with reduced tibial slope.
63. Hashimoto Y, Aibara N, Yamasaki S, et al. Residual Midbody Meniscal Widths >13 mm Immediately After Surgery Decreased Faster and Had Greater Complication Rates in Discoid Lateral Menisci Treated With Saucerization and Repair. Arthroscopy 2026. doi:10.1002/arj.70378
The study evaluated residual meniscal width after saucerization and repair for discoid lateral menisci, finding that widths greater than 13 mm decreased faster and had higher complication rates. Maintaining a residual width of 9 to 13 mm appears optimal for minimizing complications while preserving function.
80. Fanourgiakis I, Pawelczyk J, Balfousias T, et al. Arthroscopic Medial Meniscus Allograft Transplantation Using a Bone-Bridge Technique Improves Clinical Outcomes with a Favorable Safety Profile. Journal of ISAKOS 2026. doi:10.1016/j.jisako.2026.101174
The study evaluated arthroscopic medial meniscus allograft transplantation using a bone-bridge technique, reporting improved clinical outcomes and a favorable safety profile. This technique offers a viable surgical option for patients requiring meniscal restoration with potentially reduced complications.
TKA Outcomes, Complications, and Patient Factors (10)¶
21. Tay ML, Rahardja R, Farrington WJ, et al. ‘Overall pain’ is strongly associated with patient satisfaction: An item‐level longitudinal analysis of the Oxford Knee Score in total and unicompartmental knee arthroplasty. Knee Surgery, Sports Traumatology, Arthroscopy 2026. doi:10.1002/ksa.70539
This longitudinal analysis of over 11,000 knee arthroplasty patients identified 'overall pain' as the item within the Oxford Knee Score most strongly and consistently associated with patient satisfaction across follow-ups up to 15 years. The study also established Patient Acceptable Symptom State thresholds for both total and unicompartmental knee arthroplasty. Clinically, these findings highlight that managing overall pain is the primary driver of long-term patient satisfaction and should be the central focus of postoperative care and outcome assessment.
37. Aljuboori SM, Petersen J, Christensen R, et al. Previous bariatric surgery was not associated with an increased risk of reintervention within 2 years after knee arthroplasty: A nationwide register‐based study from Denmark. Knee Surgery, Sports Traumatology, Arthroscopy 2026. doi:10.1002/ksa.70523
This nationwide register-based study assessed the risk of reintervention and mortality following knee arthroplasty in patients with prior bariatric surgery compared to matched controls. The analysis found no increased risk of reintervention within two years or mortality associated with prior bariatric surgery, regardless of body mass index at the time of arthroplasty. These results support the safety of knee arthroplasty in this patient population.
59. Güneş Z. Letter Regarding “Impact of Obesity on Daily Activity Following Total Knee Arthroplasty”. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2025.11.059
The author critiques a study on obesity and daily activity after total knee arthroplasty, citing methodological flaws such as a small morbidly obese subgroup and potential effect size inflation. These limitations raise concerns about the generalizability and statistical robustness of the reported findings.
94. Vosoughi F, Taghva Nakhjiri M, Ayati Firoozabadi A, et al. Depression as a Predictor of Postoperative Pain and Function After Total Knee Arthroplasty: A Meta-Analysis of Prospective Comparative Studies. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.07.008
A meta-analysis of prospective studies determined that while preoperative depression is associated with lower absolute postoperative pain and function scores after total knee arthroplasty, it does not significantly limit the magnitude of postoperative improvement. Clinicians should recognize that depressed patients still benefit substantially from surgery, though they may require additional support to manage expectations and pain.
95. Lee WS, Chung H, Lee J, et al. Does Cement Viscosity Influence 10-year Outcomes in Primary Total Knee Arthroplasty Under Standardized Surgical Technique?. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.07.015
This large retrospective study evaluated the impact of cement viscosity on 10-year outcomes in primary total knee arthroplasty, finding no significant association between viscosity levels and the risk of revision for aseptic loosening or radiolucent lines. These results suggest that cement viscosity is not a critical determinant of long-term implant survival when standardized surgical techniques are employed.
98. Mallett KE, Weinblatt AI, Ondek NT, et al. Finding the Sweet Spot: A Mixed-Effects Analysis of Four Tourniquet Strategies and Blood Conservation in 15,394 Primary Total Knee Arthroplasties. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.06.076
This retrospective study of 15,394 primary total knee arthroplasties compared four tourniquet strategies to determine their impact on blood loss and transfusion risk in the era of tranexamic acid. The analysis revealed that no-tourniquet and selective-use strategies resulted in greater hemoglobin drops and calculated blood loss compared to the incision-to-cementation reference group. These findings suggest that maintaining tourniquet inflation until cementation may offer superior blood conservation benefits over alternative strategies.
100. Pisharody VA, Nour G, Chowdary AR, et al. Projected Case Volume and Economic Burden of Knee Aseptic Loosening in Inpatient Total Knee Arthroplasty in the United States. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.07.032
This study characterized the incidence and economic burden of revision total knee arthroplasty for aseptic loosening in the United States from 2012 to 2022, projecting future trends to 2032. The results indicated a rising national volume of these revisions, accompanied by increasing average admission costs, despite a temporary dip during the pandemic. These projections underscore the growing financial strain on the healthcare system and highlight the need for strategies to mitigate aseptic loosening.
104. Telang SS, Wier J, Jones IA, et al. Dexamethasone is Associated with a Dose-Dependent Reduction in Venous Thromboembolic Complications following Total Knee and Hip Arthroplasty. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.07.018
This large-scale study investigated the association between perioperative dexamethasone dosing and venous thromboembolism (VTE) complications following total knee and hip arthroplasty. The analysis demonstrated a dose-dependent reduction in 90-day VTE risk, with higher doses of dexamethasone associated with significantly lower adjusted odds of VTE compared to no dexamethasone use. These results support the potential role of perioperative dexamethasone in mitigating inflammation-driven thrombogenesis and reducing VTE risk in arthroplasty patients.
105. Schneider AM, Granger C, King J, et al. Periarticular Injection Alone Provides Comparable Early Recovery to Combined Adductor Canal and Infiltration between the Popliteal Artery and Capsule of the Knee Blocks Following Total Knee Arthroplasty: A Prospective Randomized Trial. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.07.037
This prospective randomized trial compared early recovery outcomes between periarticular injection alone and combined adductor canal/IPACK blocks in 140 total knee arthroplasty patients. The study found comparable pain scores, opioid consumption, and functional recovery between the two groups, suggesting that regional blocks may not offer additional early benefits over periarticular injection alone. These findings support simplifying anesthesia protocols by potentially omitting nerve blocks without compromising initial postoperative recovery.
112. Carstens MF, Meissner N, Krych AJ, et al. Conversion of Patello-femoral Arthroplasty to Total Knee Arthroplasty: Survivorship, Function, and Predictors of Patellar Revision. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.07.046
This study evaluated survivorship and predictors of patellar revision following conversion of patellofemoral arthroplasty to total knee arthroplasty. The five-year survivorship free of revision was 89.2%, with progression of tibiofemoral osteoarthritis being the primary indication for conversion. Pre-conversion patellar alignment was not significantly associated with the need for patellar component revision, suggesting that patellar components can often be retained during conversion surgery.
