Overview

Arthroscopic techniques are increasingly integrated with osteotomy procedures across multiple joint regions, though their specific utility varies by anatomical site and clinical indication. In the knee, preoperative arthroscopic findings possess little, if any, predictive value for evaluating patients for high tibial osteotomy in the treatment of knee osteoarthritis [1]. While smaller studies including second-look arthroscopy provide the most convincing evidence for the efficacy of combined arthroscopy and osteotomy procedures [4], there is insufficient evidence that adjunctive arthroscopy with osteotomy yields superior results compared to osteotomy alone [2]. Conversely, in the ankle, the number of indications for anterior ankle arthroscopy is rising, and open surgery is increasingly replaced by arthroscopic surgery [91]. Among patients requiring reoperation for intra-articular defects, the average time to reoperation was nearly 5 months shorter for patients receiving arthroscopy than for patients who did not receive arthroscopy in lateral ankle ligament stabilization surgery [90].

In the hip, the combination of hip arthroscopy and periacetabular osteotomy is safe and effective, but clearer definitions for labral pathology and indications for repair or debridement are required [72]. Appropriate surgical indications based on preoperative intra-articular cartilage degeneration are paramount to achieving long-term success in periacetabular osteotomy [21]. Hip arthroscopy performed after prior pelvic osteotomy improves outcomes [2], and arthroscopic hip revision surgery for residual femoroacetabular impingement (FAI) leads to significantly improved outcome measures with appropriate indications and expectations [3]. Hip dysplasia may not be an absolute contraindication for isolated hip arthroscopy and may serve as a viable intervention with consideration of staged future periacetabular osteotomy (PAO) [11].

Arthroscopic fixation of tibial avulsion results in superior outcomes with a reduced incidence of complications compared to open techniques, although mini-open techniques demonstrated comparable efficacy in certain instances [23]. Arthroscopic femoral neck osteoplasty for femoroacetabular impingement has a lower major complication rate and decreased morbidity compared to open techniques, with equivalent patient outcomes at short-term and midterm follow-up [26]. More prospective studies comparing open and arthroscopic excision of ganglion cysts are needed to delineate if there is a true functional benefit [24].

Anatomy & Pathophysiology

Osseous and Pelvic Kinematics

Dynamic changes in pelvic tilt significantly influence the functional orientation of the acetabulum and must be considered [31]. In the context of high tibial osteotomy (HTO), three-dimensional kinematic analysis detects changes due to HTO that standard radiographs do not identify, including changes in the patellofemoral (PF) joint [36]. Opening-wedge high tibial osteotomy successfully prevents and slows the progression of knee osteoarthritis by changing the contact biomechanics [49].

For dysplastic hips, the authors recommend using biomechanical analysis as an adjunct to clinical decision-making [30]. From a biomechanical perspective, rotational acetabular osteotomy (RAO) was more effective in relieving hip joint stress compared with shelf procedure and Chiari osteotomy [58]. Conversely, despite reduction of the hip for long periods of time, acetabular remodeling did not occur in femoral varus-derotation osteotomy for spastic cerebral palsy [50].

Ligamentous and Capsular Integrity

The position of the femoral fovea can indicate hip instability and highly correlates with lesions of the ligamentum teres [38]. The Delta Angle (DA) can be reliably measured and serves as a valuable supportive parameter in the assessment of hip microinstability [38]. High rates of femoroacetabular impingement (FAI) morphologic characteristics are present in patients with hip instability [54].

Biomechanical evidence supports closure of the capsule after hip arthroscopy to reverse the significant effects of capsulotomy [32]. A substantial force is required to achieve and maintain hip distraction, with males requiring higher forces [40].

Biomechanical Goals and Complications

Painless restoration of normal hip biomechanics should be the goal of clinical correction of labral dysfunction through labral debridement, labral repair, or labral reconstruction [35]. Lumbopelvic stability and restoring appropriate hip biomechanics and muscle firing patterns are key to successful return to activity and sport [34].

In patients with risk factors such as altered biomechanics from knee procedures, hip pain or stiffness may indicate a stress fracture of the ipsilateral femoral neck, as early radiographs may be negative [37].

Classification

Arthroscopic Findings in Knee Osteotomy: Arthroscopic findings prior to high tibial osteotomy have little, if any, predictive value for evaluating patients for the procedure [1].

Meniscal Root Tear Classification: A novel arthroscopic classification of degenerative medial meniscus posterior root tears based on tear gap demonstrates that higher tear types (increasing displacement of the tear gap) are associated with higher meniscal extrusion, severe chondral wear, and greater severity of arthritis [56].

Meniscal Ramp Tear Classification: A surgically relevant classification system for medial meniscus ramp tears based on tear morphology allows for the evaluation of differing repair patterns and their effects on postoperative clinical outcomes [84].

Hip Pathology Classification: Arthroscopic classification of intra-articular hip pathology demonstrates at best moderate interrater reliability, even among high-volume hip arthroscopists [74].

Patient Selection Criteria: Arthroscopic surgery in patients over 50 years of age might be beneficial if classified as Tönnis grade 0 preoperatively and/or classified as Outerbridge grade II in arthroscopic findings [71].

Complication Rate Comparison: Complication rates after hip arthroscopy are in line with complication rates after open surgical dislocation when using the same classification system [79, 80].

Clinical Presentation

History: Preoperative arthroscopic findings have little, if any, predictive value in evaluating patients for high tibial osteotomy [1]. For femoroacetabular impingement syndrome (FAIS), untreated symptoms lasting 2 years or longer before arthroscopic management correlate with significantly worse patient-reported outcomes and higher reoperation rates at 2 years post-surgery compared to shorter symptom durations [12]. In adolescents, arthroscopic management of FAI reports favorable outcomes that are more than comparable to those of an adult population [60]. Hip arthroscopy performed after prior pelvic osteotomy improves outcomes [2].

Inspection and Diagnostic Utility: Routine use of arthroscopy has led to the identification of previously unrecognized pathological conditions and provided significant new information about traditional problems [10]. Arthroscopy may be necessary to substantiate the diagnosis of pigmented villonodular synovitis in the hip and to assess and address other accompanying damage in these cases [8]. Even in the absence of radiographic osteoarthritis, patients with femoroacetabular impingement and normal radiographic joint space width have a probability of extensive articular damage [14]. A clinical diagnosis of hip osteoarthritis was found in approximately 22% of young patients undergoing hip arthroscopy for FAIS within 2 years [59].

Palpation and Special Tests: Arthroscopic intervention is an appropriate modality for addressing anterior labral tears with posterior hip subluxation or dislocation in patients with continued symptoms [5]. Arthroscopic decompression of a symptomatic anterior inferior iliac spine (AIIS) deformity is a reproducible procedure that can provide excellent outcomes at short-term follow-up [16]. Arthroscopic excision of acetabular osteoid osteoma has been successfully performed in a 7-year-old patient [15]. Wrist arthroscopy requires accurate placement of portals and small instrumentation to examine, probe, and treat intra-articular abnormalities [17].

Management and Outcomes: Arthroscopic management of femoroacetabular impingement (FAI) results in significant improvement in outcomes measures and the 'impingement' sign at early term follow-up [13]. The arthroscopic technique for chronic lateral epicondylitis offers advantages of earlier return to work, a shorter recovery period, and the ability to inspect the joint and treat coexisting pathologies compared to open treatment [19]. Knee arthroscopy is effective in treating patients with symptomatic osteoarthritis and mechanical symptoms using a novel synthetic acellular meniscal scaffold, with 76% of patients reporting good and excellent results [62]. Judicious use of arthroscopic surgery is appropriate for managing symptomatic coexisting disease or abnormality in the presence of osteoarthritis or degeneration [39].

Complications and Decision Axes: Knee arthroscopy is not a benign procedure; surgeons should be aware of procedure complexity, patient factors, and regional differences to reduce complications [55]. Surgeons should carefully assess patients with failed hip arthroscopy to identify mild to moderate dysplasia deformities that were not addressed with arthroscopic treatment [61]. There is insufficient evidence that adjunctive arthroscopy with osteotomy yields superior results compared to osteotomy alone [2]. Available information is not sufficient to support one treatment modality over another for femoroacetabular impingement, and the answers regarding the interchangeability of arthroscopy and surgical dislocation for this condition remain unclear [18].

Investigations

Plain radiography: Preoperative arthroscopic findings prior to high tibial osteotomy have little, if any, predictive value in evaluating patients for this procedure [1]. In patients with femoroacetabular impingement and normal radiographic joint space width, the probability of extensive articular damage exists even in the absence of radiographic osteoarthritis [14]. Arthroscopy is not recommended for hip femoroacetabular impingement patients with evolved osteoarthritis [25]. Post-surgical radiographic and anatomical evidence of capsular defects exists in a select group of patients following hip arthroscopy [106]. The progression of osteoarthritis after rotational acetabular osteotomy was not detected for at least twenty years in most hips with either pre-osteoarthritis or initial osteoarthritis [116].

MRI: Routine preoperative magnetic resonance imaging for hip arthroscopy is unnecessary for patients with typical symptoms and findings, as it delays surgical intervention and increases costs without altering surgical decision-making [112]. Preoperative magnetic resonance imaging delays time to hip arthroscopy in patients aged ≤40 years with femoroacetabular impingement syndrome [98]. Gadolinium intra-articular contrast magnetic resonance imaging is not required for every patient undergoing hip arthroscopy [105]. In patients with a normal MRI without contrast and a positive response to an intra-articular injection who failed conservative management, there is a 98% chance of intra-articular hip pathology being discovered on hip arthroscopy [103]. Arthroscopy may be necessary to substantiate the diagnosis of pigmented villonodular synovitis in the hip and to assess and address other accompanying damage [8]. Magnetic resonance imaging at 1 year after surgery demonstrated residual tear evidence for all patients evaluated for meniscus tear repair healing using in-office needle arthroscopy [115].

CT: Contrast magnetic resonance imaging plus computed tomography with 3-dimensional reconstruction are essential for patients requiring revision hip arthroscopy [105].

Other Considerations: Thorough preoperative evaluation of radiographs and advanced imaging is encouraged for all patients being considered for hip arthroscopy, particularly in cases of iatrogenic hip instability treated with periacetabular osteotomy [66]. Arthroscopically assisted procedures may identify concomitant injuries not initially seen on imaging or when a complete imaging evaluation is not available [104]. More than one half of patients undergoing revision hip arthroscopy had MRI and intraoperative evidence of capsular incompetency [113]. Available information is not sufficient to support one treatment modality over another regarding the interchangeability of hip arthroscopy and surgical dislocation for femoroacetabular impingement [18]. Smaller studies that include second-look arthroscopy provide the most convincing evidence for the efficacy of combined procedures [4].

Specific Arthroscopic Indications: Arthroscopic intervention is an appropriate modality for addressing anterior labral tears with posterior hip subluxation or dislocation in patients with continued symptoms [5]. Arthroscopic excision of acetabular osteoid osteoma has been successfully performed in a 7-year-old patient, representing the youngest reported case for this condition [15]. Arthroscopic decompression of a symptomatic anterior inferior iliac spine deformity is a reproducible procedure that can provide excellent outcomes at short-term follow-up [16]. Wrist arthroscopy requires accurate placement of portals and small instrumentation to examine, probe, and treat intra-articular abnormalities [17].

Treatment

Non-Operative

Nonoperative treatment serves as the first-line intervention for most femoroacetabular impingement (FAI) patients and should not be abandoned in favor of early surgery [20]. Hip arthroscopy is an appropriate viable option for FAI only after failure to improve after a full course of physical therapy is established [20]. For posterior ankle pathology, conservative treatment is the initial approach, with arthroscopy indicated when conservative measures fail [82]. In hallux valgus, nonoperative treatment cannot correct the deformity but can help control symptoms [86].

Operative

Indications: The main indication for hip arthroscopy is FAI [57]. For adolescents with open physes, a non-physeal-sparing arthroscopic approach is safe and effective with no evidence of clinically relevant complication of growth arrest-related deformity or physeal instability at minimum 1 year follow-up [107]. Osteotomy should be the first operation considered in a young individual with osteoarthritis of the hip, performed before there is collapse of the head or reduction of the range of flexion below 90 degrees [123]. Appropriate surgical indications based on preoperative intra-articular cartilage degeneration are paramount to achieving long-term success in periacetabular osteotomy (PAO) [21]. Hip dysplasia may not be an absolute contraindication for isolated hip arthroscopy and may serve as a viable intervention with consideration of staged future periacetabular osteotomy (PAO) [11].

Surgical Approach / Technique: Arthroscopic management of FAI results in significant improvement in outcomes measures and the 'impingement' sign at early term follow-up [13]. Favorable outcomes of arthroscopic management of FAI are reported in adolescents compared with an adult control group [81]. Hip arthroscopy for FAI produced clinically meaningful outcomes in both competitive athletes and nonathletes [100]. The arthroscopic method for femoroacetabular impingement had surgical outcomes equal to or better than open dislocation or mini-open methods with a lower rate of major complications when performed by experienced surgeons [6]. With careful selection and modern techniques, patients with dysplasia can benefit significantly and durably from arthroscopic labral repair at midterm follow-up [53]. Combined one-stage treatment of non-arthritic hip dysplasia with hip arthroscopy and PAO obtained good clinical and radiological outcomes [102]. Arthroscopy provides a tool to treat intra-articular hip pathology secondary to dysplasia while improving bony coverage/alignment with periacetabular osteotomy through a specialized team approach [51]. Hip arthroscopy after prior pelvic osteotomy improves outcomes [2]. There is insufficient evidence that adjunctive arthroscopy with osteotomy yields superior results compared to osteotomy alone [2].

Implant Selection: Osteotomy fixation with 3 proximal and 3 distal screws was associated with osteotomy healing in opening-wedge high tibial osteotomy [118]. Arthroscopic stabilization with resorbable devices for glenohumeral stabilization is a highly reliable procedure, though not devoid of complications such as anterior glenoid rim fracture [109]. Spherical varus rotational osteotomy of the femur using a navigation system is an effective, less invasive alternative to trochanteric rotational osteotomy (TRO) for patients with extensive necrosis who would have otherwise required rotational osteotomy [47]. Modified Salter osteotomy is technically more difficult than the regular Salter osteotomy and is not intended to routinely replace it [29].

Alignment / Balancing Strategy: The role of osteotomy in the contemporary surgical treatment of osteoarthritis may be better defined by understanding its mechanical and cellular basis [7]. The arthroscopic findings prior to high tibial osteotomy appeared to have little, if any, predictive value in evaluating patients for this procedure [1].

Pain Management: Intraarticular injections of local anaesthetics (ropivacaine) provide an alternative and effective solution in pain control after knee arthroscopy [64]. Pericapsular injection is a safe intervention that allows for efficient postoperative analgesia for patients undergoing hip arthroscopy [70]. A preoperative femoral nerve block is a relatively safe procedure that may decrease the requirement for intraoperative morphine while providing effective postoperative pain control in patients undergoing hip arthroscopic surgery [88].

Adjuncts: Additional complications relating to surgical technique, such as suture anchors and femoral osteoplasty, arose as more complex procedures were performed [119]. Risk factors for heat-related complications from radiofrequency and electrocautery devices include leakage of arthroscopy fluid, use of a thermal device, intra-articular anesthetics/pain pumps, and performing specific surgical procedures [93]. Periportal capsulotomy during hip arthroscopy resulted in significant clinical improvement and no postoperative instability at 1 and 2 years after surgery [121].

Other Considerations: Arthroscopic resection of synovial plica of the elbow is effective and safe if conservative treatment fails [96]. Arthroscopic management of pigmented villonodular synovitis of the knee provides relief of pain [111]. Arthroscopic removal of troublesome screws in slipped capital femoral epiphysis can successfully be achieved, affording the benefits of minimally invasive surgery and the ability to address concomitant hip pathology [122]. Arthroscopic locking plate removal after proximal humeral fractures is recommended for all surgeons familiar with arthroscopic surgery [41]. Arthroscopic iliopsoas lengthening is a safe and effective treatment for anterior iliopsoas impingement after total hip arthroplasty, providing considerable pain relief in 80% of patients and helping avoid major revision arthroplasty surgery in 100% of cases [22]. Surgeons should view cementless stem removal systems as valuable adjuncts rather than replacements for traditional osteotomies, and must remain vigilant in case selection and intraoperative execution [89]. Suggested guidelines for the practice of arthroscopic surgery emphasize the need for appropriate training, privileges, and performance review by the Arthroscopy Association of North America [67, 68, 69]. There is no single 'right way' to be an expert arthroscopist, as varied approaches and techniques among luminaries all yield superb patient outcomes [45].

Complications

Thromboembolism: The incidence of symptomatic postoperative venous thromboembolism (VTE) following hip arthroscopy is low [108]. The rate of short-term complications, including deep vein thrombosis (DVT) and pulmonary embolism (PE), is low after hip arthroscopy [99]. A systematic review of 92 studies and more than 6,000 patients reported a major complication rate of 0.58% [154]. The low incidence of VTE events (2.0%) after hip arthroscopy suggests that prophylaxis may not be necessary in low-risk patients, although the true rate may be under-reported [114]. However, thromboembolic complications do occur after elective hip arthroscopy [120]. Significant risk factors for postoperative VTE include obesity, smoking, age greater than 45 years, oral contraceptive use, and malignancy [133], [134]. Obese patients undergoing hip arthroscopy are at a significantly increased risk of postoperative complications such as DVTs and worsened hip pain [136]. Single-dose intravenous tranexamic acid does not increase the venous thromboembolic rate or complication rate during hip arthroscopy [137]. Distinct differences in thrombosis risk per person exist after knee arthroscopy [110]. Patients undergoing closed-wedge high tibial osteotomy are at risk of postoperative VTE [140].

Infection (PJI): The overall rate of surgical site infections is low following hip arthroscopy [155]. Periprosthetic joint infection has incidence rates of 0.4% to 2% after primary total knee replacement [135].

Other Considerations: Arthroscopic surgery for femoroacetabular impingement has surgical outcomes equal to or better than open dislocation or mini-open methods, with a lower rate of major complications when performed by experienced surgeons [6]. Arthroscopic femoral neck osteoplasty for femoroacetabular impingement has a lower major complication rate and decreased morbidity compared to open techniques, with equivalent patient outcomes at short-term and midterm follow-up [26]. Arthroscopy has a low risk of complications and low morbidity [161]. In an analysis of 2,640 arthroscopic procedures, the complication rate was 8.2% [127]. Arthroscopic and related surgery has a low complication rate, but surgeons must learn from complications through careful review and study of etiology and prevention [139]. Complications in elbow arthroscopy are higher than in other joint arthroscopies but can be minimized [157]. Overall rates of complication were lower following arthroscopic approaches compared to open debridements in a cohort of elbow arthroscopy surgeons [144]. Arthroscopy for isolated tibial avulsion results in superior outcomes with a reduced incidence of complications compared to open fixation, although mini-open techniques may demonstrate comparable efficacy in certain instances [23].

Revision and Conversion Outcomes: Arthroscopic hip revision surgery for residual FAI leads to significantly improved outcome measures with appropriate indications and expectations [3]. Repeat revision hip arthroscopy results in clinically significant improvement in patient-reported outcomes, but outcomes are similar to first-time revision cases and inferior to those obtained following primary surgeries [130]. Revision hip arthroscopic surgery resulted in an improvement in outcome in the first 3 years after revision, with significant improvement only in the first 2 years [156]. The reoperation rate after revision hip arthroscopy is 5% within 2 years, including further arthroscopy or conversion to hip arthroplasty [149]. In primary hip arthroscopy, 90-day adverse events were low at 1.28%, and the 5-year secondary surgery rate was 4.9% [150]. There was a significant decline in revision rates over time after hip arthroscopy for femoroacetabular impingement syndrome [142]. Rates of total hip arthroplasty after hip arthroscopy were similar to prior studies, whereas the rates of revision hip arthroscopy were higher [158]. A lower rate of conversion to total hip arthroplasty was seen in patients undergoing capsulotomy repair compared to nonrepair during hip arthroscopy for femoroacetabular impingement with labral repair [159]. A time interval of less than 12 months or greater than 12 months between staged bilateral hip arthroscopies did not affect clinical outcomes and revision rate [151].

Specific Procedures and Populations: Arthroscopic iliopsoas lengthening for anterior iliopsoas impingement after total hip arthroplasty has minimal complications, provides considerable pain relief in 80% of patients, and helps avoid major revision arthroplasty surgery in 100% of cases [22]. Arthroscopic labral reconstruction of the hip is associated with low rates of complications, revision surgery, and progression of arthritis, although graft types and concomitant procedures confound results [141]. Segmental and circumferential acetabular labral reconstruction have comparable outcomes, with no demonstrated clinical superiority of either technique due to study heterogeneity and low level of evidence [148]. Patients with borderline dysplastic hips achieve statistically similar clinical outcomes after isolated hip arthroscopy compared with control subjects without dysplasia at short-term follow-up [143]. Concomitant peri-acetabular osteotomy and arthroscopy, as well as isolated arthroscopy with capsular plication for borderline dysplasia, show favorable results with similar rates of revision and conversion to arthroplasty at minimum 2-year follow-up [146]. A high incidence of significant articular damage is observed at the time of arthroscopic intervention for femoroacetabular impingement [160]. The annual incidence of total knee arthroplasty following arthroscopic surgery for osteoarthritis is 2.46% (95% CI 1.68–3.25%) [162]. Further studies are required to investigate the degree of patient-reported outcome improvement and long-term arthroscopy revision and total hip arthroplasty conversion rates in smokers undergoing hip arthroscopy [145]. Harms reporting is inadequate in most systematic reviews concerning hip arthroscopy [152].

Recovery

Light activity (weeks): Patients may return to driving two weeks postoperatively from a right-sided hip arthroscopy procedure [63]. Braking parameters normalize to the preoperative state at one week after simple arthroscopy and two weeks after femoroacetabular impingement (FAI) surgery [94]. The arthroscopic technique for chronic lateral epicondylitis offers advantages of an earlier return to work and a shorter recovery period compared to open techniques [19].

Full activity (months): The majority of improvement after hip arthroscopy for FAI occurs within three months after surgery [101]. Certain outcomes, such as returning to sport, quality of life, and pain, can continue to improve through two years after hip arthroscopy for FAI [101]. Patients with untreated FAIS-related symptoms lasting two years or longer before arthroscopic management had significantly worse patient-reported outcomes and higher rates of reoperation at two years after surgery compared with those with shorter preoperative symptom duration [12]. Most patients achieved successful clinically meaningful outcomes after arthroscopic repair of circumferential labral tears at a mean follow-up of approximately five years [83]. The majority of patients achieve clinically significant outcome improvement at five-year follow-up after arthroscopic FAIS surgery [97].

Complete recovery / outcome plateau (months): Master athletes undergoing primary hip arthroscopy for FAI achieve comparable patient-reported outcomes, achievement of clinically significant outcomes, and reoperation-free time-dependent survivorship to nonmaster athletes at long-term follow-up (mean ten years) [117]. In addition to low recurrence rates and good functional outcomes in >90% of patients, 98% returned to sport activity after arthroscopic treatment of posterior shoulder instability [124]. High-level athletes competing in flexibility sports demonstrated similar improvements in outcome scores and comparable rates of return to sports at minimum two-year follow-up after hip arthroscopy [128]. Revision hip arthroscopy in high-level athletes showed significant improvement in functional scores and a high rate of successful outcomes, though they achieved lower postoperative PRO scores and attempted to return to sport at lower rates compared to primary surgery [129]. Patients who underwent revision posterior labral repair experienced improvements in outcomes and a decrease in pain on average, but exhibited rates of return to active-duty and sports that lagged behind those who underwent a primary procedure [85].

Rehabilitation protocol: Closed intramedullary derotational osteotomy and hip arthroscopy for cam FAI from femoral retroversion permits rapid institution of weight-bearing ambulation and an early rehabilitative program [75]. An accelerated rehabilitation program can be practiced for fully arthroscopic repair of chronic lateral instability of the ankle, resulting in fewer complications [46]. Patients following a comprehensive five-phase rehabilitation protocol after hip arthroscopy for FAI demonstrated satisfactory clinical and functional outcomes [76]. Similar rehabilitation protocols are supported for patients with and without GLAD lesions following arthroscopic stabilization for first-time anterior shoulder instability [77]. A physical therapy regimen prior to surgical intervention for rotator cuff tears with adhesive capsulitis may not be necessary [73].

Functional milestones: Arthroscopic hip revision surgery for residual FAI leads to significantly improved outcome measures with appropriate indications and expectations [3]. Smaller studies that include second-look arthroscopy provide the most convincing evidence for the efficacy of combined procedures [4]. The objectives of surgical treatment for FAI are to improve symptoms and prevent or slow the progression of osteoarthritis by improving joint clearance [44]. Arthroscopic correction of FAI can result in significant improvement but does not invariably result in full restoration of function due to the possibility of residual symptoms from cumulative damage [147]. Primary repair of the acetabular labrum showed good clinical results with favorable outcomes and evidence of good healing, even among patients who required repeat arthroscopy [153]. The early clinical outcome of arthroscopic offset restoration and debridement is good in patients with no or only mild osteoarthritis [138]. Arthroscopic Latarjet with capsular repair resulted in a clinically meaningful change in patient's functional outcome for recurrent anterior glenohumeral instability [131]. The magnitudes of improvement in patient-reported outcomes after primary hip arthroscopy in athletes older than age 40 were comparable between master athletes and controls, with master athletes meeting clinically meaningful thresholds at higher rates and having higher arthroplasty-free survivorship [126].

Other Considerations: Nonoperative treatment remains the first line of treatment for most FAI patients, including adolescents, and should not be abandoned in favor of early surgery [20]. Hip arthroscopy is an appropriate viable option only after failure to improve after a full course of physical therapy is established [20]. More prospective studies comparing open and arthroscopic excision of ganglion cysts are needed to delineate if there is a true functional benefit [24].
