Abstract
PURPOSE OF REVIEW Gluteus medius and minimus tears, or hip abductor tendon tears, are increasingly identified as a source of lateral hip pain. Once underappreciated and undertreated, they are now recognized as a cause of greater trochanteric pain syndrome and a pathology amenable to both nonoperative and operative modalities. This review summarizes relevant anatomy, clinical presentation, and treatment options for gluteus medius tears, focusing on surgical options. RECENT FINDINGS When surgical intervention is indicated, repair, reconstruction, or tendon transfer may be considered. Open and endoscopic repair techniques demonstrate similar outcomes with improvements in patient-reported outcomes and low complication and retear rates for both partial and full thickness tears. Variations in fixation construct and graft augmentations have been described, though clinical evidence remains limited to support specific techniques. Gluteus maximus transfer via open approach is a salvage option for the severely atrophied, retracted, or revision gluteus tendon; however, persistent limitations in abduction strength and gait abnormalities are common. Emerging evidence continues to evolve our understanding of surgical decision-making for gluteus tendon tears. The current literature supports either open or endoscopic repair techniques and open tendon transfer as a salvAage option. Further study is needed to determine the optimal fixation construct, the role of graft augmentation, and patient-related factors that influence postoperative outcomes.

Gluteus Repair Yields Satisfactory Clinically Significant Outcome Achievement by 1 Year in Mostly Partial-Thickness Tears With Preoperative Hip Abduction Weakness Associated With Delayed Achievement. Arthroscopy 2024:S0749-8063(24)00231-7. [PMID: 38508287 DOI: 10.1016/j.arthro.2024.02.044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Revised: 02/21/2024] [Accepted: 02/29/2024] [Indexed: 03/22/2024]
Abstract
PURPOSE To define the time to achievement of clinically significant outcomes (CSOs) after primary gluteus medius and/or minimus (GM) repair and to identify factors associated with delayed CSO achievement. METHODS Patients who underwent primary GM repair between January 2012 and June 2021 with complete preoperative, 6-month, 1-year, and 2-year Hip Outcome Score-Activities of Daily Living (HOS-ADL) were retrospectively identified. Cohort-specific minimal clinically important difference (MCID) and patient acceptable symptom state (PASS) were calculated. The time to achievement of MCID and PASS was analyzed using Kaplan-Meier survival analysis. Median time to MCID and PASS achievement was recorded. Multivariate stepwise Cox regressions were used to identify factors associated with delayed CSO achievement. RESULTS Fifty GM repairs were identified (age 59.4 ± 9.7 years, body mass index 27.9 ± 6.2, 94% female). Tears were grade 1 in 39 cases, grade 2 in 7 cases, and grade 3 in 4 cases. Endoscopic repair was performed in 35 cases, and open repair was performed in 15 cases. Labral debridement and repair were each performed in 15 cases. Median time to CSO achievement was 5.7 months for MCID and 11.0 months for PASS. The 2-year cumulative probability of MCID and PASS achievement was 92.7% and 66.7%, respectively. Preoperative hip abduction weakness on physical examination was associated with delayed achievement of MCID (hazard ratio 2.27, confidence interval 1.067-7.41, P = .039) and PASS (hazard ratio 3.89, confidence interval 1.341-11.283, P = .012). CONCLUSIONS This study demonstrated that in patients undergoing repair of primarily grade 1 GM tears, most achieved MCID by 6 months, and more than one half achieved PASS by 12 months. Preoperative hip abduction weakness on physical examination was associated with delayed CSO achievement. LEVEL OF EVIDENCE Level IV, retrospective case series.

The Gluteus-Score-7 Predicts the Likelihood of Both Clinical Success and Failure Following Surgical Repair of the Hip Gluteus Medius and/or Minimus. Arthroscopy 2024; 40:343-351.e4. [PMID: 37207918 DOI: 10.1016/j.arthro.2023.03.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Revised: 02/20/2023] [Accepted: 03/19/2023] [Indexed: 05/21/2023]
Abstract
PURPOSE To identify patient preoperative history, examination, and imaging characteristics that increase the risk of postoperative failure of gluteus medius/minimus repair, and to develop a decision-making aid predictive of clinical outcomes for patients undergoing gluteus medius/minimus repair. METHODS Patients from 2012 to 2020 at a single institution undergoing gluteus medius/minimus repair with minimum 2-year follow-up were identified. MRIs were graded according to the "three-grade" classification system: grade 1: partial-thickness tear, grade 2: full-thickness tears with <2 cm of retraction, grade 3: full-thickness tears with ≥2 cm retraction. Failure was defined as undergoing revision within 2 years postoperatively or not achieving both a cohort-calculated minimal clinically important difference (MCID) and responding "no" to patient acceptable symptom state (PASS). Inversely, success was defined as reaching both an MCID and responding "yes" to PASS. Predictors of failure were verified on logistic regression and a predictive scoring model, the Gluteus-Score-7, was generated to guide treatment-decision making. RESULTS In total, 30 of 142 patients (21.1%) were clinical failures at mean ± SD follow-up of 27.0 ± 5.2 months. Preoperative smoking (odds ratio [OR], 3.0; 95% confidence interval [CI], 1.0-8.4; P = .041), lower back pain (OR, 2.8; 95% CI, 1.1-7.3; P = .038), presence of a limp or Trendelenburg gait (OR, 3.8; 95% CI, 1.5-10.2; P = .006), history of psychiatric diagnosis (OR, 3.7; 95% CI, 1.3-10.8; P = .014), and increased MRI classification grades (P ≤ .042) were independent predictors of failure. The Gluteus-Score-7 was generated with each history/examination predictor assigned 1 point and MRI classes assigned corresponding 1-3 points (min 1, max 7 score). A score of ≥4/7 points was associated with risk of failure and a score ≤2/7 points was associated with clinical success. CONCLUSIONS Independent risk factors for revision or not achieving either MCID or PASS after gluteus medius and/or minimus tendon repair include smoking, preoperative lower back pain, psychiatric history, Trendelenburg gait, and full-thickness tears, especially tears with ≥2 cm retraction. The Gluteus-Score-7 tool incorporating these factors can identify patients at risk of both surgical treatment failure and success, which may be useful for clinical decision-making.

Abstract
Background Studies have indicated a correlation between patients presenting with decreased gluteus medius function and a history of lumbar pathology (LP). However, literature investigating the relationship between the prevalence of lumbar pathology in patients with gluteus medius tears is lacking. The purpose of this study is to determine if patients undergoing repair for gluteus medius tears have concomitant lumbar pathology. Materials and methods Patients aged 18-80 who underwent endoscopic gluteus medius repair by one fellowship-trained surgeon between May 2016 and May 2020 for peritrochanteric pain/tenderness, abductor weakness, and MRI findings consistent with a gluteus medius tear were identified. Pre-operative and post-operative data were gathered using the Visual Acuity Scale (VAS), and post-operative data was gathered using the Abbreviated International Hip Outcome Tool (iHOT-12) and Hip Outcome Score - Activities of Daily Living (HOS-ADL). Outcomes were compared between patients with and without a history of lumbar pathology. Results Of 23 hips, 19 (82.6%) presented with a prior history of lumbar pathology. Twenty (87.0%) patients identified were female. A total of 19 hips were included with completed PROM scores. Patients with lumbar pathology had similar pre and post-operative patient reported outcomes. Conclusions This study demonstrates a high incidence of lumbar pathology in patients presenting for operative gluteus medius tears, which may suggest an association between lumbar disease and the development of gluteus medius weakness and tears.

Abstract
PURPOSE To evaluate 10-year patient-reported outcome (PRO) scores following endoscopic surgery for gluteus medius partial and full-thickness tears with concomitant hip arthroscopy for labral tears and/or femoroacetabular impingement syndrome (FAIS). METHODS Prospectively collected data on patients followed for a minimum of 10 years after endoscopic gluteus medius repair with concomitant hip arthroscopy performed by a single surgeon were retrospectively analyzed. Patients with preoperative and 10-year follow-up for the following PROs were included: modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale (HOS-SSS), and Visual Analog Scale (VAS) score for pain. RESULTS There were 13 patients eligible for inclusion, 11 (84.6%) of whom had 10-year follow up, with a mean of 127.6 months (range: 120.0-140.2 months). The group consisted of 10 females (90.9%) and one male (9.1%) with a mean age at surgery of 60.1 years (range: 46.2-74.8 years). PRO scores improved from preoperative to 10-year follow-up as follows: mHHS from 60.4 to 88.0 (P = .011); NAHS from 50.1 to 90.6 (P < .001); HOS-SS from 37.5 to 85.1 (P = .001); and VAS from 4.8 to 1.2 (P = .006). Mean patient satisfaction rating was 8.3. Patients achieved PASS and MCID for mHHS and HOS-SSS at a rate of 81.8%. There was no significant decline in PROs or satisfaction between 2, 5, and 10 years postoperatively. All patients underwent concomitant hip arthroscopy and labral treatment (debridement or repair). One patient, who had arthroscopic findings of acetabular and femoral outerbridge grade 4 lesions, subsequently underwent total hip arthroplasty; however, the GM was assessed during the THA, and it was verified that the repair was intact. There were no clinical failures, secondary operations, or complications. CONCLUSIONS Endoscopic repair of gluteus medius tears is a safe procedure with favorable and durable long-term outcomes at minimum 10-year follow-up.

Abstract
Purpose To evaluate the effect of hip flexion and rotation on excursion of the gluteus medius (Gmed) and minimus (Gmin) myotendinous unit. Methods Seven hips from 4 cadaveric specimens (males, 68.5 ± 18.3 years old) were dissected to isolate the Gmed posterior and lateral insertions and the Gmin proximal and distal insertions. Sutures were placed from tendon insertions through origins created in the iliac fossa to simulate the myotendinous unit. A load of 10N was applied. Myotendinous excursion was measured at 10° hip extension and 0°, 45°, and 90° of hip flexion in neutral rotation, and from maximum internal and external rotation in 90° flexion. The amount of abduction and rotation was also measured at each flexion position with 20N applied to each tendon. Repeated-measures analysis of variance with Tukey post hoc was used for statistics. Results Gmed-lateral excursion ranged from 2.4 ± 0.4 mm in 10° of hip extension to 23.0 ± 1.5 mm in 90° of flexion (P < .001), and Gmed-posterior excursion ranged from 0.92 ± 0.5 mm in 10° of extension to 38.1 ± 1.1 mm in 90° of flexion (P < .001). Gmin excursion shortened with hip flexion from 4.2 ± 0.3 mm in 10° of extension to -0.2 ± 1.5 mm in 90° of flexion (Gmin-prox: P = .525, Gmin-distal: P < .001). At 90° flexion from maximum internal to maximum external rotation, Gmin-distal and proximal demonstrated a 92.6% and 51.3% increase in excursion, respectively (P < .001). Gmed-lateral and Gmed-posterior demonstrated 49.4% and 23.1% increase in excursion with external rotation, respectively (P < .001). Conclusions The Gmed myotendinous unit undergoes significant excursion with hip flexion, whereas both Gmed and Gmin had significant excursion with femoral external rotation in 90° flexion. Clinical Relevance It is important to understand whether active or passive hip flexion or rotation in the early postoperative period causes excessive strain to an abductor tendon repair. We found that consideration should be given to limit flexion after Gmed repair and external rotation after Gmed or Gmin repairs.

Three-Grade Magnetic Resonance Imaging-Based Gluteus Medius and/or Minimus Tear Classification System Provides Excellent Inter-Rater Reliability. Arthrosc Sports Med Rehabil 2023; 5:e773-e782. [PMID: 37388882 PMCID: PMC10300604 DOI: 10.1016/j.asmr.2023.04.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Accepted: 04/08/2023] [Indexed: 07/01/2023] Open
Abstract
Purpose To develop a magnetic resonance imaging (MRI)-based classification system integrating tear characteristics including tear thickness (partial vs full) and tear retraction (less than or greater than 2 cm) for gluteus medius and/or minimus tears and to determine the inter-rater reliability of this MRI-based classification for gluteus medius and/or minimus tears. Methods Patients who underwent primary endoscopic or open repair of gluteus medius and/or minimus tears between 2012 and 2022 were identified to be included in the review of 1.5-T MRI scans. One hundred MRI scans were randomized for review by 2 orthopaedic surgeons and evaluated for tear thickness (partial vs full), extent of retraction, and degree of fatty infiltration according to an applied Goutallier-Fuchs (G-F) classification. Tears were also graded according to the 3-grade MRI-based classification system as follows: grade 1, partial-thickness tears; grade 2, full-thickness tears with less than 2 cm of retraction; grade 3, full thickness with 2 cm or more retraction. Inter-rater reliability was calculated by absolute and relative agreement using Cohen's kappa (κ). Significance was defined by P value <.05. Results In total, 221 patients were identified, and after application of exclusion criteria and randomization, 100 scans were evaluated. The 3-grade classification system demonstrated high absolute agreement (88%) comparable to the absolute agreement of the G-F classification (67%). The 3-grade classification system demonstrated substantial inter-rater reliability (κ = 0.753), whereas the G-F classification demonstrated moderate inter-rater reliability (κ = 0.489). Conclusions The proposed 3-grade MRI-based classification system for gluteus medius and/or minimus tears demonstrated substantial inter-rater reliability, comparable with that of the applied G-F classification. Clinical Relevance It is important to understand how gluteus medius and/or minimus tear characteristics impact postoperative outcomes. The 3-grade MRI-based classification incorporates tear thickness and amount of retraction that can complement previous classification systems to give the provider and patient more information when considering treatment options.

Abstract
PURPOSE The primary purpose of this study was to systematically review the literature on intraoperative findings during endoscopic treatment for greater trochanteric pain syndrome (GTPS). Secondary outcomes were preoperative imaging findings and postoperative functional outcome measures. METHODS Medline, PubMED, and Embase databases were searched from inception (1946, 1966, and 1974, respectively), to July 15, 2021, for records reporting intraoperative findings during endoscopic surgery for GTPS. Studies of Level I-IV evidence were eligible. All studies were assessed for quality using the Methodological Index for Non-Randomized Studies (MINORS) score. RESULTS Sixteen studies met the inclusion criteria. Most patients underwent endoscopic greater trochanteric bursectomy with repair of the gluteal tendons. Intraoperative conditions reported were gluteal tendon tears usually involving the gluteus medius tendon, labral tears, and chondral lesions. Three studies reported an average of 9% of patients who subsequently underwent conversion to total hip arthroplasty. Pain was assessed using the visual analog scale, and functional outcome measures were measured using the modified Harris Hip Score, Non-Arthritic Hip Score, Hip Outcome Score Sport-Specific subscale, Hip Outcome Score Activities of Daily Living subscale, and iHOT-12. Pain and functional outcomes demonstrated significant improvement in nearly all the studies where they were reported. CONCLUSIONS Patients who underwent endoscopic management of GTPS commonly underwent repair of gluteal tendon tears, and in many cases had concomitant labral tears and chondral lesions identified intraoperatively. There were low rates of adverse events, repair failure, and revision surgery. Patient-reported functional outcomes were improved at follow-up at least 1 year postoperatively. LEVEL OF EVIDENCE IV, systematic review of level IV or better investigations.

Abstract
Tears in the gluteus medius and minimus tendons are a common cause of greater trochanter pain syndrome (GTPS). Given the non-specific clinical signs and imaging findings, they are often misdiagnosed, with delayed treatment. The lesions can show several aspects: trochanteric bursitis, simple tendinopathy, partial or full-thickness tear, tendon retraction, or fatty degeneration. Non-surgical treatment associates physical rehabilitation and activity modification, oral analgesics, anti-inflammatories and peri-trochanteric injections (corticosteroids, PRP). In the event of symptoms recalcitrant to medical treatment, surgery may be indicated. A 5-stage classification according to intraoperative observations and elements provided by MRI is used to guide technique: isolated bursectomy with microperforation, single or double row tendon repair, or palliative surgery such as muscle transfer (gluteus maximus with or without fascia lata). The development of conservative hip surgery now makes it possible to perform all of these surgical techniques endoscopically, with significant improvement in functional scores and pain in the short and medium term and a lower rate of complications than with an open technique. However, tendon retraction and fatty degeneration have been reported to be factors of poor prognosis for functional results and tendon healing and palliative tendon transfer gives mixed results for recovery of tendon strength. It is therefore preferable not to wait for the onset of Trendelenburg gait to propose endoscopic repair of the gluteus medius tendon in case of pain with a tear visible on MRI and failure of more than 6 months' medical treatment. Based on expert opinion, this article provides an update on the diagnosis of gluteus medius lesions, treatment, and in particular the place of endoscopy, indications and current results.

Recommendations in the rehabilitation of patients undergoing hip abductor tendon repair: a systematic literature search and evidence based rehabilitation protocol. Arch Orthop Trauma Surg 2022; 142:3165-3182. [PMID: 33983527 DOI: 10.1007/s00402-021-03952-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2020] [Accepted: 05/04/2021] [Indexed: 11/29/2022]
Abstract
INTRODUCTION Advanced hip imaging and surgical findings have demonstrated that a common cause of greater trochanteric pain syndrome (GTPS) is hip abductor tendon (HAT) tears. Traditionally, these patients have been managed non-operatively, often with temporary pain relief. More recently, there has been an increase in published work presenting the results of surgical intervention. A variety of open and endoscopic transtendinous, transosseous and/or bone anchored suture surgical techniques have been reported, with and without the use of tendon augmentation for repair reinforcement. While patient outcomes have demonstrated improvements in pain, symptoms and function, post-operative rehabilitation guidelines are often vague and underreported, providing no guidance to therapists. MATERIALS AND METHODS A systematic search of the literature was initially undertaken to identify published clinical studies on patients undergoing HAT repair, over a 3-year period up until May 2020. Following the application of strict inclusion and exclusion criteria, studies were identified and the detail relevant to rehabilitation was synthesized and presented. Published detail was combined with the authors clinical experience, with a detailed overview of rehabilitation proposed for this patient cohort. RESULTS A total of 17 studies were included, reporting varied detail on components of rehabilitation including post-operative weight bearing (WB) restrictions, the initiation of passive/active hip range of motion (ROM) and resistance exercises. A detailed rehabilitation guide is proposed. CONCLUSION In combining the current published literature on rehabilitation after HAT repair and our own clinical experience in the surgical management and post-operative rehabilitation of these patients, we present an evidence-based, structured rehabilitation protocol to better assist surgeons and therapists in treating these patients. This rehabilitation protocol has been implemented for several years through our institutions with encouraging published clinical outcomes.

Abstract
BACKGROUND Gluteal tendon tears (GTT) can cause pain and weakness of the hip. We analyze the impact of gluteal muscle fatty degeneration, atrophy and tear morphology on clinical outcomes of surgical repair. METHODS All sequential patients receiving surgical repair of GTTs via anchor sutures between 1/2015 and 11/2018 were retrospectively identified. MRIs were reviewed by a radiologist for tendon retraction, muscle atrophy and tear size. The Goutallier-Fuchs Classification (GFC) was used to quantify fatty degeneration as < 2° or ≥ 2°. Demographic and clinical variables were abstracted from the electronic records. The surveys HHS Section 1 and HOOS Jr. were obtained at last follow-up. The Pearson correlation and one-way ANOVA tests served for statistical analysis of clinical variance. RESULTS 38 patients were identified, 29 (76.3%) were female. The average age was 67. Of the 11 (28.9%) patients with a prior hip arthroplasty 87.5% of primary THAs had a direct lateral approach. 29 (76.3%) patients were treated open and 9 (23.7%) arthroscopically. At an average follow-up of 20.9 months, patients reported a significant improvement in pain (97%), analgesic use (85.7%), limp (52.6%) and abduction strength (54.2%) (all: P ≤ 0.01). GFC ≥ 2° were associated with significantly worse outcomes in terms of limp (0.19/3 vs. 1.2/3, P = 0.05), HHS-S1 (58.19 vs. 71.68, P = 0.04) and complication rates (37.5% vs. 0%, P = 0.02). There was a strong correlation between tear retraction (P = 0.005), tear size (P = 0.009) and muscle atrophy (P = 0.001) with GFC ≥ 2° but not with clinical outcomes. GFC ≥ 2° was strongly related to lateral THA exposures (P < 0.001). Surgical approach had no impact on clinical outcomes. CONCLUSION While fatty degeneration can negatively impact functional outcomes, pain relief is reliably achieved. Tear morphology and muscle atrophy did not correlate with outcomes in this patient cohort. Patients should be counseled to expect a residual limp after surgery if they have GFC ≥ 2° on MRI.

Abstract
BACKGROUND There is a paucity of information in the literature on midterm outcomes of endoscopic gluteus medius and/or minimus repair with concomitant labral treatment using only modern surgical techniques. PURPOSE To define the minimal clinically important difference (MCID) and Patient Acceptable Symptom State (PASS) at a minimum of 5 years postoperatively for patients undergoing endoscopic hip abductor repair with routine capsular closure. STUDY DESIGN Case series; Level of evidence, 4. METHODS Consecutive patients who underwent primary endoscopic repair of gluteus medius and/or minimus tears between January 2012 and December 2015 by the senior author were eligible for inclusion. Patient-reported outcome scores were assessed preoperatively and at 5 years postoperatively: Hip Outcome Score-Activities of Daily Living (HOS-ADL), HOS-Sport Specific (HOS-SS), modified Harris Hip Score (mHHS), 12-item International Hip Outcome Tool (iHOT-12), and visual analog scale (VAS) for pain. The MCID was uniquely calculated using the distribution method, and the PASS was determined via the anchor-based method utilizing receiver operating characteristic curves and Youden index. RESULTS A total of 46 patients were included in the study. The majority were female (87.0%), with a mean ± standard deviation age of 59.1 ± 8.9 years and body mass index of 27.3 ± 6.9. Significant postoperative improvements (P < .001) in each of the 5 patient-reported outcomes were observed at 5 years postoperatively. The MCID threshold values were calculated as follows: HOS-ADL, 11.5; HOS-SS, 15.1; mHHS, 13.3; iHOT-12, 11.8; and VAS, 15.8. The PASS thresholds were calculated as follows: HOS-ADL, 75.7; HOS-SS, 79.7; mHHS, 81.2; and iHOT-12, 60.8. A majority of patients achieved a clinically significant outcome, with 96.2% of patients reaching a threshold score for the MCID or PASS for at least 1 patient-reported outcome. CONCLUSION Endoscopic hip abductor repair with concomitant arthroscopic labral treatment has a high rate of achievement of clinically significant outcomes and survivorship at a minimum 5-year follow-up. We defined the MCID for the HOS-ADL, HOS-SS, mHHS, iHOT-12, and VAS outcome scores to be 11.5, 15.1, 13.3, 11.8, and 15.8, respectively. The PASS threshold scores for the HOS-ADL, HOS-SS, mHHS and iHOT-12 scores of 75.7, 79.7, 81.2, and 60.8, respectively. Future researchers and clinicians can use the MCID and PASS values established in this study to better evaluate mid-term outcomes of patients undergoing hip abductor repair.

Abstract
BACKGROUND Increasing evidence supports surgical intervention for hip abductor tears; however, the influence of fatty infiltration (FI) on outcomes after repair remains uncertain and has been addressed only in small case series. PURPOSE To clarify the relationship between FI and surgical outcomes for hip abductor tears. STUDY DESIGN Meta-analysis; Level of evidence, 4. METHODS A systematic review and meta-analysis was conducted according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. FI severity was assessed by Goutallier-Fuchs (G-F) grade. The relationship between FI and improvement in Harris Hip Score (HHS)/modified Harris Hip Score (mHHS) and visual analog scale (VAS) score for pain was examined with mixed-effects metaregression. Outcomes with open and endoscopic techniques were also compared. RESULTS A total of 4 studies (206 repairs in 201 patients) were eligible. High-grade FI was associated with significantly less improvement in HHS/mHHS than both no FI (6.761 less; 95% CI, 3.983-11.570; P = .002) and low-grade FI (7.776 less; 95% CI, 2.460-11.062; P < .001) but did not significantly influence VAS score (P > .05). Controlling for FI severity, we found no significant difference in HHS/mHHS improvement between open versus endoscopic repair (P > .05 at each level), but open repair resulted in significantly greater improvement in VAS score for every G-F grade (all P < .005). CONCLUSION Surgical intervention for symptomatic hip abductor tendon tears improved outcomes as reflected by change in HHS/mHHS; however, the presence of high-grade FI resulted in less improvement. FI severity did not influence VAS scores for pain. Although no differences were found between open and endoscopic repairs in terms of FI-adjusted improvement in HHS/mHHS, open repairs resulted in significantly greater pain relief at each FI level.

Abstract
The gluteus medius originates on the posterior face of the ilium between the posterior and anterior gluteal lines and inserts into the lateral and superoposterior facets of the greater trochanter. Because of the asymmetric nature of the muscle, tears are more likely to occur on the thinner anterolateral portion of the tendon footprint. Gluteus medius tears range from interstitial, partial thickness tears to retracted, full-thickness tears and may result from trauma, but they are more commonly the result of chronic degeneration. Patients commonly present with lateral hip pain aggravated by weight bearing and sleeping on the affected side, weakness in abduction, and the Trendelenburg sign observable on physical examination. Indications for surgery include failed conservative treatment and an ultrasound or magnetic resonance imaging study demonstrating a torn tendon. Surgical intervention aims to reapproximate and secure the torn tendon to the tendon footprint on the greater trochanter via suture anchors. Both open and endoscopic techniques have shown to be effective methods for treating gluteus medius tears at short- and long-term follow-up; however, endoscopic techniques have been shown to result in fewer postoperative complications, such as retear. A recent systematic review and meta-analysis found patients with more severe fatty infiltration (FI) may experience greater improvement after open repair, whereas patients with less severe FI may benefit more from endoscopic treatment. A double-row repair maximizes contact area between tendon and bone and has shown to be superior to single-row repair with an endoscopic technique.

Abstract
PURPOSE 1) To assess the possible relationship between the morphology of femur or acetabulum and the gluteus medius pathology. 2) To analyze the outcome of isolated arthroscopic treatment of femoroacetabular impingement (FAI) for patients with radiographic gluteus medius tear. METHODS We performed a retrospective study of FAI patients who underwent arthroscopy between January 2016 to December 2019. Demographic data, such as sex, age, body mass index (BMI), symptom duration, were collected. Radiographic parameters, including alpha angle, lateral center-edge angle (LCEa), femur neck-shaft angle (NSa), gluteus medius pathology, were also collected. Exclusion criteria were previous hip conditions, such as osteoarthritis (Tönnis grade > 1), rheumatoid arthritis, ankylosing spondylitis, snapping hip, previous surgery on the ipsilateral hip, or incomplete data. We followed up these patients with radiographic gluteus medius tear. No surgical procedure for gluteus medius was performed. The minimum follow-up period was 13 months. Patient-reported outcomes, such as modified Harris Hip score (mHHS), visual analog scale (VAS), and patient acceptable symptom state (PASS), as well as physical examination data, including tenderness at the greater trochanter, abductor weakness, limping gait, and positive Trendelenburg sign or test, were gathered preoperatively and postoperatively. RESULTS A total of 569 hips (314, 55.2% male) were collected eventually, with a mean age of 36.5 ± 10.4 years (range: 13.0 to ∼65.0). Gluteus medius pathology was found in 209 (36.7%) hips, including 41 (7.2%) partial-thickness tears and 10 (1.8%) complete tears. The NSa of the normal, tendinosis, partial tear, and complete tear groups was 133.8 ± 4.7°, 130.6 ± 3.8°, 129.4 ± 3.9°, and 129.6 ± 3.4°, respectively (P < .001). The LCEa of each group was 31.7 ± 35.7°, 33.3 ± 6.5°, 34.9 ± 6.8°, and 33.7 ± 8.1°, respectively (P = .004). On multivariable logistic regression analysis, lower NSa and higher LCEa were identified as risk factors for developing gluteus medius pathology (P < .001). For patients with gluteus medius tear, two cases were lost to follow-up and two cases had incomplete data. The mean follow-up period of the remaining 47 hips was 29.5 ± 12.9 (range: 13 to 59) months. The mHHS improved from 54.8 ± 19.1 to 90.1 ± 6.7 points (P < .001), and VAS decreased from 6.8 ± 1.6 to 3.0 ± 1.6 points (P < .001). Forty-two cases met the threshold of PASS, with a rate of 89%. The abductor strength increased from 4.1 ± 1.00 to 4.6 ± .7 grades (P = .002). However, for patients with a completely torn gluteus medius, improvement of abductor strength was not significant statistically (3.4 ± .9 to 3.9 ± .9, P = .234). CONCLUSION There was a correlation between lower NSa/higher LCEa and gluteus medius pathology. Isolated arthroscopic treatment of FAI for patients with radiographic gluteus medius tear can gain satisfactory patient-reported outcomes. LEVEL OF EVIDENCE Therapeutic case series, IV.

Abstract
Purpose To compare the repair strength, gap formation, and mode of failure between endoscopic and open double-row gluteus medius repairs in a cadaveric model. Methods Six pairs of fresh-frozen human cadavers were used in this study. Gluteus medius tears were created in an open fashion and then repaired with either open or endoscopic techniques. Specimens were manually preloaded to 5 N, then cycled between 20-50 N for 150 cycles s. Then, a ramp to/s. Specimens were then returned to 10 N and ramped to failure at 1 mm/s. Gap formation and strengths of the construct were compared for the 2 techniques. Results Biomechanical testing resulted in no significant differences in ultimate load (P = .86) or gap formation (P > .10) between groups. Ninety-two percent of specimens failed near the muscle origin on the ilium. Conclusions This study shows that both open and endoscopic gluteus medius repairs are stronger than the muscle–bone interface in a cadaveric model and loaded biomechanically in tension between the ilium origin and femoral insertion. Further, endoscopic technique is able to replicate open, knotless gluteus medius repair technique in terms of gap formation in physiologic (i.e., subfailure) cyclic loading. Clinical Relevance Gluteus medius tendinopathy is an increasingly common recognized etiology of lateral hip pain. When tears occur, debate exists over whether open or endoscopic repair procedures are optimal. Double-row endoscopic gluteus medius repair with knotless suture anchors may be an alternative to open repair.

Abstract
Purpose To report on clinical presentations and outcomes in patients who underwent an isolated endoscopic gluteus medius (GM) repair. Methods We retrospectively reviewed and prospectively collected data on patients who underwent a primary isolated endoscopic GM repair. Patients were included if the following patient-reported outcome scores were obtained preoperatively and at minimum 2-year follow-up: modified Harris Hip Score (mHHS), Non-arthritic Hip Score (NAHS), and visual analog scale (VAS) score. The minimal clinically important difference (MCID) for the mHHS, NAHS, and Hip Outcome Score–Sports Specific Scale was uniquely calculated for this study. Patients who underwent concomitant procedures including hip arthroplasty and hip arthroscopy were excluded. Results A total of 26 hips met all inclusion and exclusion criteria, of which 23 hips (88.5%) (22 patients) had a minimum 2-year follow-up. Nineteen hips had a partial-thickness GM tear; 17 (89.5%) were high-grade partial-thickness tears treated with a side-to-side repair through a transtendinous window. Four full-thickness tears with no retraction or fatty infiltration were able to be repaired endoscopically. The mHHS, NAHS, and VAS score all significantly improved (P < .05) from baseline: The mHHS improved from 55.9 to 75.4 (P = .005); the NAHS, from 58.8 to 79.2 (P = .003); and the VAS score, from 5.9 to 3.6 (P = .009). The MCID was calculated for the mHHS, NAHS, and Hip Outcome Score–Sports Specific Scale as 5.8, 7.1, and 11.0, respectively. Most patients achieved the MCID for all 3 patient-reported outcome scores. Conclusions Appropriately selected patients without concomitant intra-articular hip pathology may achieve successful outcomes at a minimum 2-year follow-up after an isolated endoscopic GM repair. Most isolated endoscopic GM repairs were performed for partial-thickness GM tears. Level of Evidence Level IV, case-series study.

Arthrosc Sports Med Rehabil 2021; 3:e1321-e1327. [PMID: 34712970 PMCID: PMC8527271 DOI: 10.1016/j.asmr.2021.05.013] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Accepted: 05/19/2021] [Indexed: 11/07/2022] Open
Abstract
Purpose To evaluate the 1-year outcomes of a small patient series following open gluteus medius/minimus repair with human dermal allograft incorporated into the repair construct using a double-row repair. Methods Data from consecutive patients undergoing a superior gluteal reconstruction for massive, irreparable abductor tendon tears with severe tendon loss and atrophy by a single fellowship trained surgeon from January 2018 to May 2019 were collected and analyzed. Baseline demographic data and magnetic resonance imaging were collected preoperatively. Clinical outcomes including Hip Outcome Score–Activities of Daily Living (HOS-ADL), HOS–Sports Subscale (HOS-SS), modified Harris hip score (mHHS), international Hip Outcome Score-12 (iHOT-12), visual analog scale (VAS) pain, and VAS satisfaction were recorded at 1-year postoperatively. Results A total of 8 patients underwent open superior gluteal reconstruction for severe hip abductor deficiency. The mean age and body mass index were 62.6 ± 7.3 years and 29.6 ± 5.3 kg/m2, respectively. The majority of patients were female (N = 7, 87.5%). Three (37.5%) patients had undergone previous endoscopic gluteus medius repair and presented for revision surgery. All patients had full-thickness tears with gluteus medius and gluteus minimus involvement. Patients were evaluated at an average of 11.5 ± 1.7 months from the initial surgical intervention and reported a mean HOS-ADL of 82.9 ± 24.3, HOS-SS of 73.2 ± 37.3, mHHS of 83.6 ± 17.1, iHOT-12 of 63.9 ± 27.4, VAS Pain of 30.0 ± 23.1, and VAS Satisfaction of 87.1 ± 17.0. There was no evidence of retears in this patient cohort as defined by physical examination findings and/or corroborating magnetic resonance imaging. Conclusions Superior gluteal reconstruction for massive, irreparable abductor tendon tears with severe tendon loss and atrophy is a technique that demonstrates promising 1-year postoperative outcomes in both primary and revision patients. Level of Evidence Level IV, therapeutic case series.

Conversion to Total Hip Arthroplasty After Hip Arthroscopy: A Cohort-Based Survivorship Study With a Minimum of 2-Year Follow-up. J Am Acad Orthop Surg 2021; 29:885-893. [PMID: 33201044 DOI: 10.5435/jaaos-d-20-00748] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2020] [Accepted: 09/20/2020] [Indexed: 02/01/2023] Open
Abstract
INTRODUCTION The purpose of this study was to determine which patient, provider, and surgical factors influence progression to total hip arthroplasty (THA) after hip arthroscopy (HA) through a large cohort-based registry. METHODS All patients ≥18 years who underwent unilateral HA in Ontario, Canada, between October 1, 2010, and December 31, 2016, were identified with a minimum of 2-year follow-up. The rate of THA after HA was reported using Kaplan-Meier survivorship analyses. A Cox proportional hazard model was used to assess which factors independently influenced survivorship. RESULTS A total of 2,545 patients (53.2% female, mean age 37.4 ± 11.8 years) were identified. A total of 237 patients (9.3%) were identified to have undergone THA at a median time of 2 years after HA, with an additional 6.3% requiring a revision arthroplasty at a median time of 1.1 years. Patients who underwent isolated labral resection (hazard ratio [HR]: 2.55, 95% confidence interval [CI]: 1.51 to 4.60) or in combination with osteochondroplasty (OCP) [HR: 2.11, 95% CI: 1.22 to 3.88] were more likely to undergo THA versus patients who underwent isolated labral repair or in combination with an OCP, respectively. Older age increased the risk for THA (HR: 14.0, 95% CI: 5.76 to 39.1), and treatment by the highest-volume HA surgeons was found to be protective (HR: 0.55, 95% CI: 0.33 to 0.89). DISCUSSION Using our methods, the rate of THA after HA was 9.3% at 2 years. The rate of revision arthroplasty was 6.3% at 1 year. Patients who underwent labral resection, isolated OCP, and/or were of increased age were at increased independent risk of conversion to THA. Those treated by the highest-volume HA surgeons were found to be at reduced risk of conversion to THA.

Abstract
Gluteal tendon tears represent a common but underreported cause of lateral hip pain and dysfunction. In case of conservative management failure, a surgical procedure must be performed to relieve patient symptoms. Current operative treatments, either open or endoscopic, have been however associated with different drawbacks which led to the introduction of the mini-open technique. The aim of this study was to evaluate and report the short-term outcomes of patients operated through the aforementioned surgical technique for gluteus medius (GM) chronic tears. We retrospectively analysed the records of 14 consecutive patients operated at the La Tour hospital by mini-open repair using a double-row technique for full-thickness GM chronic tears. Intra- and post-operative complications were recorded. The pre- and post-operative pain on visual analogue scale (pVAS), modified Harris Hip score (mHHS), abduction strength and gait dysfunction were assessed for all patients. Pre- and post-operative values were compared to evaluate whether improvements were statistically significant and clinically relevant. The study cohort comprised 13 women (93%) and 1 man (3%) aged 62.4 ± 18.0 at index surgery. No intra- or post-operative complications were noted. Compared to pre-operative values, patients reported a significant improvement in mHHS (59.1 ± 7.1 vs 92.7 ± 4.6) and pVAS (7.4 ± 1.0 vs 1.3 ± 1.3) at last follow-up. Patients exhibited a perfect improvement in muscle strength (3.6 ± 0.5 vs 5.0 ± 0.0), and the proportion of patients with a positive Trendelenburg sign decreased from 71% to 0%. Mini-open repair of chronic GM tendon tears using a double-row technique demonstrated excellent clinical and functional outcomes at short follow-up. Level of Evidence: IV.

Clinical outcomes of latissimus dorsi tendon transfer and superior capsular reconstruction for irreparable rotator cuff tears: a systematic review. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2021; 32:1023-1043. [PMID: 34370112 DOI: 10.1007/s00590-021-03046-5] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/28/2021] [Accepted: 04/25/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND Functionally irreparable rotator cuff tears (FIRCTs) present an ongoing challenge to the orthopedic surgeon. The aim of this systematic review was to critically compare the outcomes of three latissimus dorsi tendon transfer (LDT) techniques and two superior capsular reconstruction (SCR) techniques in treatment of FIRCTs. METHODS A systematic review of studies evaluating the outcome of FIRCT treatment was performed via a search of four databases in April 2020. Each included study was reviewed in duplicate by two reviewers for evaluation of methodological quality. The treatments analyzed were arthroscopic LDT (aLDT), open LDT Gerber technique (oLDTG), open LDT L'Episcopo technique (oLDTL), SCR with allograft (SCR-Allo), and SCR with autograft (SCR-TFL). Demographics, range of motion, patient-reported outcome measures, radiographic acromiohumeral distance (AHD), treatment failures, and revisions were recorded. RESULTS Forty-six studies (1287 shoulders) met criteria for inclusion. Twenty-three studies involved open latissimus transfer, with 445 shoulders undergoing oLDTG with mean follow-up of 63.2 months and 60 patients undergoing oLDTL with mean follow-up of 51.8 months. Ten studies (n = 369, F/U 29.2mo) reported on aLDT. Seven studies (n = 253, F/U 16.9mo) concerned SCR-Allo, and six studies (n = 160, F/U 32.mo) reported on SCR-TFL. Range of motion and subjective outcome scores improved in all techniques with no differences across treatments. Both SCR methods provided greater improvement in AHD than open LDT methods (p < 0.01). The re-tear rates were lower in both oLDT groups compared to the SCR groups (p = 0.03). Clinical failure rates were higher in the SCR-Allo and oLDTG groups, while overall treatment failures were lowest in oLDTL compared to all four other groups. CONCLUSION SCR techniques were associated with improved short-term radiographic acromiohumeral distance, while the open LDT techniques had lower tendon re-tear and treatment failure rates. All techniques resulted in improved clinical outcomes and pain relief compared to preoperative levels with no differences across techniques. LEVEL OF EVIDENCE IV Systematic review of case series and cohort studies.

Arthroscopic management of greater trochanter pain syndrome and abductor tears has demonstrated promising results in terms of improvement in pain scores and functional outcomes: a scoping review. Knee Surg Sports Traumatol Arthrosc 2021; 29:2401-2407. [PMID: 33044606 DOI: 10.1007/s00167-020-06322-9] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2020] [Accepted: 10/02/2020] [Indexed: 11/26/2022]
Abstract
PURPOSE Greater trochanteric pain syndrome (GTPS) refers to the constellation of signs and symptoms related to pain in the trochanteric region and has recently replaced the previously ubiquitous term of 'greater trochanteric bursitis'. GTPS is common, particularly in women 50-79 years of age, and the understanding and management of GTPS have expanded considerably in recent years to include management with arthroscopic and endoscopic techniques in recalcitrant cases. The purpose of this scoping literature review was to summarize the current evidence on arthroscopic management of GTPS including sources of evidence, key concepts, and gaps in the literature. METHODS A thorough electronic database search included studies published from 2009 to June 14, 2020. A total of 52 peer-reviewed articles were identified within the literature on arthroscopic or endoscopic management of GTPS. RESULTS Of the 52 identified papers, 12 were technique descriptions, 10 papers were review articles, and 30 papers were original clinical papers. Of the 30 clinical papers, 24 (80%) were of level IV evidence, 5 (17%) were of level III evidence, and 1 (3%) was level II evidence. Among the 30 clinical studies, 988 patients were included with 761 (77%) female. Indications for surgical management included a failed trial of conservative management in all 30 studies, typically after a period of 3-6 months. Surgical management consisted of arthroscopic/endoscopic abductor tendon repair in 16 (53%) studies, arthroscopic/endoscopic bursectomy and iliotibial band release in 12 (40%) studies, and arthroscopic/endoscopic gluteal tendon contracture release in 2 (7%) studies. CONCLUSION Overall, results following arthroscopic management of GTPS and abductor tears have been promising, including significantly improved pain scores and functional outcomes at final post-operative assessment. These studies support continued use and investigation of arthroscopic management strategies of GTPS and pave the way to conduct larger prospective studies to confirm these results in the future.

Abstract
PURPOSE The purpose of this study was to evaluate and compare the functional outcomes after endoscopic repair of partial or full-thickness gluteus medius tears at a minimum 2 years' follow-up. METHODS Patients with isolated tears of the gluteus medius tendon repaired endoscopically between 2012 and 2017 were evaluated at a minimum 2 years of follow-up. Patients with large, retracted and/or irreducible tears, advanced atrophy, or fatty degeneration or with concomitant other hip pathology were excluded. Functional outcomes were assessed using the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), and visual analog scale (VAS) for pain preoperatively and at the last follow-up RESULTS: Forty-six patients, 3 men and 43 women with a mean (SD) age of 63 (9; range, 43-82) years, were included. Thirty-three patients (72%) had partial-thickness tears and 13 (28%) had full-thickness tears. Pain was reduced significantly from a median of 8 (IQR: 6-8) at the preoperative visit to a median of 2 (IQR: 15) at the most recent follow-up (P < .0001). The mHHS and NAHS improved significantly from a median of 44 (IQR: 35-52) to 80 (IQR: 64-87) (P < .0001) and 52 (IQR: 43-56) to 75 (IQR: 66-94) (P < .0001), respectively. These improvements were clinically relevant and surpass the reported minimal clinically important difference. Patients with partial tears had significant functional gains in the mHHS in comparison with patients with full-thickness tears (P = .02). No other statistically significant difference between groups of tear grade was observed. CONCLUSIONS Endoscopic repair of gluteus medius tendon tears yields excellent functional outcomes at a minimum follow-up of 2 years. A lower functional improvement for full-thickness tears was observed; this difference was statistically significant for 1 of the 2 scores evaluated. LEVEL OF EVIDENCE Level III, retrospective comparative cohort.

Abstract
The hip trochanteric bursa, tendinous insertions of the gluteal muscles, and the origin vastus lateralis make up the main structures of the peritrochanteric space. Greater trochanteric pain syndrome (GTPS) refers to pain generated by one or multiple disorders of the peritrochanteric space, such as trochanteric bursitis, gluteus medius and minimus tendinopathy or tear, and disorders of the proximal iliotibial band. Patients with GTPS might present with associated intra-articular hip pathology, which requires further investigation and appropriate management. Successful midterm outcomes have been reported in patients undergoing surgical treatment of GTPS using an open or endoscopic approach.

Abstract
BACKGROUND Patients presenting with lateral hip pain may pose a difficult diagnostic challenge, as pain can be due to various causes. PURPOSE/HYPOTHESIS The purpose was to identify risk factors and predictors for symptomatic hip abductor tears in a cohort of patients undergoing primary hip arthroscopy for femoroacetabular impingement syndrome. We hypothesized that body mass index (BMI), female sex, age, and presence of chondral damage would be significant predictors of hip abductor pathologies. STUDY DESIGN Cohort study (diagnosis); Level of evidence, 3. METHODS Data were prospectively collected and retrospectively reviewed. Patients were included if they underwent primary hip arthroscopy between March 2009 and December 2019. Patients with Tönnis grade >1, previous hip conditions, incomplete radiographic data, or open procedures were excluded. All demographic variables, intraoperative measurements, and radiographic measurements were assessed using a bivariate analysis. A stepwise logistic regression was used to determine predictive variables. RESULTS In total, 255 hips with a hip abductor tear that underwent hip arthroscopy and 2106 hips without a tear that underwent hip arthroscopy were included. The stepwise logistic regression successfully created a predictive model using age, sex, BMI, lateral joint space, and alpha angle as variables. The efficiency of the predictive model was 90.7%, with an area under the curve of 0.894. The odds of having a hip abductor tear were 7.41 times higher in females (odds ratio [OR], 7.41; 95% CI, 4.61-11.9). Each additional year of age was associated with a 13.7% (OR, 1.137; 95% CI, 1.12-1.16) increase in the odds of having a tear. Similarly, with each 1-unit increase in BMI, the odds of having a tear increased by 3.4% (OR, 1.034; 95% CI, 1.01-1.06). CONCLUSION This study successfully created a predictive model that identified female sex (OR, 7.41), increasing age (OR, 1.137 for each year), and increased BMI (OR, 1.034 for each unit of BMI) as significant independent predictors of the presence of hip abductor tears in patients undergoing hip arthroscopy for femoroacetabular impingement syndrome. This model can be used in support of physical examination and imaging suggestive of hip abductor pathology to preoperatively identify the probability of a symptomatic hip abductor tear in these patients.

Orthop J Sports Med 2021; 9:2325967120967968. [PMID: 33553438 PMCID: PMC7844460 DOI: 10.1177/2325967120967968] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2020] [Accepted: 06/30/2020] [Indexed: 01/06/2023] Open
Abstract
Background: Gluteus medius (GM) tears are a known cause of dysfunction and disability predominantly in older women. Purpose To report on return to activity, patient-reported outcomes (PROs), and a uniquely calculated minimal clinically important difference (MCID) at a minimum 2-year follow-up for active patients who had undergone either an endoscopic or an open GM repair. Study Design: Case series; Level of evidence, 4. Methods: Patients were considered eligible if they (1) underwent a GM repair with or without concomitant central and peripheral compartment procedures; (2) had baseline preoperative and minimum 2-year scores for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), Hip Outcome Score–Sports Specific Subscale (HOS-SSS), and visual analog scale (VAS) for pain; and (3) participated in a physical activity or sport within 1 year before their surgery. Return to activity was defined as the patient being able to participate in his or her activity at a minimum of 2 years postoperatively. Results: Of 87 eligible patients, 84 (96.6%) met all inclusion criteria. The mean follow-up was at 44.5 months. Six patients (7.1%) underwent an open GM repair, while the remaining 78 (92.9%) underwent an endoscopic GM repair. Concomitant central and peripheral compartment arthroscopic procedures were performed in 69 patients (82.1%). All PROs significantly (P < .001) improved as follows: mHHS, from 59.0 to 85.8; NAHS, from 57.9 to 84.0; HOS-SSS, from 32.6 to 63.7; and VAS pain, from 5.4 to 1.9. A total of 57 patients (67.9%) returned to their preoperative activity at the 2-year follow-up. The MCID was calculated for the mHHS, NAHS, and HOS-SSS to be 7.5, 7.4, and 10.9, respectively, with 79.3%, 86.4%, and 70.2% of patients achieving the MCID for each respective PROs. Conclusion: Active patients over the age of 50 years may benefit from endoscopic or open repair of GM tears, as the majority of patients in our cohort were able to return to their activity of choice. All measured PROs had significantly improved at a minimum 2-year follow-up, with high survivorship, satisfaction, and clinical effectiveness. Patients with partial-thickness tears compared with full-thickness tears and those who underwent isolated GM repair compared with GM repair with concomitant procedures had similar return to activity rates and PROs at the latest follow-up.

Abstract
BACKGROUND Although hip arthroscopy has been shown to have favorable results, there is a paucity of literature describing predictive factors of 5-year clinical outcomes. PURPOSE To identify predictive factors of midterm outcomes after hip arthroscopy in a cohort of 1038 patients whose outcomes at minimum 2-year follow-up were previously reported. In addition, to provide a comparison of short- and midterm predictive factors in outcome measures after hip arthroscopy. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS Data were prospectively collected and retrospectively reviewed on all patients undergoing hip arthroscopy between February 2008 and June 2012. Patients were included if they had minimum 5-year follow-up on 2 patient-reported outcomes: Nonarthritic Hip Score (NAHS) and modified Harris Hip Score. Patients were excluded if they had any previous ipsilateral hip conditions. Using bivariate and multivariate analyses, we analyzed the effect of 36 pre- and intraoperative variables on the NAHS, modified Harris Hip Score, and conversion to total hip arthroplasty. RESULTS A total of 1038 patients met the inclusion criteria for the 2-year study, and 860 met our listed inclusion criteria for the 5-year study. The mean follow-up time was 62.0 months (range, 60.0-120.0 months). The bivariate analysis identified 10 variables (4 categorical and 6 continuous) that were predictive of 5-year postoperative NAHS. For the multivariate analysis, 7 variables were identified as being significant: preoperative NAHS, body mass index (BMI), age, lateral joint space, alpha angle, revision hip arthroscopy, and acetabular microfracture. These 7 variables were also predictive in the bivariate analysis. Age, BMI, revision hip arthroscopy, Tönnis grade, sex, trochanteric bursectomy, femoral head cartilage damage, and acetabular inclination were significant predictors of conversion to total hip arthroplasty. CONCLUSION This study reports favorable midterm clinical outcomes in the largest cohort of hip arthroscopies with minimum 5-year follow-up in the literature to date. Seven variables were identified as being significant predictors of postoperative NAHS in the bivariate and multivariate analyses: preoperative NAHS, BMI, age, lateral joint space, alpha angle, revision hip arthroscopy, and acetabular microfracture. Of these, preoperative NAHS, BMI, age, and revision hip arthroscopy were predictive of 2- and 5-year postoperative NAHS. These predictive factors may prove useful to clinicians in determining indications for hip arthroscopy and counseling patients on its expected outcomes.

Abstract
BACKGROUND Gluteus medius (GM) tears often occur in women aged >50 years. There is a paucity of literature comparing sex-based differences in those undergoing GM repair. PURPOSE To report differences between women and men in clinical presentations and patient-reported outcome (PRO) scores at a minimum 2-year follow-up after undergoing GM repair. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were prospectively collected and retrospectively reviewed. All included patients had postoperative scores for the following PROs: modified Harris Hip Score (mHHS), Non-arthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale (HOS-SSS), and International Hip Outcome Tool-12. Men were propensity score matched 1:3 to women according to concomitant arthroscopic procedures and follow-up time. Clinical effectiveness was determined through a uniquely calculated minimal clinically important difference (MCID) for the mHHS and NAHS specific to this study population. RESULTS Thirteen men were successfully propensity score matched to 39 women. Women and men were 55.87 ± 11.0 and 62.38 ± 11.63 years old (mean ± SD), respectively (P = .02). Men were at increased risk for associated lumbar pathology as compared with women (relative risk, 3.32; P = .02). Women showed significant improvement from preoperative to minimum 2-year follow-up for the mHHS (59.32 ± 15.36 to 83.81 ± 16.82; P < .01), NAHS (56.23 ± 15.61 to 83.78 ± 17.66; P < .01), HOS-SSS (33.35 ± 20.28 to 67.88 ± 32.35; P < .01), and visual analog scale (5.48 ± 2.00 to 1.93 ± 2.29; P < .01). Similarly, men showed significant improvement for the mHHS (63.50 ± 16.41 to 84.77 ± 13.91; P < .01), NAHS (61.52 ± 9.87 to 84.42 ± 14.87; P < .01), HOS-SSS (33.97 ± 21.20 to 63.62 ± 26.20; P < .01), and visual analog scale (4.93 ± 2.69 to 1.86 ± 2.10; P < .01). The MCIDs for the mHHS and NAHS were calculated to be 7.89 and 7.24. Of the women, 28 (72%) and 34 (87%) met the MCID for the mHHS and NAHS. Eleven (85%) men met the MCID for the mHHS and NAHS. CONCLUSION These results suggest that women and men can both benefit after GM repair. Men were older and had increased risk for associated lumbar pathology than women at the time of surgery. Men and women both experienced significant improvements in PROs and compared favorably in terms of clinical effectiveness at a minimum 2-year follow-up.

Abstract
PURPOSE To report mid-term outcomes of patients who underwent endoscopic gluteus medius (GM) repair with arthroscopic labral treatment and to compare them with a control cohort of patients who underwent arthroscopic labral treatment without an endoscopic GM repair. METHODS Data were prospectively collected and retrospectively reviewed for all patients who underwent primary hip arthroscopy between February 2008 and August 2013. Patients were included if they underwent arthroscopic labral treatment, endoscopic GM repair, and had preoperative with minimum 5-year follow-up for the following patient-reported outcomes: modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), and Hip Outcome Score-Sports Specific Subscale (HOS-SSS). Propensity score matching was used to create a control cohort of patients who underwent primary arthroscopic labral treatment without GM repair. RESULTS There were a total of 46 patients with GM repair eligible for the current study, of whom 43 (93.5%) had 5-year follow-up. The average follow-up time was 73.4 months. At minimum 5-year follow-up, all PROs significantly improved (P < .001). Among the entire GM repair cohort, rates for achieving the patient acceptable symptomatic state (PASS) for mHHS, HOS-SSS, and international Hip Outcome Tool (iHOT-12) were 74.4%, 51.9%, and 71.8%, respectively. Rates for reaching a minimal clinically important difference for mHHS, NAHS, and HOS-SSS were 79.5%, 89.7%, and 73.1%, respectively. When the GM repair cohort was matched, there were 37 cases in the GM repair cohort and 78 in the control cohort. The GM repair cohort outcomes compared satisfactorily to the control cohort for mHHS (82.3 vs 82.6), NAHS (81.9 vs 82.3), and HOS-SSS (66.3 vs 67.5). Rates of achieving minimal clinically important difference and PASS for mHHS, NAHS, HOS-SSS, and iHOT-12 were also favorable. CONCLUSIONS Endoscopic GM repair with arthroscopic labral treatment results in safe, durable, and significant improvement in PROs at a minimum 5-year follow-up. The outcomes compared favorably with a control cohort without GM tears. LEVEL OF EVIDENCE III, retrospective comparative study.

Abstract
IMPORTANCE Operative treatment of gluteal tendon tears is becomingly increasingly more common with varying surgical techniques and rehabilitation protocols. OBJECTIVE To perform a systematic review of gluteal tendon repair as it relates to tear characteristics, rehabilitation protocols, patient-reported outcomes, satisfaction, resolution of gait deviation and complication rates. EVIDENCE REVIEW A comprehensive literature search of PubMed and Embase/MEDLINE was used to identify all literature pertaining to gluteal tendon repair. A total of 389 articles were identified. FINDINGS A total of 22 studies (611 hips) were included in this review. The majority of tears were noted to be partial thickness (77.9% vs 22.1%). Both arthroscopic and open repair demonstrated improvements in functional outcomes. Within studies documenting gait deviation, 54% were noted to have gait deviation preoperatively, of which approximately 70% had resolution following repair. On average, abduction strength increased almost one whole grade (0.84) following repair. Overall complication rate was found to be 5.2% (20 of 388 hips). Endoscopic repair demonstrated a decreased complication rate compared with open (0.7% vs 7.8%). Retear rate was found to be 3.8%, with open repair having a slightly increased rate compared with endoscopic repair (3.4% vs 4.1%). CONCLUSIONS AND RELEVANCE The majority of tears tend to be partial thickness with involvement of gluteus medius in almost all cases and concomitant involvement of gluteus minimus in close to half of cases. Both endoscopic and open gluteal tendon repairs resulted in improvements in outcomes and functional improvement. Retear rates were similar between the two repair techniques, while endoscopic repair demonstrated a lower complication rate. LEVEL OF EVIDENCE Level IV, systematic review.

Abstract
Abductor tendon lesions and insertional tendinopathy are the most common causes of lateral thigh pain. Gluteal tendon pathology is more prevalent in women and frequency increases with age. Chronic atraumatic tears result in altered lower limb biomechanics. The chief complaint is lateral thigh pain. Clinical examination should include evaluation of muscle strength, lumbar spine, hip and fascia lata pathology. The hip lag sign and 30-second single leg stance tests are useful in diagnosing abductor insufficiency. Magnetic resonance imaging (MRI) is the gold-standard investigation to identify abductor tendon tears and evaluate the extent of muscle fatty infiltration that has predictive value on the outcome of abductor repair. Abductor tendinosis treatment is mainly conservative, including non-steroidal anti-inflammatory medications, activity modification, local corticosteroid injections, plasma-rich protein, physical and radial shockwave therapy. The limited number of available high-quality studies on treatment outcomes and limited evidence between tendinosis and partial ruptures make it difficult to provide definite conclusions regarding the best management of gluteal tendinopathy. Surgical management is indicated in complete and partial gluteal tendon tears that are unresponsive to conservative treatment. There are various open and arthroscopic surgical procedures for direct repair of abductor tendon tears. There is limited evidence concerning surgical management outcomes. Prerequisites for effective tendon suturing are neurologic integrity and limited muscle fatty infiltration. Chronic irreparable tears with limited muscle atrophy and limited fatty infiltration can be augmented with grafts. Gluteus maximus or/vastus lateralis muscle transfers are salvage reconstruction procedures for the management of chronic end-stage abductor tears with significant tendon insufficiency or gluteal atrophy.

Abstract
Background: Gluteus medius (GM) tears are a well-established source of pain and disability. An open approach has been recognized with complete full-thickness and large GM tears, yet the current literature provides few reports on outcomes for this specific situation. Purpose: To report and analyze minimum 2-year patient-reported outcomes (PROs) from patients who underwent open GM repair in the setting of a full-thickness tear with or without concomitant hip arthroscopy through use of contemporary tendon repair techniques. Study Design: Case series; Level of evidence, 4. Methods: Prospectively collected data were retrospectively reviewed for patients who underwent hip preservation surgery and total hip arthroplasty (THA) between April 2008 and May 2017. Patients were included in this study if they underwent open repair of GM full-thickness tears. The exclusion criteria were incomplete follow-up, workers’ compensation status, repair regarding size and pattern of the GM, open repair of partial GM tear, open repair with allograft or autograft augmentation, and/or additional gluteus maximus transfer. Pre- and postoperative PROs for the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score Sport-Specific Subscale (HOS-SSS), and visual analog scale (VAS) score for pain and satisfaction were recorded. Statistical significance was set at P < .05. Results: A total of 36 patients were included, of whom 12 received concomitant hip arthroscopy for intra-articular procedures. The mean ± SD age, body mass index, and follow-up time were 65.18 ± 12.69 years, 28.97 ± 4.95 kg/m2, and 40.8 ± 26.19 months, respectively. At minimum 2-year follow-up, the following outcome measures improved significantly: mHHS (from 54.72 ± 15.89 to 73.12 ± 19.47; P < .0001), NAHS (from 56.05 ± 12.47 to 75.22 ± 19.15; P < .0001); HOS-SSS (from 20.30 ± 20.21 to 44.23 ± 35.85; P < .0001), and VAS (from 4.95 ± 2.70 to 2.67 ± 2.81; P < .0001). There was 1 (2.8%) conversion to THA at 48 months after the index procedure. Conclusion: Patients who underwent open repairs in the setting of full-thickness GM tears via contemporary tendon repair techniques, with or without concomitant hip arthroscopy, achieved favorable results in several PRO scores at minimum 2-year follow-up.

Abstract
BACKGROUND Little is known about the relative efficacy of open (OGR) vs endoscopic (EGR) gluteal tendon repair of gluteal tendon tears in minimizing pain and restoring function. Our aim is to compare these 2 surgical techniques and quantify their impact on clinical outcomes. METHODS All patients undergoing gluteal tendon tear repair at our institution between 2015 and 2018 were retrospectively reviewed. Pain scores, limp, hip abduction strength, and the use of analgesics were recorded preoperatively and at last follow-up. The Hip disability and Osteoarthritis Outcome Score Junior and Harris Hip Score Section1 were obtained at last follow-up. Fatty degeneration was quantified using the Goutallier-Fuchs Classification (GFC). Statistical analysis was conducted using one-way analysis of variance and t-tests. RESULTS Forty-five patients (mean age 66, 87% females) met inclusion criteria. Average follow-up was 20.3 months. None of the 10 patients (22%) undergoing EGR had prior surgery. Of 35 patients (78%) undergoing OGR, 12 (27%) had prior hip replacement (75% via lateral approach). The OGRs had more patients with GFC ≥2 (50% vs 11%, P = .02) and used more anchors (P = .03). Both groups showed statistical improvement (P ≤ .01) for all outcomes measured. GFC >2 was independently associated with a worst limp and Harris Hip Score Section 1 score (P = .05). EGR had a statistically higher opioid use reduction (P < .05) than OGR. Other comparisons between EGR and OGR did not reach statistical significance. CONCLUSION In this series, open vs endoscopic operative approach did not impact clinical outcomes. More complex tears were treated open and with more anchors. Fatty degeneration adversely impacted outcomes. Although further evaluation of the efficacy of EGR in complex tears is indicated, both approaches can be used successfully.

Abstract
Abductor tendon tears are one of the common causes of recalcitrant laterally based hip pain and dysfunction. In most cases, abductor tendon tears are associated with chronic nontraumatic tearing of the gluteus medius tendon. Restoring abductor function of the hip by primary repair of the gluteus medius tendon has been reported to have good and excellent outcomes. However, primary repair might not be as effective for chronic detachment of the gluteus medius tendon with a wide separation from the femoral footprint or severe tendon loss. The lack of tendinous foot for repair and the intrinsically degenerative condition of the tendon may create high tension at the repair site thereby predisposing to surgical failure. We believe that the use of soft-tissue allograft from the Achilles tendon or human dermal allograft may help strengthen the surgical site. We describe a superior gluteal reconstruction technique that is suitable for cases with abductor tendon tear with severe tendon loss.

Abstract
Over the past decade, understanding of disorders compromising greater trochanteric pain syndrome (GTPS) has increased dramatically. Nonsurgical treatment options include physical rehabilitation and activity modification, anti-inflammatory as well as biologic injections into the peritrochanteric compartment, and administration of oral analgesics. Multiple open and endoscopic treatment options exist when nonsurgical management is unsuccessful in patients with refractory lateral-sided hip pain, with or without weakness. No true consensus exists within the literature regarding operative techniques of GTPS or postoperative rehabilitation protocols. We present an endoscopic classification system of GTPS with 5 distinct types, which seems to correlate well with preoperative diagnoses and postoperative rehabilitation protocols. The classification system is intuitive, and the corresponding surgical techniques are reproducible for surgeons treating peritrochanteric pathology. Level of Evidence: I (hip); II (extra-articular, impingement).

Abstract
Hip preservation is one of the fastest growing fields in orthopaedics and indications of intra-articular procedures are well established. In the last decade, extra-articular procedures have gained momentum and arthroscopic solutions to peri-articular hip pathologies have been offered. It should be noted that many of these pathologies are well-treated conservatively and only those who fail conservative management should be treated operatively. These indications can be divided into 5 categories: greater trochanteric pain syndrome; internal hip snapping; anterior inferior iliac spine/sub-spine impingement; sciatic nerve entrapment; and proximal hamstring injuries. This article reviews the anatomy, patient history and physical examination, imaging, non-operative treatment, endoscopic operative treatment and outcomes of each category. While indications for hip arthroscopy, specifically extra-articular procedures, are rising steadily, there is not enough data to support its superiority over open procedures. Current literature consists of case studies, case reports, and expert opinions and lacks large, randomised control studies.

Abstract
Lateral-based hip disease is severely impairing for many patients. Treatment decision making requires a thorough understanding of the biomechanical and clinical interpretation of the physical examination. The outcomes of these under-recognized pathologies are explained with success. A recent study has described the diagnostic and surgical treatment outcomes of this impairing condition of partial and full-thickness gluteus medius tears.
