Abstract
Hip abductor tears have recently gained recognition as a more prevalent injury than previously thought. This article will detail the pathophysiology of injury, physical symptoms commonly found at presentation, diagnostic imaging to best diagnose tears and when they should be ordered, and how to properly classify the injury and finally summarize the treatment options available with expert opinions about which are most successful.

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 Hip abductor complex tears remain an injury without a clear consensus on management. Surgical treatment has been recommended after unsuccessful nonoperative management. This study evaluates both tenodesis and bone trough techniques, with treatment choices guided by previously described tear classification. METHODS This is a retrospective cohort study of 45 hips in 44 patients who underwent surgical treatment for symptomatic, chronic hip abductor tear unresponsive to nonoperative treatment. Demographics and preoperative and postoperative values (including visual analog scale pain scores, gait assessment, and muscle strength) were evaluated. Type I tears were treated using tendon tenodesis. Type II tears were treated through a bone trough repair. RESULTS Forty-five hips (44 patients) were operated on with a minimum of 6-month follow-up. There were 27 type I and 18 type II tears. Eighty-seven percent of patients were female. Twenty-eight percent of type II patients (5/18) had a preexisting arthroplasty in place. Significant improvements in pain (P < .001), gait (P < .001), and muscle strength (P < .001) were achieved in both the tear types. Type I repairs showed superior results to type II repairs. However, both showed significant improvements. Postoperative magnetic resonance imaging at 6 months showed healed tenodesis in 81% (17/21) of type I tears and 50% (5/10) of type II tears. CONCLUSION Our study shows improvement in pain and function after surgical repair of hip abductor tendon injuries in both simple and complex tears. This improvement is seen even during ongoing surgical site healing. Magnetic resonance imaging findings may remain abnormal for more than 1 year after surgery and do not clearly denote repair failure.

Abstract
Avulsion injuries of the gluteus medius and gluteus minimus muscles represent a diagnostic and therapeutic challenge. Such injuries are rarely to be expected in high-energy trauma. Degenerative damage or iatrogenic injuries in the context of hip surgery are more frequently identified as the cause. Clinically, in addition to lateral hip pain, limping is an important finding and depends on the extent of the tendon damage. In addition to the medical history and clinical examination, imaging by means of sonography and, above all, magnetic resonance imaging (MRI, possibly with artifact-reduced sequences in the presence of an endoprosthesis) are diagnostically groundbreaking. Therapeutically, a stepwise approach is indicated according to the extent of rupture and quality of the gluteal tendon and muscle tissues. Specific conservative training regimens, mini-open/endoscopic anatomic reconstruction techniques in cases of gluteal muscle integrity and muscle transfer techniques as salvage option with chronic mass ruptures are available. The common goal is the restoration of everyday occupational and private activities to regain the quality of life.

Abstract
PURPOSE Abductor tendon tears are increasingly recognised as a common cause of lateral hip pain. Surgical treatment of these tears has been recommended, but the indications and types of open surgery have not been precisely elucidated yet. This manuscript aimed to critically review the literature concerning all open treatment options for this condition while identifying knowledge gaps and introducing a treatment algorithm. METHODS Literature search was conducted, including PubMed, Cochrane library, ScienceDirect and Ovid MEDLINE from 2000 to May 2020. Inclusion criteria were set as: (i) clinical studies reporting outcomes following open surgical treatment of acute or chronic hip abductor tendon tears, (ii) studies reporting an open direct or augmented suturing or muscle transfer procedure, (iii) acute or chronic tears found in native or prosthetic hips. RESULTS A total of 34 studies published between 2004 and 2020 were included. The vast majority of studies were uncontrolled case series of a single treatment method. A total of 970 patients (76% women) with an age range between 48 and 76 years were involved. Women between 60 and 75 years old were most commonly treated. Preoperative evaluation of patients and reporting of open surgical technique and outcomes are inconsistent. All studies reported variable improvement of pain, functional outcomes and gait of patients. Overall, complication rates ranged from 0 to 31.2%. CONCLUSION The current literature on this topic is highly heterogeneous, and the overall level of the available evidence is low. A roadmap to develop practical guidelines for open surgery of acute and chronic tears of abductor tendons is provided. The anatomy and chronicity of the lesion, the extent of fatty infiltration and neurologic integrity of hip abductor muscles may influence both treatment choice and outcome. Further high-quality studies with standardisation of preoperative evaluation of patients and reporting of outcomes will help delineate best treatments. LEVEL OF EVIDENCE IV.

Abstract
Gluteal insufficiency or hip abductor mechanism deficiency mainly following (revision) total hip replacement is associated with highly painful complaints and severe suffering of patients. It represents a great diagnostic and therapeutic challenge. Differentiated conservative treatment pathways, open surgical and endoscopic anatomic repair techniques with intact gluteal musculature and muscle transfer are available as salvage procedures for chronic not anatomically reconstructable mass ruptures. A stepwise diagnostic and therapeutic approach is required for restoration of the quality of life and painless or almost painless mobility of affected patients in occupation and daily life.

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
Hip abductor tendon tears are a well-recognized entity that results in progressive lateral hip pain, weakness, and limping. These can occur in patients with native hips or in patients following total hip arthroplasty. However, treatment of these 2 distinct groups does not differ. We describe a new repair technique utilizing a longitudinal bone trough in the greater trochanter. We compare our results (focusing on gluteus medius tendon avulsions) and traditional repair with suture anchors or transosseous bone tunnels. Additionally, we propose a classification system that attempts to describe the different types of tears to guide treatment, as the current classification system is not helpful in defining pathology or guiding treatment. Our proposed classification will help to better describe tear types anatomically and thereby guide appropriate surgical interventions based on these types.

Abstract
Background: Hip abductor tendon (HAT) tearing is commonly implicated in greater trochanteric pain syndrome. Studies reporting surgical outcomes are often on small cohorts and with limited information on functional improvement. Purpose: To report the 2-year clinical and functional outcomes in a series of patients undergoing HAT repair augmented with a ligament augmentation and reconstruction system (LARS) ligament. Study Design: Case series; Level of evidence, 4. Methods: Between October 2012 and December 2016, a total of 142 patients with symptomatic HAT tears underwent open bursectomy, V-Y lengthening, and reattachment of the tendon with suture anchors augmented with a LARS ligament. This included 132 women (93%) with a mean age of 64.3 years (range, 43-84 years), a mean body mass index of 28.2 kg/m2 (range, 20.0-41.3 kg/m2), and an average duration of symptoms of 4.0 years (range, 6 months-20 years). Following surgery, patients underwent a graduated rehabilitation program consisting of hydrotherapy and land-based exercises. Patient-reported outcome measures (PROMs) were evaluated preoperatively and at 3, 6, 12, and 24 months postoperatively with the Harris Hip Score, Oxford Hip Score, 12-item Short Form Health Survey, and visual analog scale (VAS) for pain. Hip range of motion, hip abduction strength, 30-s single-leg stance (SLS), and 6-minute walk test (6MWT) capacity were evaluated. Patient satisfaction and perceived global rating of change were evaluated postsurgery. Analysis of variance was employed to evaluate clinical improvement over time. Results: A significant improvement (P < .05) was demonstrated up to 24 months in all PROMs and clinical scores, including hip range of motion in all planes, hip abductor strength limb symmetry indices (mean ± SD; presurgery, 90.1% ± 42.5%; 24 months, 102.6% ± 15.0%), and the 6MWT (presurgery, 421.8 ± 91.9 m; 24 months, 509.7 ± 105.1 m). Furthermore, several variables, including pain (VAS and pain scores during the 6MWT and 30-s SLS) and patient-perceived improvement (global rating of change), continued to improve from 12 to 24 months. At 24 months, 95.7% of patients were satisfied with their surgical outcome (excluding 3 patients who underwent reoperation within the 24-month period). There was a 5.6% (n = 8) failure rate over the study period. Conclusion: HAT repair augmented with a synthetic ligament demonstrated significantly improved clinical and functional outcomes, high levels of patient satisfaction, and a relatively low failure rate up to 24 months postsurgery.

Abstract
BACKGROUND Extensive tearing of the gluteus muscles (spontaneous or subsequent to hip arthroplasty) is difficult to treat. We are carrying out osseous fixation with securement of the suture anchor by a nonresorbable collagen patch. The objective of this study is to examine the follow-up data of 30 patients and to assess whether the clinical outcomes depended on the extent of the fatty degeneration of the gluteus medius. METHODS Thirty patients (28 female and 2 male) with a mean age of 76.8 ± 4.3 years (68-83 years) were followed for a mean of 46.8 ± 23.1 months (24-101 months). RESULTS Pain improved significantly from a preoperative visual analog scale score of 7.0 ± 1.52 (6-10) to 0.83 ± 0.77 (0-3) 24-month postoperative. The gluteus medius muscle force increased from 2.09 ± 0.81 to 3.3 ± 0.78 using the British Medical Research Council Scale. All patients exhibited a severe limp before the operation. Postoperatively, only 5 patients had a severe limp, while 14 exhibited a mild limp and 11 no limp at all. The modified Harris Hip Score increased from a preoperative value of 44.5 ± 4.2 (26-66) to a value of 81.1 ± 7.79 (60-100) 24-month postoperative. The functional results were dependent on the level of fatty degeneration of the muscle. CONCLUSION The first results for this surgical technique appear to be very promising for the treatment of extensive tearing of the gluteus musculature that has a degree of fatty degeneration less than 75%.

Abstract
INTRODUCTION Hip abductor tendon (HAT) tearing is commonly implicated in greater trochanteric pain syndrome. Surgical studies are often reported in small cohorts and with limited information on functional improvement. This study reports the clinical and functional outcomes after HAT repair. METHODS 112 patients with symptomatic HAT tears, diagnosed via magnetic resonance imaging, underwent open bursectomy, V-Y lengthening of the iliotibial band, debridement of the diseased tendon, decortication of the trochanteric foot-plate and reattachment of the tendon with suture anchors, augmented with a LARS ligament through a trans-osseous tunnel. Patients were evaluated pre-surgery and at 3, 6 and 12 months post-surgery using the Harris (HHS) and Oxford (OHS) Hip Scores, SF-12, hip range of motion, 6-minute walk and 30-second single leg stance tests. Maximal isometric hip abduction strength (HAS) was assessed and limb symmetry indices (LSIs) were calculated between the operated and non-operated limbs. Patient satisfaction and perceived global rating of change (GRC) was evaluated. Analysis of variance evaluated improvement over time. RESULTS There was a significant improvement (p<0.05) in all clinical and functional measures. HAS significantly improved over time (p<0.002) and all LSIs were >85% at 12 months. At 12 months, a mean GRC score of 3.5 (range -1 to 5) was reported, while 96% of patients were satisfied with their surgical outcome. There was a 2.7% (n = 3) failure rate at 12 months. CONCLUSIONS HAT reconstruction, augmented with a synthetic ligament, demonstrated significantly improved clinical and functional outcomes, high levels of patient satisfaction and a low failure rate to 12 months post-surgery.

Abstract
BACKGROUND Hip abductor tendon tears are a common cause of Greater Trochanteric Pain Syndrome. Conservative treatments are often ineffective and surgical reconstruction may be recommended. This study investigated the improvement in clinical outcomes and frontal plane two-dimensional biomechanics during a 30-second single leg stance test, in patients undergoing reconstruction. We hypothesized that clinical scores and pertinent biomechanical variables would significantly improve post-surgery, and these outcomes would be significantly correlated. METHODS Twenty-one patients with symptomatic tendon tears underwent reconstruction. Patients were evaluated pre-surgery, and at 6 and 12months post-surgery, using patient-reported outcome measures, assessment of hip abductor strength and six-minute walk capacity. Frontal plane, two-dimensional, biomechanical variables including pelvis-on-femur angle, pelvic drop, trunk lean and lateral pelvic shift, were evaluated throughout a 30-second single leg stance test. ANOVA evaluated outcomes over time, while Pearson's correlations investigated associations between clinical scores, pain, functional and biomechanical outcome variables. FINDINGS While clinical and functional measures significantly improved (P<0.05) over time, no significant group differences (P>0.05) were observed in biomechanical variables from pre- to post-surgery. While five patients displayed a positive Trendelenburg sign pre-surgery, only one was positive post-surgery. Clinical outcomes and biomechanical variables during the single leg stance test were not correlated. INTERPRETATION Despite improvements in clinical and functional measures over time, biomechanical changes during a weight bearing single leg stance test were not significantly different following tendon repair. Follow up beyond 12months may be required, whereby symptomatic relief may precede functional and biomechanical improvement.

Abstract
Abductor tendon tears typically develop insidiously in middle-aged women and can lead to debilitating lateral hip pain and a Trendelenburg limp. The gluteus medius tendon is most commonly torn and may show fatty degeneration over time, similar to the rotator cuff muscles of the shoulder. Endoscopic repair offers a therapeutic alternative to traditional open techniques. This article describes the workup, examination, and endoscopic repair of a full-thickness gluteus medius tear presenting as lateral hip pain and weakness. The surgical repair for this case used a single-row suture anchor technique. In addition, the indications and technique for a double-row repair will be discussed.

Abstract
Advanced hip imaging and surgical findings have demonstrated that a common cause of greater trochanteric pain syndrome (GTPS) is gluteal tendon tears. Conservative measures are initially employed to treat GTPS and manage gluteal tears, though patients frequently undergo multiple courses of non-operative treatment with only temporary pain relief. Therefore, a number of surgical treatment options for recalcitrant GTPS associated with gluteal tears have been reported. These have included open trans-osseous or bone anchored suture techniques, endoscopic methods and the use of tendon augmentation for repair reinforcement. This review describes the anatomy, pathophysiology and clinical presentation of gluteal tendon tears. Surgical techniques and patient reported outcomes are presented. This review demonstrates that surgical repair can result in improved patient outcomes, irrespective of tear aetiology, and suggests that the patient with "trochanteric bursitis" should be carefully assessed as newer surgical techniques show promise for a condition that historically has been managed conservatively.

Abstract
BACKGROUND Gluteus medius tears may be present in as many as 25% of late middle-aged women and 10% of middle-aged men, and they are often misdiagnosed. Outcomes of endoscopic repair of gluteus medius tears have seldom been reported. PURPOSE To report the early outcomes of endoscopic repair of partial- and full-thickness gluteus medius tears. STUDY DESIGN Case series; Level of evidence, 4. METHODS Between April 2009 and January 2010, data were prospectively collected for all patients undergoing endoscopic gluteus medius repair by one of the authors. Inclusion criteria for the study were patients undergoing repair for either high-grade, partial-, or full-thickness tears. Only patients with endoscopic evidence of a gluteus medius tear were treated surgically. In the case of an articular-side tear, a transtendinous repair technique was used, whereas in the presence of a full-thickness tear, the tendon was refixated to the bone directly. RESULTS A total of 15 patients met the inclusion criteria. The cohort included 14 women and 1 man, with an average age of 58 years (range, 44-74 years). Endoscopically, 6 cases were found to be partial-thickness tears. Nine were either full-thickness tears or near-full-thickness tears, which were completed for the repair. Follow-up was obtained on all patients at an average of 27.9 months postoperatively (range, 24-37 months). Fourteen of the 15 patients showed postoperative improvement in all 4 hip-specific scores used to assess outcome, with an average improvement of more than 30 points for all scores. Satisfaction with the surgery results was reported to be from good to excellent (scores of 7-10 out of 10) in 14 of 15 patients. CONCLUSION This study demonstrates that endoscopic surgical repair, whether performed through a transtendinous or full-thickness technique, can be an effective treatment of gluteus medius tears at a minimum follow-up of 2 years. Longer term follow-up studies are necessary to determine whether these therapeutic and functional gains are maintained.
