title: Endoscopic repair of gluteus medius tendon tears of the hip.
abstract: BACKGROUND
  Tears of the gluteus medius tendon at the greater trochanter have been termed "rotator cuff tears of the hip." Previous reports have described the open repair of these lesions.
  
  
  OBJECTIVE
  Endoscopic repair of gluteus medius tears results in successful clinical outcomes in the short term.
  
  
  METHODS
  Case series; Level of evidence, 4.
  
  
  METHODS
  Of 482 consecutive hip arthroscopies performed by the senior author, 10 patients with gluteus medius tears repaired endoscopically were evaluated prospectively. Perioperative data were analyzed on this cohort of patients. There were 8 women and 2 men, with an average age of 50.4 years (range, 33-66 years). Patients had persistent lateral hip pain and abductor weakness despite extensive conservative measures. Diagnosis was made by physical examination and magnetic resonance imaging and was confirmed at the time of endoscopy in all cases. At the most recent follow-up, patients completed the Modified Harris Hip Score and Hip Outcomes Score surveys.
  
  
  RESULTS
  At an average follow-up of 25 months (range, 19-38 months), all 10 patients had complete resolution of pain; 10 of 10 regained 5 of 5 motor strength in the hip abductors. Modified Harris Hip Scores at 1 year averaged 94 points (range, 84-100), and Hip Outcomes Scores averaged 93 points (range, 85-100). There were no adverse complications after abductor repairs. Seven of 10 patients said their hip was normal, and 3 said their hip was nearly normal.
  
  
  CONCLUSIONS
  With short-term follow-up, endoscopic repair of gluteus medius tendon tears of the hip appears to provide pain relief and return of strength in select patients who have failed conservative measures. Further long-term follow-up is warranted to confirm the clinical effectiveness of this procedure.
