The exclusion criterion was previous hip disorders (eg, Legg-Calve-Perthes disease, avascular necrosis). The control group contained patients with full-thickness gluteus medius tears on magnetic resonance imaging (MRI) who did not require operative intervention. Both groups had a minimum trial of 3 months of nonoperative management. Matching criteria included age within 5 years, sex, and body mass index (BMI) class. The following clinical parameters were analyzed: presence of lateral-sided hip pain, duration of symptoms, power of resisted hip abduction, gait deviation (antalgic or Trendelenburg), greater trochanter tenderness, and hip passive range of abduction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Twenty-four patients who underwent isolated endoscopic gluteus medius repairs were identified; all patients were females, with a mean age of 65 years (range, 52-82 years) and mean BMI of 29.2 kg\/m\n                      <jats:sup>2<\/jats:sup>\n                      (range, 21.55-44.398 kg\/m\n                      <jats:sup>2<\/jats:sup>\n                      ). The matched control cohort contained 12 females treated nonoperatively for gluteus medius tears with mean age of 66 years (range, 52-81 years) and mean BMI of 29.9 kg\/m\n                      <jats:sup>2<\/jats:sup>\n                      (range, 20.20-43.59 kg\/m\n                      <jats:sup>2<\/jats:sup>\n                      ). There were significant differences between the groups in power of resisted abduction and presence of gait deviation. The operative cohort had a mean power grading of 3.63 (95% CI, 3.28-3.98) compared with 4.58 (95% CI, 4.29-4.87) for the matched cohort ( P &lt; .05). Abnormal gait was found in 75% of the operative cohort, compared with 33% of the matched cohort ( P &lt; .05). Specifically, 83.3% of the surgical cohort had a Trendelenburg gait, compared with 25% of the matched cohort ( P = .002). The odds of requiring surgical intervention was 14-fold higher for patients with a gluteus medius tear and gait deviation compared with those without gait deviation. There were no significant differences in the other parameters.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Reduced power of resisted abduction and the presence of gait deviation on initial evaluation of patients with gluteus medius tears increases the likelihood of surgical intervention.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/2325967115571079","type":"journal-article","created":{"date-parts":[[2015,2,26]],"date-time":"2015-02-26T03:27:55Z","timestamp":1424921275000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":48,"title":["Clinical Features That Predict the Need for Operative Intervention in Gluteus Medius Tears"],"prefix":"10.1177","volume":"3","author":[{"given":"Sivashankar","family":"Chandrasekaran","sequence":"first","affiliation":[{"name":"American Hip Institute, Westmont, Illinois, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.
