Endoscopic Repair of Partial-Thickness Undersurface Tears of the Abductor Tendon: Clinical Outcomes With Minimum 2-Year Follow-up.
Abstract: To report the minimum 2-year outcomes of transtendinous repair of partial-thickness undersurface tears of the abductor tendon using patient-reported outcomes (PROs), visual analog scale (VAS) scores, and patient satisfaction scores.
Methods: All patients who underwent endoscopic transtendinous gluteus medius repair between October 2009 and May 2013 at 1 institution were prospectively evaluated. The exclusion criteria consisted of less than 2 years' follow-up, previous hip surgery, inflammatory arthritis, open surgery, full-thickness abductor tear, and Workers' Compensation patients. All patients underwent a documented preoperative physical examination with strength testing (scale of 0-5) and observation of their gait. Patient satisfaction and PRO scores were recorded preoperatively; at 3 months postoperatively; and at 1, 2, 5, and 10 years after surgery. The PRO scores collected were the modified Harris Hip Score, Hip Outcome Score-Activities of Daily Living Subscale, Hip Outcome Score-Sports-Specific Subscale, Non-arthritis Hip Score, and VAS score. Preoperative strength and gait were compared with latest follow-up.
