Arthroscopic Repair of the Hip Abductor Musculotendinous Unit: The Effect of Microfracture on Clinical Outcomes

Background: Endoscopic surgical repair has become a common procedure for treating patients with hip abductor tendon tears. Considering that retear rates are high after the of gluteus medius and minimus tendons, exploring alternative strategies to enhance structural healing is important. Purpose/Hypothesis: The purpose this study was evaluate effect adding microfracture single-row (SR) on outcomes tendons compare SR double-row (DR) without microfracture. We hypothesized trochanteric footprint would lead superior clinical lower clinically evident compared DR addition Study Design: Cohort study; Level evidence, 3. Methods: A total 50 who underwent primary arthroscopic tears were investigated. Patients divided into 3 groups: DR, 16 patients; SR, 14 (SRM), 20 patients. evaluated visual analog scale (VAS) pain as well Hip Outcome Score–Activities Daily Living (HOS-ADL), Score–Sport Specific (HOS-SS), modified Harris Score (mHHS) both preoperatively at minimum 2-year follow-up (mean, 30 months). Results: Among SRM, groups, greatest decrease in VAS scores increase mHHS, HOS-ADL, HOS-SS seen SRM group, all differences significant ( P < .001 = .006). 31.3%, 35.7%, 15.0% respectively. Retear group groups .042); however, there no difference between .32) terms rates. Conclusion: safe, practical, effective technique had potential advantage enhancing biological footprint. microfracturing significantly lowered rate provided better functional than
