Summary
Arthroscopic labral repair and selective labral debridement show comparable mid-term hip outcomes. Both procedures improved patient-reported scores, indicating similar effectiveness for hip labral tears.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Radiology
Background:
- Hip labral tears are a common source of hip pain and dysfunction.
- Arthroscopic surgical techniques aim to address labral pathology.
- Comparing repair versus debridement is crucial for treatment selection.
Purpose of the Study:
- To compare mid-term clinical outcomes of arthroscopic labral repair using looped sutures versus selective labral debridement.
- To evaluate patient-reported outcomes and imaging findings at a minimum 2-year follow-up.
Main Methods:
- Retrospective comparative study of 76 patients in the repair group and 76 matched controls in the debridement group.
- Matching criteria included age, sex, BMI, follow-up duration, and radiographic parameters.
- Pre- and post-operative 3D double-echo steady-state MRI and patient-reported outcome scores (Harris Hip Score, VAS, HOS-ADL, HOS-SSS) were assessed.
Main Results:
- Both groups showed significant improvement in patient-reported outcomes.
- The repair group improved from 0.6 ± 0.1 to 0.3 ± 0.1, and the debridement group improved from 0.3 ± 0.1 to 0.1 ± 0.1.
- No significant difference in final patient-reported outcomes was observed between the two groups.
Conclusions:
- Mid-term clinical outcomes are comparable between arthroscopic labral repair with looped sutures and selective labral debridement.
- Apparent gaps between the labrum and cartilage on MRI post-repair do not correlate with clinical outcomes.
- Both techniques offer effective mid-term relief for hip labral tears.
