Hip arthroscopic labral reconstruction shows significant clinical outcomes comparable to labral repair at 2-year follow-up. Both procedures improved patient-reported outcomes and reduced pain, with similar complication rates.
Area of Science:
- Orthopedic Surgery
- Arthroscopy
- Hip Preservation
Background:
- Hip labral tears are a common source of pain and dysfunction.
- Arthroscopic surgical techniques, including labral repair and reconstruction, aim to restore hip joint function.
- Comparative outcome data between labral reconstruction and repair are essential for guiding clinical decision-making.
Purpose of the Study:
- To compare the clinical outcomes of arthroscopic hip labral reconstruction versus a pair-matched labral repair group.
- To evaluate patient-reported outcomes (PROs) and pain at a minimum 2-year follow-up.
- To assess complication rates and the need for secondary procedures.
Main Methods:
- Retrospective comparative study including patients undergoing arthroscopic hip labral reconstruction with at least 2-year follow-up.
- Reconstruction patients were pair-matched 1:2 to labral repair patients based on age, sex, BMI, capsular treatment, and chondral damage.
- Three PROs and visual analog scale (VAS) for pain were assessed preoperatively and postoperatively; patient satisfaction and International Hip Outcome Tool were collected at latest follow-up.
Main Results:
- Thirty-four reconstruction patients were matched to 68 repair patients with no significant demographic differences.
- Both groups showed statistically significant improvements in all PROs and a significant decrease in VAS pain scores at 2-year follow-up.
- No significant differences were observed in postoperative complications, secondary arthroscopy rates, or conversion to total hip arthroplasty between the groups.
Conclusions:
- Arthroscopic hip labral reconstruction leads to significant improvements in PROs and has a low incidence of secondary surgery within 2 years.
- Outcomes, including PROs, VAS pain, patient satisfaction, and secondary procedures, were comparable between labral reconstruction and repair.
- Either labral repair or reconstruction can be considered based on the clinical scenario, as outcomes were similar in this matched cohort.
