Five-Year Functional Outcomes After Acetabular Labral Repair with and without Bone Marrow Aspirate Concentrate

Area of Science:

• Orthopedic Surgery
• Regenerative Medicine
• Sports Medicine

Background:

• Hip arthroscopy for labral tears with cartilage damage often seeks improved functional outcomes.
• Previous studies on Bone Marrow Aspirate Concentrate (BMAC) augmentation have not extended beyond 24 months.
• This study evaluates the 5-year functional outcomes of BMAC augmentation in hip arthroscopy.

Purpose of the Study:

• To compare minimum 5-year functional outcomes in patients undergoing acetabular labral repair with or without BMAC augmentation.
• To assess the long-term efficacy of BMAC in addressing chondral damage during hip arthroscopy.

Main Methods:

• Prospective cohort study of patients undergoing arthroscopic acetabular labral repair by a single surgeon.
• Patients were divided into BMAC cohort and control cohort.
• Patient-reported outcome measures (PROMs) were collected preoperatively and at 3, 6, 12, 24, and 60 months postoperatively.

Main Results:

• Eighty-one hips were analyzed (39 BMAC, 42 control) with similar baseline characteristics.
• No significant differences in PROMs were observed between groups up to 12 months.
• BMAC group showed significantly higher scores for mHHS, iHOT-33, and HOS-ADL at 24 months and for mHHS, iHOT-33, and HOS-SS at 60 months.

Conclusions:

• Acetabular labral repair augmented with BMAC leads to significantly greater functional improvements compared to repair alone.
• These benefits become statistically significant at 24 months and continue to increase through 60 months.
• BMAC augmentation appears to offer favorable, extended functional benefits in hip arthroscopy patients.
