Background

Labral tears that cannot be repaired may require circumferential acetabular labral reconstruction, especially in revision hip arthroscopy cases. This study evaluates the effectiveness of this procedure by examining patient-reported outcomes (PROs) and the rate of achieving the minimal clinically important difference (MCID) after a minimum of two years.

Methods

This study reviewed 26 patients who underwent circumferential labral reconstruction as part of revision hip arthroscopy. They were assessed preoperatively and at a minimum 2-year follow-up using various outcome measures like the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), and visual analog scale (VAS) for pain.

Key Findings

Significant improvements were seen in all PROs, including mHHS (17-point improvement), NAHS (18-point improvement), and VAS for pain (2.2-point improvement). The rates of achieving MCID were 76.9% for mHHS and 80% for NAHS. Only one patient required conversion to total hip arthroplasty at 38.6 months.

Conclusions

Circumferential labral reconstruction for revision hip arthroscopy leads to significant improvements in hip function and pain. The high MCID achievement rate suggests this procedure is effective in addressing irreparable labral tears.

What Does This Mean for Patients

If you require a revision hip surgery for irreparable labral tears, circumferential labral reconstruction can provide meaningful improvements in hip function and reduce pain over time.
