Background

Identifying factors that predict a patient's willingness to undergo revision hip arthroscopy again can guide clinical decisions. This study focuses on the maximal outcome improvement threshold (MOWT) for revision surgery.

Methods

• Patients who underwent revision hip arthroscopy were included if they had follow-up data and baseline/postoperative PROMs.
• The study analyzed predictors of achieving the MOWT for three PROs: modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), and visual analog scale (VAS).
• Multivariate logistic regression identified factors associated with MOWT success.

Key Findings

• 77.3% of patients were willing to undergo revision surgery again if they reached the MOWT for mHHS, NAHS, and VAS.
• Patients with residual cam-type femoroacetabular impingement were 2.3 times more likely to achieve MOWT for VAS.

Conclusions

The MOWT for revision hip arthroscopy was defined for mHHS, NAHS, and VAS. Residual cam-type morphology before revision surgery was identified as a predictor for achieving favorable outcomes.

What Does This Mean For Patients

If you are considering revision hip arthroscopy, knowing that residual cam-type impingement can predict better outcomes may help guide your decision-making.
