Background

Patient-reported outcome scores (PROs) such as the modified Harris Hip Score (mHHS) and iHOT-12 assess recovery after hip arthroscopy. The predictive value of failing to meet threshold scores for these PROs on subsequent surgical interventions is unclear.

Methods

Evaluation of patients undergoing primary hip arthroscopy, correlating 1-year PRO thresholds with incidence of secondary operations (revision surgery or total hip arthroplasty).

Key Findings

• Patients not reaching defined thresholds for mHHS and iHOT-12 at 1 year post-op showed a significantly higher risk of requiring secondary surgeries.
• The iHOT-12 score demonstrated a particularly strong association with the need for further operative intervention.

Conclusions

Failure to meet threshold scores on hip outcome measures at 1 year post-arthroscopy correlates with increased likelihood of secondary surgery.

What Does This Mean for Providers?

Monitoring mHHS and iHOT-12 scores at 1-year post-op is valuable for early identification of patients at risk for further surgery. Providers can use these metrics to guide closer surveillance, patient counseling, and potentially early intervention.
