Clinical Report: PROM Thresholds May Clarify Hip Arthroscopy Outcomes

Overview

This systematic review identifies clinically meaningful thresholds for patient-reported outcome measures following hip arthroscopy for femoroacetabular impingement.

Background

Understanding patient-reported outcome measures (PROMs) is crucial for evaluating the effectiveness of surgical interventions like hip arthroscopy. Clinically meaningful thresholds such as minimal clinically important difference (MCID) and patient-acceptable symptom state (PASS) help clinicians assess whether changes in patient status are significant. This review synthesizes existing literature to provide reference values for these thresholds.

Data Highlights

MeasureMCIDPASSSCBMIC
Modified Harris Hip Score14.670.794.08.0
Hip Outcome Score (ADL)14.875.296.65.0
International Hip Outcome Tool-3325.166.285.910.0

Key Findings

  • The review included 21 studies with a total of 5,687 patients.
  • Average MCID for the modified Harris Hip Score was found to be 14.6.
  • Variability in threshold values was noted due to different calculation methods used across studies.
  • Most studies reported high levels of patient satisfaction following hip arthroscopy.
  • Thresholds should be interpreted cautiously and not applied universally across all patient populations.

Clinical Implications

Thresholds should be interpreted cautiously and not applied universally across all patient populations.

Conclusion

The review provides reference values for PROM thresholds following hip arthroscopy.
