Background
Patient-reported outcome measures (PROs), pain, and satisfaction are commonly used to assess success after hip arthroscopy, but their interrelationships are not well defined.
Methods
In this prospective study of 1,137 patients, correlations were evaluated between VAS for pain and satisfaction and 4 PROs (mHHS, NAHS, HOS-SSS, HOS-ADL) at 2 years post-op.
Key Findings
All PROs and VAS improved significantly. VAS improvement averaged 2.9 points; patient satisfaction averaged 7.74/10. There was a moderate but statistically significant correlation between VAS, satisfaction, and the four PROs.
Conclusions
Pain relief and satisfaction moderately correlate with improvements in standard hip outcome scores, suggesting that they provide complementary value in evaluating surgical success.
What Does This Mean for Patients
Pain levels and satisfaction scores can help reflect outcomes after surgery but should be interpreted alongside comprehensive hip-specific functional scores.
