Purpose

To assess patient-reported outcomes and satisfaction 2 years after primary hip arthroscopy performed at a high-volume referral center.

Methods

Prospective case series including 595 patients undergoing primary hip arthroscopy from 2008 to 2011. Pre- and postoperative evaluations included modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Scores (HOS-ADL and HOS-SSS), Visual Analog Scale (VAS) for pain, and satisfaction scores.

Key Findings

• All PRO scores showed statistically significant improvements at 2 years:
• mHHS improved from 61.29 to 82.02
• HOS-ADL improved from 62.79 to 83.05
• HOS-SSS improved from 40.96 to 70.07
• NAHS improved from 57.97 to 80.41
• VAS pain decreased from 5.86 to 2.97 (P < .0001 for all)
• Patient satisfaction averaged 7.86/10.
• 7.7% underwent revision surgery, 9.1% converted to total hip arthroplasty or resurfacing.
• Increased age and certain surgical factors were associated with higher failure rates.

Conclusion

Primary hip arthroscopy provides significant pain relief and functional improvement at short-term follow-up with a low complication rate, but patients should be counseled about the potential need for revision or conversion to arthroplasty.

What This Means for Patients

Patients undergoing hip arthroscopy can expect meaningful improvements in pain and function within 2 years, though older patients and those with certain risk factors may have increased chances of requiring additional surgery.
