Purpose
To evaluate clinical outcomes, pain, and patient satisfaction after revision hip arthroscopy with a minimum of 2-year follow-up.
Methods
- Prospective collection of data from revision hip arthroscopy patients (April 2008–October 2011).
- Assessed pre- and postoperatively with four patient-reported outcome (PRO) measures: modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), Hip Outcome Score - Activities of Daily Living (HOS-ADL), and Hip Outcome Score - Sport-Specific Subscale (HOS-SSS).
- Pain measured by Visual Analog Scale (VAS); patient satisfaction rated 0-10.
- Recorded further surgeries including subsequent revisions or total hip arthroplasty (THA).
Key Findings
- 70 patients included; average follow-up 28 months.
- Significant improvements in all PROs:
- mHHS: 57.84 → 73.65
- HOS-ADL: 62.79 → 83.04
- HOS-SSS: 37.33 → 54.93
- NAHS: 55.65 → 70.79
- VAS pain decreased from 6.72 to 4.08.
- Patient satisfaction averaged 7.67/10.
- Success rate: 74.58%; hip survivorship: 85.7%.
- 14.29% converted to THA; 7.14% underwent secondary revision arthroscopy.
- Minor complication rate: 10%.
Conclusion
Revision hip arthroscopy leads to significant clinical improvements and high patient satisfaction in the short term but patients should be counseled on the risk of progression to arthroplasty or additional revision surgery.
What This Means for Patients
If you require a second hip arthroscopy, outcomes generally improve pain and function, but some patients may still need hip replacement or further surgery in the future.
