Revision hip arthroscopy yielded improved clinical outcome scores, high survivorship

Patients who underwent revision hip arthroscopy experienced improved clinical outcome scores for all patient-reported outcomes, high survivorship and high patient satisfaction scores at 2-year minimum follow-up, according to results.
Researchers prospectively collected data on 70 patients who underwent revision hip arthroscopy from April 2008 to October 2011. Researchers assessed patients preoperatively and postoperatively with the modified Harris Hip score, non-arthritis hip score, hip outcome score- activities of daily living (HOS-ADL) and hip outcome score–sport-specific subscales (HOS-SSS). Researchers also estimated pain on the VAS and measured patient satisfaction. They also reported the number of patients who underwent re-revision arthroscopy, total hip arthroplasty or a resurfacing procedure during the study period.

Results showed 45.7% of patients had preoperative alpha angles of 55° or greater and 7.14% of patients had a lateral center-edge angle of 40° or greater. Researchers found statistically significant improvements from preoperative outcomes to 2-year follow-up for the modified Harris Hip score (57.84 to 73.65), HOS-ADL score (62.79 to 83.04), HOS-SSS score (37.33 to 54.93) and for the non-arthritis hip score (55.65 to 70.79), as well as a significant decrease on the VAS of 6.72 to 4.08. According to results, patient satisfaction was 7.67 at latest follow-up, with 74.58% of patients reporting an overall satisfaction score of seven or higher.
Researchers noted a success rate of 74.58%, with 14.29% of patients subsequently undergoing total hip arthroplasty. Results showed a hip survivorship of 85.7%, with 7.14% of patients undergoing secondary revision hip arthroscopy. Overall, the minor complication rate was 10%. – by Casey Tingle
