Recently published results showed significant improvements in outcome scores for patients who underwent revision hip arthroscopy. However, the outcome scores were lower compared with patients who underwent primary hip arthroscopy.

Researchers matched 246 patients undergoing revision hip arthroscopy with 492 patients undergoing primary hip arthroscopy and collected hip outcome score–activities of daily living subscale (HOS-ADL), modified Harris Hip score (mHHS), WOMAC index, hip outcome score–sports subscale (HOS-Sports) and SF-12 scores preoperatively and at a minimum follow-up of 2 years. Researchers also collected Tegner activity scale scores and patient self-reported satisfaction with surgical outcome scores at follow-up.

Results showed subsequent hip arthroscopy and subsequent surgery were reported by 8% and 10% of patients, respectively, in the primary cohort vs. by 2% and 6% of patients, respectively, in the revision cohort. From preoperative measures to follow-up, researchers found significant improvement in outcome scores in both groups; however, patients in the revision cohort had lower preoperative HOS-ADL, HOS-Sports, WOMAC and SF-12 physical component scores. Although a higher postoperative mHHS was found among patients with one prior hip arthroscopy vs. patients who had more than one hip arthroscopy, researchers noted no difference between patients in the single-revision cohort and the primary cohort for postoperative mHHS. According to results, greater joint space was found among patients in the revision group whose HOS-ADL improved by 10 or more points. Researchers found patients with a previous labral tear that was not repaired and who required capsular plication at revision were more likely to experience greater improvement. – by Casey Tingle
