Key takeaways:
- Hip arthroscopy with capsular repair yielded a 91% survivorship rate at 10-year follow-up.
- Capsular repair may be preferred for patients with increased risks for conversion to arthroplasty.
Patients who underwent primary hip arthroscopy with capsular repair for femoroacetabular impingement had high rates of survivorship at 10 years, according to published results.
Benjamin G. Domb, MD, and colleagues at the American Hip Institute Research Foundation retrospectively reviewed prospectively collected data on 130 patients (145 hips; mean age, 30.3 years) with femoroacetabular impingement who underwent primary hip arthroscopy with capsular repair between October 2008 and February 2011.
Domb and colleagues assessed survivorship, patient-reported outcomes, modified Harris Hip Score (mHHS), nonarthritic hip score (NAHS), VAS pain scores and hip outcome score-sport specific subscale (HOS-SSS) at a minimum follow-up of 10 years.
At 10 years, survivorship was 91% with significant improvements in mHHS, NAHS, VAS pain and HOS-SSS scores in all patients. Researchers noted the minimal clinically important difference was achieved by 82.4% of patients for mHHS and 80.6% of patients for VAS pain scores.
According to the study, patients who underwent capsular repair had a 10-year survivorship rate of 82.8%, while patients who did not undergo capsular repair had a 10-year survivorship rate of 65.4%.
After analyzing a propensity-matched subgroup of patients with the highest risk for conversion to total hip arthroplasty, researchers found patients who did not undergo capsular repair had a trend toward higher rates of conversion to THA compared with patients who underwent capsular repair.
“Technological advancements that have allowed better and more efficient closures, as well as methods that have both improved closures and allowed the option to plicate [or] shift the capsule, play a major role in hip stability,” the researchers wrote in the study.

The study published by Benjamin G. Domb, MD, and colleagues is one of the first series looking at the long-term outcomes after hip arthroscopy for the treatment of femoroacetabular impingement syndrome undergoing capsular repair. The treatment of femoroacetabular impingement syndrome has evolved in the past decade, and the contemporary treatment incorporates chondrolabral repair, surgical correction of hip impingement and capsular repair. Prior studies reported that when hip arthroscopy is performed without capsular repair, the revision surgery rate or conversion to total hip replacement can be higher than that with capsular repair in short-term outcomes.
Patients with symptomatic femoroacetabular impingement syndrome who have failed conservative treatment without confounding factors (such as dysplasia, osteoarthritis or revision surgery) have excellent outcomes with low rates of revision surgery.
