Editorial Commentary: Hip Capsule: To Repair or Not?

Abstract

Arthroscopic hip capsular repair is an area of intense interest. Basic science studies suggest that adverse changes in capsular stability/restraint may occur with capsulotomy and capsulectomy, that repair may ameliorate these changes, and, most recently, that the repaired capsule usually heals. Clinical studies suggest that in some conditions, most notably mild dysplasia, capsular repair or plication may improve short-term outcomes, but in general, the role of capsular closure is less clear. At present, perhaps a selective approach is merited, with capsular closure performed in patients with dysplasia, focal or generalized hyperlaxity, and/or increased femoral anteversion. The comparative outcomes from smaller, more vertically oriented capsulotomies with less violation of the iliofemoral ligament deserve investigation.
