Biomechanical Evaluation of Capsulotomy and Capsular Repair in the Hip

摘要

Objectives:The use of hip arthroscopy has increased over recent years to treat various forms of hip pathologies including femoroacetabular impingement. While a capsulotomy facilitates adequate visualization and access for diagnostic and interventional purposes, the current literature remains divided over the use of routine capsular closure to address the iatrogenic instability that may be induced by an excessive or unclosed capsulotomy. The purpose of this biomechanical study was to determine if hip capsulotomy creates significant alterations in rotational range of motion and stability measures. Additionally, does a capsular repair return these variables to normal?
