Abstract Perspective: Hip Capsular Management in Patients with Femoroacetabular Impingement or Microinstability: A Systematic Review of Biomechanical Studies


This systematic review investigated the biomechanical effects of different hip capsular management strategies in the setting of femoroacetabular impingement and microinstability. There has been a debate in hip arthroscopy regarding capsular management and specifically if the capsule needs to be repaired or if it can be left unrepaired. Further, if the capsule is insufficient to repair, new techniques such as capsular reconstruction have been proposed to restore stability. Ultimately, the study included a total of 24 studies which focused on several different biomechanical parameters such as rotation, femoral head translation, rotational torque, and distraction force. The review found that repair of the capsule and capsular reconstruction demonstrated significant improvements in maximum distractive force, total range of motion, and torsional stability. The results of this review provide biomechanical evidence to support routine capsular repair after hip arthroscopy. In the setting of capsular insufficiency, early data suggests that capsular reconstruction demonstrates favorable results in restoring native kinematics.
