Hip Range of Motion Is Increased After Hip Arthroscopy for Femoroacetabular Impingement: A Systematic Review
It is generally accepted that decreased motion in patients with symptomatic FAI occurs primarily because of a mechanical block to movement from abnormal bony morphology of the proximal femur and/or acetabulum. This systematic review investigated the impact of arthroscopic correction of symptomatic femoroacetabular impingement on post-operative hip range of motion (ROM), as an objectively measured postoperative clinically reported outcome. Outcome studies demonstrate overall increased range of flexion and IR post-hip arthroscopy, with a moderate and large effect respectively. However, current research evaluating changes in this functional ability is limited by a lack of prospective studies and non-standardized measurement evaluation techniques.
