Lei P, et al. - In these comparative studies obtained from PubMed, OVID, and Cochrane database, the authors evaluated 1129 subjects [819 cases in the femoroacetabular impingement (FAI) group and 310 cases in FAI with osteoarthritis (OA) group] to analyze the prognostic value of OA on the overall failure rate, pain, and function of surgical management of FAI. They noticed a correlation among radiographic OA and higher failure rates, increased conversion to total hip arthroplasty, and worse outcomes after surgical management of FAI.
