Sexual Dimorphic Features Associated with Femoroacetabular Impingement.

Sexual dimorphism describes differences in biologic response between males and females due to inherent chromosomal differences. These differences similarly affect orthopaedic-related injuries and treatment outcomes as seen with femoroacetabular impingement, an abnormal hip morphology where females have shown worse hip function scores than male counterparts before and after surgery. Potential dimorphic factors that increase susceptibility of females to injury and/or worse outcomes may include joint laxity, hip morphology, and osseous biology. This article reviews the relevant literature of prevalence, presentation, management, and outcomes that characterize sexual dimorphism as it relates to femoroacetabular impingement.
