The anterior-based muscle-sparing (ABMS) approach, using the intramuscular interval between the tensor fascia lata and gluteus medius, is an increasingly popular total hip arthroplasty (THA) approach. Its incidence of lateral femoral cutaneous nerve (LFCN) numbness has not been defined. The incidence of LFCN symptoms in direct anterior THA ranges from 7%-32% at 1-year follow-up. The purpose of this study is to determine the incidence of LFCN symptoms in patients who underwent ABMS THA at 1-year follow-up.
