[Purpose] Public attention regarding sarcopenia has increased in recent years. Patients with sarcopenia reportedly show worse return home rates and activities of daily living at discharge. However, no reports have described the function and outcomes of hip osteoarthrosis patients with sarcopenia after total hip arthroplasty. This study aimed to clarify differences in preoperative physical function and outcomes of hip osteoarthrosis patients with versus without sarcopenia after total hip arthroplasty. [Participants and Methods] Twenty-five patients with hip osteoarthrosis who underwent total hip arthroplasty were included. Evaluation items were preoperative skeletal muscle mass of the extremities, isometric strength of the lower extremities (hip abduction and knee extension), grip strength, and the 10-m timed gait test results. [Results] The prevalence of sarcopenia was 8% (2/25 patients). The sarcopenic group displayed lower skeletal muscle mass index, grip strength, and 10-m timed gait test values. The sarcopenic group showed lower muscle mass in the upper and lower limbs and trunk and lower hip abductor strength than the non-sarcopenic group. [Conclusion] Eight percent of patients developed sarcopenia after total hip arthroplasty. Due to the low average age (66.0 ± 9.5 years), the prevalence was lower than that of other orthopedic diseases.
