Epidemiological Characteristics and Factors Affecting Baseline Hip Function in Chinese Patients Undergoing Arthroscopic Treatment for Femoroacetabular Impingement Syndrome

The cohort of Chinese patients undergoing arthroscopic treatment for FAIS primarily comprised young and middle-aged adults, with a balanced sex distribution. Male patients had a larger alpha angle, higher prevalence of cam-type deformities, and higher proportion of cartilage lesions in the femoral head and acetabulum compared with female patients. Older age and female sex were associated with inferior baseline hip function.
