Midterm Outcomes in Patients Aged 40 Years and Older With Borderline Dysplasia After Hip Arthroscopy for Femoroacetabular Impingement: A Propensity-Matched Analysis

This study concludes that patients with BHD aged ≥40 years treated with contemporary hip arthroscopy for FAIS achieved similar function, pain, and satisfaction at 5-year follow-up but worse sports function and sports-related PASS achievement when compared with patients with BHD aged <40 years. Furthermore, while patients ≥40 years old had a higher rate of total hip arthroplasty conversion, they demonstrated similar overall reoperation rates as compared with younger patients at 5 years.
