Prevalence and Preoperative Demographic and Radiographic Predictors of Bilateral Femoroacetabular Impingement

Abstract

Male sex, younger age, higher alpha angles, and reduced acetabular anteversion at initial presentation are significant risk factors for identifying patients who may ultimately require bilateral surgery for symptomatic FAI. Among bilaterally treated patients, no radiographic parameters were predictive of which side would require treatment first. Patients with FAI requiring surgery should be closely monitored for contralateral hip disease.
