Incidence of Subsequent Injury to Either Knee within 5 Years after Anterior Cruciate Ligament Reconstruction with Patellar Tendon Autograft

Abstract

Women have a higher incidence of anterior cruciate ligament injury to the contralateral knee than men after reconstruction. The incidence of injury to either knee after reconstruction is associated with younger age and higher activity level, but returning to full activities before 6 months postoperatively does not increase the risk of subsequent injury.
