Prevalence and Incidence of Cartilage Injuries and Meniscus Tears in Patients Who Underwent Both Primary and Revision Anterior Cruciate Ligament Reconstructions

Abstract

In this community-based sample followed from primary ACLR to revision ACLR, the prevalence of articular cartilage injuries increased, while the prevalence of meniscus injuries decreased. The higher prevalence of articular cartilage injuries at revision ACLR may represent new injuries. The lower prevalence of meniscus tears at revision ACLR may be caused by susceptible menisci being injured and treated at primary surgery or by changes in knee kinematics or injury exposure patterns.
