Bone Contusion and Associated Meniscal and Medial Collateral Ligament Injury in Patients with Anterior Cruciate Ligament Rupture

Abstract

Bone contusions were prevalent in patients with ACL ruptures, and injuries of the menisci and the MCL tended to increase with the progression of bone contusion. The contrecoup mechanism of bone contusion on the medial compartment resulting from an ACL injury was supported. These results suggest that a higher-energy injury led to a more extensive bone contusion and a greater prevalence of associated injury of other anatomic structures in the knee.
