Normal appearance and complications of double-bundle and selective-bundle anterior cruciate ligament reconstructions using optimal MRI techniques.

Abstract

Double-bundle and selective-bundle anterior cruciate ligament (ACL) reconstructions are increasingly performed to better reproduce the double-bundle anatomy of the native ACL and to improve knee stability and surgical outcomes. This article illustrates how to optimize visualization of the ACL bundle anatomy and the appearances of graft components and postoperative complications. It is important for the radiologist to be familiar with the appearance of double-bundle and selective-bundle ACL reconstructions and associated complications.
