Assessment of Knee Ligament Injuries
When there is suspicion for a multi-ligament knee injury, four main ligament areas of the knee must be assessed for possible injury. Within these areas, there can be several bundles or structures that need to be reconstructed.
The four main ligament areas of the knee that need assessment include: anterior cruciate ligament (ACL),posterior cruciate ligament (PCL), posterolateral knee and medial knee (MCL). Although most complex knee injuries are thought to occur due to a knee dislocation, in actuality, a complete knee dislocation is very rare. Thus, an evaluation of a knee injury that , which involves at least two ligaments being torn, is considered a complex knee injury. Almost all complex knee injuries involve either the anterior cruciate ligament (ACL) and/or posterior cruciate ligament (PCL). Combined with this may be a knee ligament injury involving the medial knee structures (commonly called the MCL). In addition, the posterolateral corner structures of the knee must be completely evaluated.
