What is Multi-Ligament Knee Injury?
A multi-ligament knee injury is a complex injury that involves two or more of the following – anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL), and lateral collateral ligament (LCL) / posterolateral corner. These are inherently unstable injuries and can occur with a knee dislocation. Most, if not all, of these injuries will need surgery to restore stability to the knee joint. Dr. Jervis Yau, Santa Barbara, Goleta, Santa Maria and Ventura, California area orthopedic knee surgeon, specializes in multi-ligament knee surgery in order to restore function to a severely damaged knee.
What Causes a Multi-Ligament Injury?
High-energy trauma is the most common cause of multi-ligament knee injury. Patients are strongly encouraged to visit a local ER if there is severe pain, instability and swelling after a high-energy injury. Sometimes, these complex injuries can cause damage to the surrounding nerves and blood vessels, which can be devastating if not diagnosed. A thorough medical review and physical examination, along various diagnostic tests will help determine the severity of the injury.
What is Multi-Ligament Knee Surgery?
The overall goal of multi-ligament knee surgery is to restore stability and function to the knee joint. Dr. Yau strives to perform this procedure in one operation, but there are circumstances where staged procedures must be performed.
Depending on the extent of injury, the torn ligaments can be repaired or reconstructed. With ligament reconstructions, Dr. Yau will remove the damaged tissue and replace it with a new tendon graft. The graft comes in the form of donor tissue (allograft) or native tissue (autograft). Dr. Yau will determine the best graft choice depending on various factors. In many cases, more than one graft may be required to restore stability to a multi-ligament knee injury.
