When a multi-ligament knee injury occurs, multiple ligaments are affected simultaneously. These accidents are intense, usually as a result of motor vehicle accidents, sports injuries and sudden falls.

Multi-ligament repair involves reconstructing and rebuilding the affected soft tissues and preventing further problems that may occur with an unstable knee, such as osteoarthritis.

What are the symptoms of multi-ligament injuries?

• Pain or swelling along the affected area
• Restricted/limited mobility of the knee
• Damage to the arteries or nerves of the leg
• Knee instability

How do you diagnose multi-ligament injuries?

Diagnosing multi-ligament injuries involve identifying the torn ligaments and the extent of these injuries. Common imaging tests include an MRI of the affected knee or an X-ray of the knee.

However, before surgical reconstruction of the affected ligaments, Dr Vardi performs an arthroscopic examination for functional testing and to confirm that the ligaments have been damaged.

How do you perform multi-ligament reconstruction?

A general anaesthetic is administered to help put the patient to sleep in preparation for the procedure. Multi-ligament reconstruction is a procedure that can be carried out arthroscopically by making a few small cuts over the knee. The orthopaedic surgeon avulses/retracts the ligaments from the bone during reconstructive surgery. Afterwards, he reconnects the ligaments to the bone using sutures. In order to recreate or rebuild the ligament, Dr Vardi uses a graft from the patient’s body or donor tissue. Next, a drill is used to create a tunnel in the thighbone and tibia. The graft is then placed through the tunnel to replace the ruptured ligaments. Finally, fixation devices are used to hold the grafts in place while the ligament heals.
