The lateral collateral ligament connects the fibula to the femur. This ligament is part of a complex of ligaments called the posterolateral ligament complex. This complex is made up of the lateral collateral ligament, the menisco-fibular ligament and the popliteus tendon. When the ligament is torn some common symptoms include pain and sensitivity in the area of the knee as well as swelling of the knee. Some patients experience instability when placing their body weight onto the knee.

If Dr Marais suspects that the lateral collateral ligament is injured, he may examine the knee in order to determine the extent of the damage and they will perform an imaging test such as X-rays and MRI scan. These test will help him to confirm his diagnosis.

Injuries of the lateral collateral ligament can not be treated in a brace alone and needs to be repaired surgically.

After surgery Dr Marais will advise you on the best rehabilitation plan which may include physical therapy and some lifestyle changes. You will wear a brace for a minimum of six weeks after the repair.
