Reconstruction of lateral collateral knee ligament

A strong synthetic ligament and a knot-free technique ligament

Injuries to the lateral collateral ligament are rare but result in varus joint instability that requires correction. It may or may not be associated with another ligament injury, and a complete evaluation of the other ligaments of the knee is crucial when planning corrective surgery.

There are two anatomical and functional features to consider. The first is the distal insertion of the lateral collateral ligament, which is located on the fibular head. Ligament repair must be as close as possible to this location for optimal isometry. The second is the fact that the lateral collateral ligament only tightens in extension and is loose in flexion, thus participating in a certain degree of internal rotation, usually counteracted by the cranial cruciate ligament.
