Complex Knee Ligament Injuries

Multidirectional instability in the knee is seen in a knee that is extremely unstable. Typically, multidirectional instability is due to ligaments of the knee being injured from a knee dislocation, it can also occur in patients with significant joint laxity, such as those with Ehlers-Danlos syndrome.

The treatment of multidirectional instability can be very complicated. The first step in deciding a treatment method for knee instability is to determine the patient’s symptoms. A detailed history is needed to determine if the injury is acute or chronic, and a complex evaluation is required to determine the specific ligaments of the knee that are injured and to also evaluate a patient’s alignment and tibial slope, especially in patients with chronic injuries.

If operative treatment is decided, an experienced surgeon with an experienced surgical team should perform the surgery. In cases of non-operative treatment knee bracing is a viable option.
