A sprain occurs when the structures that stabilize the joints and restrict extreme movements are stretched.

The knee has internal and external collateral ligaments as well as cross ligaments that restrict knee extension and the external rotation of the tibia (leg bone). These ligaments also provide lateral stability to the knee (i.e., prevent movements to the side). A number of traumas can cause injury to these ligaments - anything from a simple pulled muscle (1st degree sprain) to a complete tear (3rd degree sprain). Combined injuries to both knee ligaments and menisci are not unusual, although an isolated single ligament rupture may also occur. Most sprains are caused by a lateral impact to the knee or excessive torsion of the joint. It is important to get the injury assessed by a physiotherapist as soon as possible, as quick treatment promotes a speedier and longer-lasting recovery. Don't hesitate to contact us!
