dislocation of knee

Displacement of the knee (tibiofemoral joint), an uncommon injury, universally complicated by tearing of the cruciate ligaments, and often associated with peroneal nerve or popliteal artery damage. In a knee dislocation at least three of the four major ligaments, anterior cruciate, posterior cruciate, medical collateral, lateral collateral, are torn. Dislocations should be reduced by an orthopedic surgeon as soon as is feasible to preserve circulation to the lower extremity.
