A dislocation of the knee is a serious injury where most or all of the ligaments of the knee become disrupted and the thighbone (femur) dislocates from the shinbone (tibia).


Not the same as dislocated kneecap

Dislocation of the knee is a rare condition, and quite different from dislocation of the kneecap. Blood vessels and nerves are at extreme risk and it is generally considered extremely important to order an angiogram as early as possible after reduction to check the arterial supply. Soft tissue damage, eg ligaments, are likely to require surgery once the situation is stable.
