Knee Dislocation

Knee Dislocation Overview

A knee dislocation occurs when the bones that form the knee are out of place. A knee dislocation, more specifically, is when the bones of the leg (the tibia and fibula) are moved in relation to the bone in the thigh (femur). The bones of the knee are held together by strong bands of tissue called ligaments. Each ligament is responsible for stabilizing the knee in a certain position. For a knee dislocation to occur, these ligaments must tear. A partial dislocation is referred to as a subluxation. In some injuries, the kneecap (patella) and its ligaments are also disrupted.

Inappropriate or delayed treatment of a knee dislocation may result in loss of the leg.
