What is a Knee Dislocation?
Diagnosis Code: S83.1
A knee dislocation is a serious injury that occurs when the bones of the knee joint, the femur (thighbone) and tibia (shinbone), are forced out of their normal alignment. This often involves damage to multiple ligaments and other supporting structures in the knee, leading to significant pain, instability, and potential complications.
How Does it Occur?
Knee dislocations typically result from high-impact trauma or extreme forces applied to the knee joint. Common causes include:
- Car Accidents: The forces involved in a motor vehicle collision can easily cause knee dislocation.
- Falls: Falling from a significant height or with significant force can dislocate the knee.
- Sports Injuries: While less common, high-impact collisions or twisting injuries in contact sports can also lead to dislocation.
Treatment
- Reduction: The first step in treating a knee dislocation is to realign the bones of the knee joint, a procedure called reduction. This is usually done in an emergency setting.
- Immobilization: After reduction, the knee is immobilized with a brace or splint to allow the initial healing of the injured tissues.
- Surgery: Depending on the extent of damage to ligaments, tendons, and other structures, surgery may be necessary to repair or reconstruct these tissues.
- Rehabilitation: Physical therapy is crucial to regain strength, range of motion, and stability in the knee following a dislocation.
