Knee Dislocation

What is Knee Dislocation?

Knee dislocation is a condition that occurs when the bones that form the knee joint, namely the femur or thigh bone get separated from the shin bone. This can cause serious damage to the nerves, blood vessels, and ligaments surrounding the knee, leading to a decline in strength and overall health of the leg.

Causes of Knee Dislocation

Dislocation of the knee is rare. When it does occur, it is usually caused due to high impact injuries from automobile accidents, severe falls, or sports.

Symptoms of Knee Dislocation

The dislocation of the knee can occur quickly. You may hear a popping sound at the time of the injury. Other symptoms can include:

  • Severe pain
  • Visible deformity at the knee joint
  • Swelling
  • Instability of the knee joint
  • Limitations in the movement of the knee

Diagnosis of Knee Dislocation

Your doctor will review your symptoms and medical history and perform a thorough physical examination to check for a range of motion and any damage to the ligaments, blood flow, stability, and skin color. The following diagnostic tests may be performed for further evaluation of the injured knee.

  • X-rays: During this study, high electromagnetic energy beams are used to produce images of the bones
  • CT scan: Special x-rays are used to produce images of any damage in the knee

Treatment for Knee Dislocation

You will be instructed to apply an ice pack and keep your knee in an elevated position to reduce swelling. Depending on your condition, your doctor will place the affected leg in a therapeutic brace to keep it stable and may prescribe medications to reduce pain and swelling. You may need surgery to repair any damaged ligaments, blood vessels, nerves, or any adjacent structures of the knee
