A knee dislocation is a serious and painful condition of knee. In knee dislocation, knee cap slides out of its place. This causes swelling and inflammation in the knee. The activities involving lower extremities of a person enhance the chance of this condition. People in sports such as football, soccer, etc are more prone to knee dislocation.


Women are often seen to have knee dislocation. A variety of causes may result in dislocated knee:

  • Highly-energized traumatic injuries
  • Rapid change in direction of leg
  • Abrupt blow to the kneecap
  • Wrenching of knee


Knee dislocation is usually characterized by severe pain and irritation in the knee. Other symptoms include:

  • Displaced and sloppy kneecap
  • Swelling and tenderness
  • Bent and deformed knee
  • Stiffness
  • Creaking sound in knee movement


A variety of tests and physical examinations are performed to diagnose the actual cause. The tests include x-ray, MRI scan, bending of knee, etc. The doctor carefully examines affected area for deciding the actual treatment procedure. In early stages of knee dislocation, non-surgical treatment method is preferred. In case, non-operative methods fail, then surgery is opted.

The non-surgical treatments include following procedures:

  • Applying cold packs

Mild or moderate pain and swelling can be lowered by placing ice packs on the affected area. It gives a relief from the burning sensation or irritation.

  • Immobilization

  • Surgical Treatments:

In some patients, conservative methods do not provide much help to reduce symptoms. Surgery is opted in such circumstances. Prior to surgery, local anesthesia is given to the patient to numb the affected site.

Surgery may include reduction process or complete knee reconstruction. In reduction surgery, the damaged or torn ligaments, nerves and blood vessels of the knee are repaired. In severe cases, the bones may completely break into pieces. This result in intense pain and sprain in the knee. In such situations, the complete knee is reconstructed. This helps to restore the knee functions and flexibility.


After surgery is over, the knee is kept in braces or crutches to stabilize the knee. Avoid excessive weight on the affected part of knee. Regularly clean the wound to avoid infections. The doctor often prepares a physical therapy program to get back the knee in normal position. A recovery is usually seen within 2-3 months.
