Knee Dislocation

Knee is the joint that connects the two bones of the lower leg, fibula and tibia, to the upper thigh bone, femur. Another bone called the patella or the knee cap lies in front of the joint. All the bones are held together by the ligaments that not only support the joint but also enable the bones to move in perfect alignment with each other. Knee dislocation is a condition that refers to a situation where in one or more of these bones move out of their anatomical position and thus disrupt the joint movement. This generally happens when the supporting ligaments are either stretched or become loose or they are torn.

Dislocation may be complete with tearing of ligaments and complete displacement of the bones or it may be partial (also called subluxation) when the ligaments may be stretched beyond their capacity and the bone may be slightly displaced. It most commonly occurs in the anterior or posterior directions. Knee Dislocation requires immediate medical attention as delays may cause permanent joint disability. It is considered to be a serious type of injury and the knee joint may not be able to return to its original shape and functional capacity even post-treatment.

Causes Of Knee Dislocation

  • Vehicular crash or accidents
  • A direct fall on the knee
  • Direct trauma incurred in high speed sports/activities or physical combats

Symptoms Of Knee Dislocation

  • Visible deformity in the leg and the knee
  • Swelling and redness which may be a result of fluid accumulation within the joint
  • The joint may be tender to touch
  • Pain which can vary from mild ache to a severe pain
  • There may be no sensation in the knee and leg
  • Slight physical movement and weight bearing can be painful
  • Foot numbness

Diagnosis Of Knee Dislocation

  • Clinical examination of the injured knee by checking for visible symptoms, loss of movement or sensation and pulses
  • An X-ray may be conducted to assess the damage to the bone structure or the degree of dislocation
  • Arteriogram- An X-ray conducted to check for artery damage
  • Ultrasound may be required
  • Neurological tests may be needed to check for nerve damage and loss of sensation in the muscles

Treatment For Knee Dislocation

  • The patient may apply ice to the injured leg immediately after the injury to bring down pain and swelling
  • The leg should be elevated at chest level and given adequate rest
  • The lower leg bones may be manually reduced or brought back in their original place by manipulating them with hand
  • Pain killers and anti-inflammatory medicines may be administered to provide relief to the patient
  • In case of arterial damage or loss of nerve function, surgical intervention may be required to prevent the loss of leg function. It is done to restore normal blood supply to the joint and lower extremities
  • A splint, brace or a cast may be used to immobilize the joint and help the bones settle back in their anatomical position
  • Crutches may be used to prevent weight bearing
  • In case of bone and ligament breaks, surgery is generally required to reconstruct the damaged parts
  • Post-operative care and a proper rehabilitation program designed by the experts need to be followed for a couple of months to restore strength and flexibility of the knee
  • Stressful sports activities and exercises need to be avoided post-surgery
