Patellar Dislocation – Frisco, TX
The patella (or the kneecap) is one of the main bones that form the knee joint. In some cases, this knee cap bone tends to slip out of the patellofemoral cavity where it is placed and causes a lot of discomfort and physical limitations. In normal conditions, the patella moves up and down within this femoral cavity whenever the knee is bent or moved. It is connected to the quadriceps muscles that help keep it in place. If the patella is partially displaced, the condition is called subluxation and it is moves out of the femoral groove completely, the condition is referred to as Patellar Dislocation. This type of injury is most common in young athletes although others may also be affected.

Causes Of Patellar Dislocation

  • Direct hit or blow inflicted on the leg or the knee
  • Sudden twisting or turning of the knee
  • Congenital deformities may make a person susceptible to such dislocations
  • Biomechanical fault in the joint alignment
  • Use of improper shoes that do not give support to the feet and knee may be a potential cause
  • Overuse injuries especially in athletes and women
  • Past joint injuries
  • Weight lifting
  • Running excessively and changing directions suddenly like football or soccer players

Symptoms Of Patellar Dislocation

  • Pain which may set in immediately post injury
  • Locking or catching of the knee may be reported in case there is a loose body present within the joint spaces
  • Limited range of motion remains and it is difficult to climb the stairs, play a sport, cycle, bend or squat
  • Swelling and tenderness
  • A visibly dislocated kneecap

Diagnosis Of Patellar Dislocation

  • Thorough clinical examination of the injured leg and analysis of the patient’s medical history
  • The doctor may palpate the knee to check for the location of damage, exact location of pain and the level of dislocation
  • X-ray imaging
  • MRI scan

Treatment For Patellar Dislocation

  • Painkillers and anti-inflammatory medicines may be prescribed for relief
  • All activities that stress the kneecap must be avoided
  • Rest the affected knee by keeping the leg elevated at chest level
  • Compression may be applied by using a soft bandage
  • Cryotherapy- ice packs may be applied at regular intervals for the first 2-3 days of injury. It prevents swelling
  • A cast or a knee brace may be used for about 2-3 weeks to immobilize the joint
  • Exercises for strengthening of the hamstring and quadriceps muscles may be initiated under a specifically designed physical therapy program
  • Use of orthotic devices that can be inserted in the shoes may be used
  • A special tape may be used to improve the knee alignment and keep it stable
