Kneecap Instability

Kneecap Instability, or Patellar Instability, is a medical condition in which the patella (kneecap) dislocates from its original position. The kneecap is situated in the front part of the knee. When the knee is bent, the patella smoothly glides in a channel of the femur known as ‘trochlear groove’. When the patella moves or slips out of this groove, it leads to instability. The condition can also lead to a partial dislocation of the patella, known as subluxation.

Causes Of Kneecap Instability

  • Severe blow or twisting of the knee
  • Insufficient quadriceps strength on the inside of the knee
  • Over pronation of the feet
  • Increased ‘Q’ angle of the knee
  • Knocked knees
  • Hereditary

Symptoms Of Kneecap Instability

  • Sudden pain at the time of injury
  • Inflammation in the knee joint
  • Displacement of the knee cap
  • A visible lump in the outside part of the leg
  • A feeling of buckling of the knee
  • Clicking sound emanating from the knee

Diagnosis Of Kneecap Instability

An orthopedic doctor may first ask questions pertaining to the sequence of events that led to the injury. A thorough physical examination may be conducted to evaluate muscle weakness and alignment issues. The doctor may also look at the gliding path of the patella in the trochlear groove.

Imaging tests such as X-rays may be conducted to have a clear picture of the patella and trochlear groove. The patient may be asked to undergo an MRI scan to have a closer look at the cartilage lining of the joint. The soft tissues holding the patella in place may also be assessed for damage.

Treatment For Kneecap Instability

  • RICE: RICE therapy refers to rest, ice packs, compression and elevation. It helps to reduce the symptoms like pain and inflammation
  • Taping or bracing: In some instances, the taping of kneecap into place may provide relief from pain. A stabilizing knee brace may also prove to be useful.
  • Surgery: Surgery is required if the instability becomes a recurrent problem. During the procedure, the ligament on the inner part of the patella is reconstructed. Another procedure known as the tibial tubercle osteotomy may be performed in case there are multiple abnormalities in the movement of the patella in the trochlear groove.
  • Rehabilitation: Once the pain and swelling start to subside, the doctor may recommend certain exercises to regain normal range of motion. The rehabilitation program is designed to eliminate swelling and strengthen the quadriceps muscle, particularly the vastus medialis obliquus (VMO) muscle.
