Patellar Instability

What is it and how is it treated?

What is Patellar Instability?

The patella (kneecap) attaches to the femur (thigh bone) and tibia (shin bone) via the quadriceps and patellar tendon.  It sits in the trochlear groove in the knee and slides up and down as the knee bends and straightens. Patella instability is most often seen in children and occurs when the patella does not stay within the groove in the knee and seems to slide in and out of position.

There are two main types of patellar instability:

Traumatic Patellar Dislocation.  The kneecap is forcefully pushed completely outside the groove due to a direct blow to the knee.  This causes the patella to no longer stay within the groove of the knee, especially during activity.

Chronic Patellar Instability. The kneecap “slides” partially in and out of the groove during activity.

If your child has patellar instability the symptoms can include:

  • Knee pain
  • Swelling 
  • Stiffness
  • A feeling of the knee “buckling”
  • A feeling of “catching” or “locking” in the knee
  • Visible deformity in the knee

The Board Certified Orthopedic and Sports Medicine Specialists at OrthoNeuro have helped thousands of patients with patellar instability return to an active and healthy lifestyle using a variety of treatment options.

How is Patellar Instability Treated at OrthoNeuro?

Depending upon the category of patellar instability and the severity of the condition, there are several treatment options.  In many cases, your OrthoNeuro Specialist recommends conservative treatment options for patellar instability after the patella is manually returned to the correct position within the knee.

These treatment options can include:

  • Bracing
  • Immobilization
  • Physical Therapy

In some cases, the cartilage within the knee may be damaged and therefore an arthroscopic surgical procedure may be recommended to remove the damaged cartilage.

If your child continues to have chronic patellar dislocations after conservative treatment, an arthroscopic procedure (known as an osteotomy) may be recommended.  During this procedure, the groove within the knee is reshaped so that the kneecap can sit in its correct position.

The Board Certified Orthopedic Surgeons at OrthoNeuro are experts in these procedures and have helped thousands of patients return to an active and healthy lifestyle following these procedures.
