About the Procedure
Patellar instability is a condition where the Patella (kneecap bone) dislocates completely or partially out of its joint. Most acute patellar dislocations occur because of a non-contact twisting injury to the knee, or a direct blow to the inside of the knee.
If the patella dislocates for the first time, treatment is usually conservative. However, this can increase the risk of continuous symptoms including recurrent dislocations. Recurrent kneecap dislocations are as high as 44% after conservative treatment and can increase the risk of patellar osteoarthritis. A single previous dislocation is associated with the highest risk of persistent patellar instability later in life.
In patellar dislocations, the medial patellofemoral ligament (MPFL) is often damaged. Ligament reconstruction involves removing the damaged ligament and replacing it with a tissue graft. In terms of graft choice, a hamstring graft from the patient’s knee or a donor tendon (allograft) can be used.
