How can i treat patellar dislocation?

Reduce it: Obviously the initial treatment for any patella dislocation is to replace the patella into proper position. The leg should then be immobilized to allow healing and to allow swelling to subside. Then one must evaluate the knee and determine if this is a onetime traumatic event or a recurrent problem which might require either physical therapy or a surgical procedure.

Slowly: You need to rest it first. Let the swelling go down. Avoid deep bending during healing. Ice, nsaids, patellar "palumbo brace" to hold the knee cap towards the center, therapy to stregthen the vastus medialis muscle of your quadriceps. Then a slow return to sports. If acute, MRI is used to look for an cartilage injury from the dislocation.
