there are a few different types of surgical procedures to stabilize the patella.
--Reconstruction: A graft can be used to stability the patella by strengthening damages ligaments in the knee. The graft can be from a patient or a cadaver. It is typically held in place by screws.
-- Patellar realignment: If the patella is sitting too high in the patellar groove, the groove can be deepened surgically to allow the patella to sit properly in the joint.
--Arthroscopy: Through a small incision in the knee, damaged pieces of the patella are removed, along with some of the cartilate on the back side of the patella that is causing poor alignment with the joint socket.
-- Lateral Release: This is an arthroscopic procedure (done with instruments inserted through small incisions) in which the lateral ligaments of the knee are released to allow the patella to sit in the groove properly.
