Hello,
Arthroscopic surgery or open surgery may be performed for anterior cruciate
ligament injuries. Surgery involves reconstruction of the damaged
ligament using a strip of tendon from the patient's knee (patellar tendon) or hamstring muscle(autografts).In some cases, allograft, xenograft and artificial ligaments may be used. It is followed by an exercise and rehabilitation program to strengthen the muscles and restore full joint mobility
Hope it helps.
