Cruciate ligament reconstruction surgery is used to treat a complete rupture of the cruciate ligament. The procedure is usually performed under combined lumbar and rigid anesthesia with a tourniquet at the root of the thigh. Two skin incisions of approximately 1 cm each are made from the anterior aspect of the knee to create an arthroscopic tunnel along the femur near the beginning of the cruciate ligament, and then the reconstructed cruciate ligament material is fixed to the femur on one side through a collar plate, followed by a bone tunnel on the tibia to fix the other side of the reconstructed material to the tibia, thus restoring stability to the knee joint. The postoperative wound is kept dry and the stitches can be removed in two weeks. Postoperative braking with an adjustable knee brace is required for the knee, with different angles adjusted to the different recovery segments. After the reconstruction of the cruciate ligament, care should be taken to avoid strenuous exercise and long distance walking, as this may increase the risk of ligament laxity or rupture.
