The arthroscope is reinserted into the knee joint through one of the small incisions.

The torn ACL will be removed and the pathway for the new ACL is prepared. A small incision is made over the hamstring tendon attachment to the tibia and the two tendons are stripped off the muscle and the graft is prepared. The knee is bent at right angles and the hamstring tendons felt. Along with the arthroscope, a sterile solution is pumped into the joint to expand it enabling the surgeon to have a clear view and space to work inside the joint. An arthroscope, a tube with a small video camera on the end is inserted through one incision to see the inside of the knee joint. Your surgeon will make two small cuts about 1/4 inch long around your knee. The procedure is performed under general anesthesia. The Hamstring is the muscle located on the back of your thigh. The goal of ACL reconstruction surgery is to tighten your knee and to restore its stability.Īnterior cruciate ligament reconstruction hamstring method is a surgical procedure to replace the torn ACL with part of the hamstring tendon taken from the patient’s leg. During this test, if the ACL is torn, the tibia will move forward when the knee is completely straight and as the knee bends past 30° the tibia shifts back into correct place in relation to the femur. Pivot shift test is another test to assess ACL tear. During a Lachman test, knees with a torn ACL may show increased forward movement of the tibia and a soft or mushy endpoint compared to a healthy knee. In addition, your doctor will often perform the Lachman’s test to see if the ACL is intact. X-rays may be needed to rule out any fractures. DiagnosisĪn ACL injury can be diagnosed with a thorough physical examination of the knee and diagnostic tests such as X-rays, MRI scans and arthroscopy. You may notice that the knee feels unstable or seems to give way, especially when trying to change direction on the knee.

Within a few hours after an ACL injury, your knee may swell due to bleeding from vessels within the torn ligament. When you injure your ACL, you might hear a loud "pop" sound and you may feel the knee buckle. Direct blow to the side of your knee, such as during a football tackle.CausesĪn ACL injury most commonly occurs during sports that involve twisting or overextending your knee.
Anterior cruciate ligament reconstruction is surgery to reconstruct the torn ligament of your knee with a tissue graft. Anterior cruciate ligament prevents excessive forward movement of the lower leg bone (the tibia) in relation to the thigh bone (the femur) as well as limits rotational movements of the knee.Ī tear of this ligament can make you feel as though your knees will not allow you to move or even hold you up. Anterior cruciate ligament is one of the four major ligaments of the knee that connects the femur (thigh bone) to the tibia (shin bone) and helps stabilize your knee joint. ACL Reconstruction Hamstring TendonĪnterior cruciate ligament (ACL) reconstruction hamstring method is a surgical procedure that replaces the injured ACL with a hamstring tendon. When this ligament tears unfortunately, it does not heal and often leads to the feeling of instability in the knee.ĪCL reconstruction is a commonly performed surgical procedure and with recent advances in arthroscopic surgery can now be performed with minimal incision and low complication rates. It is a strong rope like structure located in the center of the knee running from the femur to the tibia. The anterior cruciate ligament is one of the major stabilizing ligaments in the knee.
