Left knee following hamstring autograft ACL reconstruction, partial meniscectomy and medial meniscus repair. The retear rate in young, active individuals has been shown to be lower when using autograft as compared to allograft. īecause the tissue used in an autograft is the patient's own, the risk of rejection is minimal. While originally less commonly utilized, the quadriceps tendon has become a more popular graft. Īn accessory hamstring or part of the patellar ligament are the most common donor tissues used in autografts. Synthetic tissue for ACL reconstruction has also been developed, but little data exists on its strength and reliability.Bridge-enhanced ACL repair (using a bio-engineered bridging scaffold injected with the patient's own blood).Allografts (using bone or tissue from another body, either a cadaver or a live donor).Autografts (employing bone or tissue harvested from the patient's body).Graft options for ACL reconstruction include: The two bright objects in this X-ray are screws in the thigh bone (above) and shin bone (below). The graft is then pulled through the tunnel and fixated with screws. Grafts are inserted through a tunnel that is drilled through the shin bone (tibia) and thigh bone (femur). An increased Q angle and hormonal differences are a few examples of the gender disparity in ACL tear rates. ACL injuries account for a quarter of all knee injuries in the high school population. ACL injury is 4-6 times higher in females than in males. However, non-contact tears typically occur during the following movements: decelerating, cutting, or landing from a jump. ACL injuries can be categorized into groups- contact and non-contact based on the nature of the injury Contact injuries occur when a person or object come into contact with the knee causing the ligament to tear. Around $500 million health care dollar will come from ACL injuries. 1 in every 3,000 American suffers from a ruptured ACL and between 100,000 and 300,000 reconstruction surgeries will be performed each year in the United States. Anterior Cruciate Ligament Reconstruction (ACL) surgery is a common intervention. Anterior Cruciate Ligament damage is a very common injury, especially among athletes. The Anterior Cruciate Ligament is the ligament that keeps the knee stable. 2.4 Bridge Enhanced ACL Repair (BEAR Implant).
