Anterior cruciate ligament (ACL) injuries are becoming more frequent due to an increase in sports participation. While ACL reconstruction is the gold standard treatment, there is a high risk of graft failure, especially in younger athletes, with around half not returning to their preinjury levels of sports participation. Lateral extra-articular tenodesis (LEAT) can be added to ACL reconstruction to reduce the risk of retears and improve the control of knee rotational stability. LEAT helps control internal tibial rotation and reduces the stress on the ACL graft without increasing the long-term risk of osteoarthritis. Adding a LEAT is especially recommended for high-risk patients, such as young athletes or those with severe rotational instability. With the proper technique, LEAT helps prevent complications, making it a useful addition to ACL reconstruction procedures.

摘要

Anterior cruciate ligament (ACL) injuries are becoming more frequent due to an increase in sports participation. While ACL reconstruction is the gold standard treatment, there is a high risk of graft failure, especially in younger athletes, with around half not returning to their preinjury levels of sports participation. Lateral extra-articular tenodesis (LEAT) can be added to ACL reconstruction to reduce the risk of retears and improve the control of knee rotational stability. LEAT helps control internal tibial rotation and reduces the stress on the ACL graft without increasing the long-term risk of osteoarthritis. Adding a LEAT is especially recommended for high-risk patients, such as young athletes or those with severe rotational instability. With the proper technique, LEAT helps prevent complications, making it a useful addition to ACL reconstruction procedures.
