Anterior Cruciate Ligament (ACL) is one of the four main ligaments in the knee that are critical to the stability of the knee joint. This ligament connects the thigh bone (femur) to the shin bone (tibia), keeping the knee from hyperextending, preventing anterior dislocation at the tibia, providing rotational stability and support to help prevent unnatural movement in the joint. The ACL can be injured if the knee is twisted, bent side to side, or hyperextended.
High-impact activities involving rapid twisting movements like Basketball, football, soccer, baseball, tennis, and skiing may place extreme forces on the knee, which can lead to injury. ACL injuries can also occur in older adults as the ACL becomes weaker with age.
The symptoms which can report you about ACL injury are: knee usually develops acute swelling and pain, and the inability to weight bear is common. Which can make sudden pivoting movements difficult, and an unstable knee may be more prone to developing arthritis and cartilage tears.
It is better to get diagnosed with the problem or to evaluate other ligament and/or cartilage damage. Depend upon the complexity of the problem, the decision whether or not to have surgery will be decided.
