In the sporting world, anterior cruciate ligament injuries occur more frequently. A torn anterior cruciate ligament from a major knee injury is a typical outcome. The ACL is the knee joint’s main stabilizer. The muscles of the thigh and calf are secondary stabilizers of the joints of the knee. You usually have a rapid spinning movement with your leg fixed on the ground if you’ve broken your ACL. It is possible to hear a crack or pop and the knee normally swells up within a few hours. The ligament either breaks in half or is torn from the surfaces of the femoral or tibial. The ligament cannot heal itself completely broken. Partial tears may heal, but tendons are also stretched to make room for the knee. In certain movements, the anterior cruciate ligament rupture will cause the knee to become unstable. This normally happens when one pivot, like a sudden shift of direction. It looks like the knee is going to give way.
