Ligament injuries in the knee are commonly seen in two areas: the first is the anterior cruciate ligament (ACL) injury, and the second is the medial collateral ligament (MCL) injury. The treatment for these two ligament injuries is the same; for instance, in cases of just a simple ligament tear or partial tear, it only requires the use of a plaster cast for external fixation, and immobilization for three to four weeks can achieve recovery.

If there is a complete tear, surgery might be needed. There are two types of surgeries: the first one involves direct repair of the ligament, the second involves using autologous tendons to reconstruct the ligament, restoring the stability of the entire knee joint. To determine whether you have a tear, complete tear, or partial tear, it is necessary to undergo an MRI of the knee to confirm.
