An injury to the posterior cruciate ligament, one of the four major ligaments of the knee joint, is known as a PCL (Posterior Cruciate Ligament) injury. The PCL, which is situated at the rear of the knee, serves to stabilise the joint by limiting the shin bone’s (tibia) movement in proportion to the thigh bone’s (femur) backwards motion.
The severity of PCL injuries may vary from minor sprains to full rips. They often originate from trauma or direct contact to the front of the knee, as in a vehicle accident or collision during a sporting event. Falls, automobile collisions, or sports involving abrupt pauses or direction changes are a few typical reasons.
Depending on how severe the damage is, a PCL injury may cause a variety of symptoms. Pain, swelling, instability, trouble walking or bearing weight on the afflicted leg, and a sensation of the knee “giving way” or buckling are a few of the usual indications and symptoms.
