The posterior cruciate ligament is one of the knee's main ligaments. It connects to the posterior tibia, and it also connects to the medial condyle. It helps to provide the knee's stability.
If the posterior cruciate ligament is torn, the knee will experience pain, swelling and instability. Other symptoms may also include: knee tenderness, kneeling pain, squatting pain, walking difficulty. In many situations, other knee structures may also be damaged, the knee may have other complications.
Sports or accidents often cause cruciate ligament injuries. Football, basketball or other contact sports tend to tear the posterior cruciate ligament. Vehicle accidents or accidental falls may also cause similar injuries.
