Posterior cruciate ligament is a very important stabilising ligament of the knee joint. It is a very strong ligament and provides stability to the knee joint from behind. Rupture of PCL ligament is quite uncommon in relation to ACL ligament injury and this usually happen in severe injury. PCL can be rupture either in the middle or it can get avulsed from its bony attachment at the tibia. Avulsed bony fragment is fixed with screws and it may be done arthroscopically or open technique. If it is a ruptured in the middle then it requires reconstruction which is done artroscopically.
