Patients who are suspected to have a posterior cruciate ligament injury should always be evaluated for other knee injuries that often occur in combination with an PCL injuries. These include cartilage/meniscus injuries, bone bruises, ACL tears, fractures, posterolateral injuries and collateral ligament injuries.
There are four different grades of classification in which medical doctors classify a PCL injury:
- Grade I, the PCL has a slight tear.
- Grade II, the PCL ligament is minimally torn and becomes loose.
- Grade III, the PCL is torn completely and the knee can now be categorized as unstable.
- Grade IV, the ligament is damaged along with another ligament housed in the knee (i.e. ACL).
With these grades of PCL injuries, there are different treatments available for such injuries
