There are two major ligaments in the knee joint: the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL). By far, the ACL is injured or damaged more often than the PCL. Not as much is known about what happens when the PCL is torn. A recent study in Germany tracked 181 patients with PCL tears who did not have surgery to repair the injury. They found that damage to the joint cartilage after a PCL tear is common. In fact, more than half of all patients with a PCL tear develop cartilage damage and arthritis after that.After a PCL tear, there is a change in where the knee joint comes together during movement. A weak PCL causes more pressure on the inside edge of the knee. Higher loads and greater force act on the cartilage. The cartilage gets worn down and damaged.

The answer to your question may depend on what you mean by “pretty loose.” Joint laxity in the knee can be graded from one to three with a test called the drawer test. An anterior drawer test measures laxity of the anterior cruciate ligament (ACL). A posterior drawer test grades the posterior cruciate ligament (PCL).

Studies show the PCL doesn’t return to “normal” after surgery. The goal of the operation is to improve joint laxity. PCL repair usually reduces laxity by a full grade or more. Even with the best results there’s often a trace amount of laxity.

Even though your joint may be loose, the real measure of success is to compare the laxity before and after the operation. Talk to your surgeon if there doesn’t seem to be any difference. Ask if your knee is stable enough to return to normal sports and activities.

There are two major ligaments that criss-cross inside the knee joint to give it stability. One is the anterior cruciate ligament (ACL) and the other is the posterior cruciate ligament (PCL).

ACL tears don’t regenerate tissue and heal on their own. In minor ACL injuries surgery may not be needed. Instead knee rehab is used to regain motion and strengthen the muscles around the knee. More serious injuries may need surgery to repair or reconstruct the torn ligament.

Unlike the ACL, the PCL does have the ability to heal. This has been shown with MRI studies. Healing does depend on how severe the injury is–more severe injuries may need surgery to improve laxity.

Without surgery it’s not clear yet how long the healing process takes. The PCL doesn’t return to normal but motion, strength, and control are regained.

  The cruciate ligaments are two ligaments that cross inside the knee joint. (“Cruciate” means cross). By connecting the thighbone (femur) with the shinbone (tibia), they help stabilize the knee. The ACL is in front. It protects the tibia from going too far forward in relation to the femur. The PCL crosses behind the ACL. It’s made up of two bands that work together to stabilize the knee when the lower leg is moving backward or rotating outward.

You hear more about the ACL because ACL injuries are more common. They also tend to result in more pain and symptoms than PCL injuries. However, recent studies suggest that PCL injuries may be more common than previously thought, accounting for roughly 20 percent of all knee injuries. Researchers have recently turned more of their attention to PCL injuries, to develop more effective treatments.
