The PCL, or posterior cruciate ligament, is similar to the ACL as it helps connect your thigh bone to your shin bone. The most common reason for a PCL tear is high impact to the top part of the shin from car accidents or in contact sports like soccer or football. Typical symptoms of PCL tears are instability, swelling, and pain. After a PCL injury, it’s important to protect your knee joint with a hinged knee brace that will protect the ligaments as you exercise. We carry a variety of PCL injury braces from notable brands, including Donjoy.
