What do the anterior cruciate and posterior cruciate ligaments do?

Stability: Together, they function to keep your knee in place. They keep the knee from moving too far front and back as we'll as rotating too far. The acl prevents forward shifting and rotating while the PCL prevents backward shifting and outward rotating. Tears of the acl do not heal and often end up with acl reconstructions.

Please explain what happens with a posterior cruciate ligament tear?

Please explain what happens with a posterior cruciate ligament tear?

Instability: The posterior cruciate ligament (pcl) is the ligament that keeps the tibia (shin bone) in line with the femur (thigh bone), and keeps it from dropping back behind. When it tears, the body tries to heal the tear but in a looser position. Sometimes this is loose enough to cause instability (where the knee sags back and is unable to maintain a normal position. This can cause other tears or disability. ...Read more
