Knee. The posterior cruciate ligament is located in the back of the knee. It is one of several ligaments that connect the femur (thighbone) to the tibia (shinbone). Anatomy Two bones meet to form your knee joint: your femur (upper leg bone) and tibia (lower leg bone). Your patella (kneecap) sits in front of the joint. Bones are connected to other bones by ligaments. There are four primary ligaments in your knee: medial collateral ligament, anterior cruciate ligament, lateral collateral ligament and posterior cruciate ligament (PCL). They act like strong ropes to hold the bones together and keep your knee stable. Cruciate ligaments are found inside your knee joint. By crossing each other they form an âXâ with the anterior cruciate ligament in front and the PCL in back. The cruciate ligaments control the back and forth motion of your knee.
