The knee joint is the largest joint in your body. It connects your thigh bone to the bones in your lower leg and also includes the kneecap. The bones in your knees are joined together by ligaments that help provide stability as you walk and move.
These ligaments include:
- Anterior cruciate ligament (ACL)
- Posterior cruciate ligament (PCL)
- Medial collateral ligament (MCL)
- Lateral collateral ligament
