Anatomy of Knee

The knee joint has three bones: the thigh, shin, and kneecap. Everything fits snugly. Ligaments and tendons keep everything in place and stable. They stabilize and support the knee. Knee ligaments like the ACL and MCL stabilize the knee. However, quadriceps and patellar tendons connect muscles to bones, allowing us to move and be strong.
