The knee joint is reinforced by what?

The knee joint is reinforced by several structures, including ligaments, tendons, and muscles. Key ligaments include the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL), which stabilize the joint by connecting the femur to the tibia. The medial and lateral collateral ligaments provide additional lateral stability, while the surrounding muscles, such as the quadriceps and hamstrings, help support and control movement at the knee. Additionally, the joint capsule and menisci contribute to its overall stability and function.
