This life-size functional model of the human knee stands 12 inches tall and features movable components that demonstrate the range of motion of the knee joint. The model highlights the anterior and posterior cruciate ligaments as well as the medial and lateral collateral ligaments that support the femur, fibula, and tibia. A key card with 10 callouts is included for identification of anatomical structures. This model is suitable for anatomy courses, physical therapy education, and medical training where hands-on examination of knee joint mechanics is beneficial.
