• Stress transmission is buffered, significantly reducing cement-bone interface loosening.

• The hinge structure prevents direct contact between the metal hinge axis and the metal femoral condyle, minimizing wear.

• Designed so that 95% of the load is borne by the tibia, aligning with the load distribution of primary prostheses; gravity and joint surface stress are primarily supported by the tibiofemoral joint surface.

— High compatibility ensures direct contact between the femoral condyle and tibial insert throughout the entire range of flexion and extension, allowing for effective load-bearing.

— The well-matched tibiofemoral joint surface also provides damping constraints at extreme flexion and extension positions: During prosthetic hyperextension, the anterior curvature of the HRSK comes into contact with the tibial joint surface. This interaction slightly separates the knee joint, preventing hyperextension impact.
