Hrsk Hinged Rotating Total Knee System for Complex Revision Tka

Three-dimensional (3D) printing, also known as 'Additive Manufacturing' (AM), of titanium orthopaedic implants has revolutionized the treatment of massive bone defects in the pelvis. Their ability to be customized with complex shapes, sizes, and surface geometries offers a significant advantage over conventional manufacturing methods like drop forging and machining.

In terms of manufacturing, 3D printing enables the production of complex porous structures with specifically designed pore shapes, providing control over the final architecture of the porous backside coating that traditional technologies cannot match.

• Optimized pulley groove for enhanced movement.
• Patella trajectory design similar to primary knee arthroplasty.
• Modular hinge mechanism for versatile application.
• Buffered stress conduction significantly reducing bone cement interface loosening.
• Hinge structure prevents direct metal-on-metal contact, minimizing wear.
• Advanced hinge axis allowing up to 120° flexion and 20° inward/outward rotation.
