Bionix^® Knee Wear Simulator

Accurately replicate a full range of knee forces and motions

Orthopaedic researchers worldwide trust Bionix® Knee Wear Simulators to conduct long-term wear, fatigue and durability tests on implantable knee devices and related materials.

These precise, highly durable simulators accurately replicate the full range of real-world knee forces and motions, enabling you to generate the high-quality wear data required to gain device approval, validate production processes and continue development.

Six test stations facilitate statistically significant sampling and minimize testing time. The compact, modular design includes an advanced hydraulic actuation scheme that delivers precise, closed-loop control of four independent degrees of freedom, while exhibiting dynamic performance and stiffness not possible with other actuation approaches.

Durable, low-friction MTS linear actuators and state-of-the-art servovalve technology generate user-defined flexion/extension, axial force, anterior/posterior and tibial rotation motions. The simulator can also achieve operating speeds up to two cycles per second for accelerated test protocols.
