Knee joint wear simulator

The multi degree of freedom motion characteristics of the knee joint make effective and rigorous in vivo simulation experiments quite difficult. Simulation Solutions Ltd Prosim, together with Biomet, designed and developed independent loading systems for each stationKnee joint wear simulatorFully endow each workstation with load and displacement control, enabling each station to operate independently.

thisKnee joint wear simulatorThe main job responsibilities include:

Compliant with the requirements of ISO14243-1 (2009), ISO14243-3 (2014), and ASTM F3141-17

■Exceeding the loading environment requirements of existing ISO standards for poor wear testing

■Each station is independently controlled and can run specific waveforms according to specific action requirements

■Can simulate and replicate deep knee bending movements

■Integrated spring device simulates soft tissue

■All PROSIM knee joint wear simulators (independent stations) are mechanically and electronically driven, effectively combining motor drivers and gearboxes so that the simulator can closely follow any complex waveform movements

■The simulator (independent station) adopts a multi station configuration to provide reliable and reproducible fatigue simulation tests for knee joint implants, providing accurate and cost-effective testing methods for designers and manufacturers of knee joint artificial implants, and obtaining wear and friction data under realistic in vivo simulation conditions

In the past decade, the empirical data generated by our simulator supports the following statement: the wear shape of knee implants tested in the PROSIM knee implant wear simulator accurately reflects the wear degree of implants that have been used by humans for many years.
