Knee Wear Testing
Knee Wear testing is being performed using two Six-station servo-hydraulic Knee simulators. These Knee Simulators provide the most advanced, reliable and accurate methods in evaluating the wear between the femoral component and the tibial insert associated with Knee implants. Our AMTI knee simulators are designed to replicate daily activities such as walking, climbing stairs, running etc allowing us to carry out accurate in-vitro wear testing for clients.
Come see us on booth 5455
The Six Station AMTI Knee Wear Simulator allows us to test up to six implants simultaneously with an additional 4 Load soaked control stations. Our equipment allows us to carry out testing with force or displacement controlled kinematics as per ISO 14243-1 (load control) or ISO 14243-3 (displacement control).
- AMTI simulators can be operated under both force and displacement control
- Each Station has a Six multi-axis load cells
- The six-component force sensors allow for the continuous or periodic measurement of the forces and moments of the x, y, and z axes.
Our highly advanced testing equipment and laboratory allows us to perform ISO and ASTM Standardized testing. Not only can we carry out standardized wear testing but with the aid of our house machine shop we can design and manufacture specialized fixtures to modify set up conditions depending on the client’s needs giving us the ability to provide high quality testing with a prompt and efficient service.
