Fatigue Testing of TKR Femoral Components Under Closing Conditions
Fatigue testing applied to the medial condyle of a femoral TKR component in an inverted position to simulate single condyle loading at 90° knee flexion. The femoral component is potted to a defined depth which leaves the regions of highest stress exposed to the test. Cyclic loading is applied until run-out is achieved or device failure. This standard is still in development.
