Loading and displacement waveforms, which simulate the patellofemoral kinetics and kinematics by combining a squatting sub-cycle with two walking gait sub-cycles, are performed until delamination, cracking, or another identified failure mode occurs. If the implants do not demonstrate any failure modes by 220 thousand cycles, the test is stopped. The EndoLab® knee joint simulator is used for testing.
