We have demonstrated a technique to replicate the worst case failure mode of a known implant failure. We believe that the proposed test setup can be used to benchmark various implant designs against known clinically successful UKRs. Ideally, the next step of our proposal would be to test the S&N implant in our model setup to establish an acceptable load, illustrating that the implants could survive the well-established 10 million cycles of fatigue loading. F1800 calls for a load of 900N based on the clinical failure of an implant replicated in a test setting. For an implant that is designed to support approximately 70% of the knee joint load, 630N would be a reasonable starting point.
