Post-Market Observational Study of the HARMONY® Evolution Implants and Instruments

The purpose of this study is to evaluate the safety and performance of the HARMONY® Evolution implants in a series of operated subjects treated in THR. The objective is to demonstrate that the evaluated implants are compliant with the state of the art and the performance (PMA score \> 15 points) \& safety claims (The expected acceptable revision rate (state of the art with a confidence interval of 95%) is 3% at 3 years, 5% at 5 years, 7% at 7 years and 10% at 10 years). The endpoint of this study is to validate the expected performance of the HARMONY® Evolution implants with the PMA score at 10 years and to validate the safety claim with the expected acceptable revision rate at 10 years.
