Brief summary
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.
Detailed description
The study is prospective, multi-centric, observational, non-comparative, non-randomized and post market. About 264 subjects will be enrolled in this study to evaluate the safety and performance of the HARMONY® Evolution implants. Patients will be included in the study during 12 months and followed-up during 10 years.
Interventions
It is planned to include consecutive eligible subjects which will be treated with the HARMONY EVOLUTION devices.

| Evaluate performance by means of clinical and quality of life scores | 2 months, 1, 3, 5 and 10 years follow-up | Score PMA \> 15 points |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Evaluate performance by means of surgeon satisfaction questionnaire | 2 months, 1, 3, 5 and 10 years follow-up | Evaluate the success of the surgical procedure and evaluate surgeon satisfaction regarding the implant components and the use of instruments with the criteria: very satisfied - satisfied - unsatisfied - very unsatisfied for each surgical step. |
