Clinical trials

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.

The study objective is to evaluate safety and performance of the ORIGIN® CR (cruciate retaining) devices and associated instruments, more precisely to evaluate safety by the proportion of patients requiring a revision (i.e. revision rate) at 1-year post procedure and to evaluate performance by means of a Knee Society Score (KSS) Knee Score at 1 year post procedure and by means of a KSS Function Score also at 1 year post procedure. The hypothesis raised for this study, regarding the scoring, is that patients will experience a marked improvement in the natural feel of the prosthesis during the first year after the surgery, and slightly significant improvement at the following interval of 2 years. The overall patient satisfaction is expected to be improved after 2 years follow-up with ORIGIN® CR.

The study objective is to assess patient satisfaction after the surgery with a patient match CE marked implant (ORIGIN®) versus off-the-shelf (VANGUARD PS) device, and to document the clinical and device performance outcomes of the ORIGIN System used in routine hospital practice in a large patient cohort treatment of total knee arthroplasty.
