This clinical investigation was led as a post-market clinical follow-up study (post-market device development stage).The main objective of this study is to collect short- and medium-term clinical data on the unicondylar knee prosthesis U-Knee / Uni-Kroma, in order to evaluate the performance of these implants.
None
Patients who objected to participating in the study and the processing of their data
Patients unable to understand the surgeon's instructions to complete their questionnaires or perform postoperative follow-up
Patients who already have a unicompartmental prosthesis on the knee in question that need to be revised.
Male or female adult for whom a unicondylar knee prosthesis is indicated according to U-Knee / Uni-Kroma instructions for use. Patients will be followed according to current practice
Cohort
Prospective
Unicompartmental knee arthroplasty
DeviceKnee joint could be subject to natural or pathological wear or shocks (primary or secondary evolutive or traumatic osteoarthritis) which cause pain and reduced mobility of the knee. When only one lateral or medial compartment of the femoro-tibial knee joint is affected, the treatment of unicompartmental femoro-tibial osteoarthritis of the knee is generally carried out by the implantation of a so-called unicondylar knee prosthesis (UKP), in order to reduce pain and improve joint mobility of the knee compared to the preoperative state.
