Measurement of the Quality of Life in Patients Operated With a Total Knee Prosthesis (TKA) From the FHK® Range.

Study Overview
=================
Brief Summary
-----------------
As part of Medical Devices CE marking regulatory process, an appropriate post-market clinical follow-up (PMCF) is required. This PMCF study is in the framework of CE mark renew of FHK® total knee prosthesis, it aims to answer specific questions related to safety and performance of the device, when used in accordance with the approved instructions for use. This study is based on a quality of life self-assessment from the preoperative to postoperative phases and up to two years of follow-up.

Detailed Description
-----------------
The primary objective of this study is to evaluate the quality of life in patients operated with a FHK® total knee prosthesis up to 2 years of follow-up. The secondary objectives are to evaluate the security and performance of the devices by gathering complications, revision rate of the devices (survival analysis) and functional score up to 2 years of follow-up.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Quality of life EQ-5D-5L score | The primary outcome measures will be determined by the EQ-5D-5L score. The EQ-5D-5L score is a self-administered quality of life questionnaire by patients. The EQ-5D-5L consists of two parts, One part with a five-dimensional system and the last one is a visual analog scale graduated from 0 to 100. We will observe the evolution of this score according to the time frame. | 14 days preoperative ; 70 days post-op, 177 days post-op, 357 days post-op, 717 days post-op | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Survival rate |  | 2 years post-op | 
| Evolution of parameters describing pain, stability, knee mobility and patient autonomy | The secondary outcome measures will be determined by the KOOS-PS score, a patellar evaluation, and questions about physical abilities. The KOOS-PS score is a score used in the clinical evaluation of various knee pathologies.This score assesses both the long and medium term consequences of a knee injury. It contains 42 items in 5 separately scored subscales (pain, other symptoms, function in daily life, function in leisure and sports and quality of life related to the knee). The patellar evaluation is a questionnaire assessing the functional state of the knee with questions such as the level of pain in the anterior region of the knee, assessment of the strength of the quadriceps, the ability to rise from a chair. Physical abilities will be assessed with questions like the patient's walking distance, the ability to cycle, the ability to go shopping. | From the preoperative visit to 2 years postoperative. | 
| Rate of complications |  | All complications will be gathered during intervention and up to 2 years postoperatively. |
