Brief summary

This study is a post-market clinical follow-up conducted in order to collect long-term data on security and performance of the FHK asymetrique prosthesis, which is intended to be implanted in case of total knee replacement, when used in real life conditions according to the instructions for use.

Detailed description

The primary objective of this study is to evaluate the security of the FHK ASYMETRIQUE prosthesis by calculating the survival rate up to 10 years of follow-up. The secondary objectives are to evaluate the security and performance of the device by assessing radiological data, gathering complications and evaluating functional score up to 10 years of follow-up.

Interventions

DEVICEKnee prosthesis - FHK ASYMETRIQUE total knee prosthesis

FHK ASYMETRIQUE prosthesis are intended to be implanted in the tibial and femoral regions during total knee arthroplasty in order to restore joint function.

Design outcomes

Primary

Measure	Time frame	Description
Safety evaluation	10 years post-op	Survival rate

Secondary

Measure	Time frame	Description
Radiological evaluation	preoperative, 3 months post-op, 1 year post-op, 3 years post-op, 5 years post-op, 10 years post-op	Radiological results such as stability, osteointegration will be evaluated. The HKA angle will be measured. It is the angle (in degrees) between the center of the femoral head, the center of the knee and the center of the tibio-fibular mortise. This radiological evaluation is a usual assessment used in the follow-up of patients operated for a total knee replacement.
Rate of complications	peroperative, 3 months postoperative, 1 year post-op, 3 years post-op, 5 years post-op, 10 years post-op	All complications will be gathered during intervention and up to 10 years postoperatively.
Functional outcomes such as pain, mobility.	preoperative, 3 months post-op, 1 year post-op, 3 years post-op, 5 years post-op, 10 years post-op	Functional outcomes will be determined by the IKS score. New IKS score range from 0 to 200 with a physical score on 100 points (pain, knee's mobility, abnormal laxity, flexion deformity and Hips knee Ankle) and a functional score on 100 points (walking distance, difficulty with stairs and use of walking aids).
