Clinical Trial Summary

The main objective of this study is to evaluate the benefit of personalized prostheses compared to conventional prostheses on patient satisfaction 24 months after total knee arthroplasty.

Description:

Prospective randomized monocentric prospective comparative study carried out as a single blind study on two parallel groups (standard implant or customized implant).

Secondary Objectives: Compare between groups :

• the functional outcome of the arthroplasty

• pain progression

• the evolution of the quality of life

• the conditions of the surgery (duration of surgery, length of hospitalization, blood loss)

• the frequency of adverse events related to arthroplasty

Exclusion Criteria:

• History of knee arthroplasty or osteotomy

• History of knee fracture

• Inflammatory rheumatic disease or any other progressive concomitant disease that may affect the patient's functional prognosis.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	IKS self-questionnaire Score at M24	The score obtained on the IKS self-questionnaire at 24 months will be compared between the two treatment groups by an analysis of covariance, with the basal IKS score as a covariate and the type of prosthesis as a factor.	24 MONTHS
Secondary	SF12 score at M24	The comparison between groups will be made on the evolution of scores, in relation to the baseline value, by an analysis of covariance with treatment and time as fixed factors, the subject as a random factor and the baseline value as a covariate. The interaction Time x Treatment will be added to the model. The effects of time and treatment will be tested at each evaluation point.	24 months
Secondary	KOOS Score at M24	The comparison between groups will be made on the evolution of scores, in relation to the baseline value, by an analysis of covariance with treatment and time as fixed factors, the subject as a random factor and the baseline value as a covariate. The interaction Time x Treatment will be added to the model. The effects of time and treatment will be tested at each evaluation point.	24 months
Secondary	Forgotten Joint Score at M24	The comparison between groups will be made on the evolution of scores, in relation to the baseline value, by an analysis of covariance with treatment and time as fixed factors, the subject as a random factor and the baseline value as a covariate. The interaction Time x Treatment will be added to the model. The effects of time and treatment will be tested at each evaluation point.	24 months
