Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The infection rate after Total Hip Arthroplasty (THA) is about 1%. It is a serious condition, with high morbidity, sometimes fatal, requiring costly treatment.

The treatment is difficult because "biofilm" forms very early after the bacterial contamination of the prosthesis.

Prevent infection means reduce or prevent the formation of bacterial biofilm and controlling protein response to allow osseous-integration of the prosthesis.

A new prosthesis was developped, grafted by PolyNaSS (polysodium styrenesulfonate). This bioactive polymer allows to substantially reduce bacterial adhesion and increase biocompatibility and bio-integration in preclinical studies. This first clinical study aims to compare the osseous-integration of this prosthesis to the same prothesis with no grafting.
