Evaluation of a New Bi-Condylar Total Knee Prosthesis (TKP) With All-Ceramic Friction (The Forgotten Knee)

Recruiting now · Not applicable

Conditions studied: Knee Osteoarthritis

In brief

The results of TKP (Total Knee Prosthesis) are satisfactory but do not reach those of THP (Total Hip Prosthesis) in terms of indolence and function. By using an all-ceramic friction torque, identical to that of the hip, the promotor of this Clinical Investigation expects to obtain an improvement in term of indolence, ability to perform heavy activities, knee stability and an improvement in the long-term survival of TKP, while at the same time, a decrease in the rate of re-intervention in young patients.
