The purpose

Total Knee Arthroplasty (TKA) is the surgical reconstruction of the knee joint in order to relieve pain, restore function and correct deformity. It is a very common surgical procedure with figures showing more than 500'000 arthroplasties performed annually worldwide. Total knee arthroplasty is considered one of the most successful types of joint reconstruction in that surgical results usually meet and even exceed expectations. Much of the current literature focuses on the issues relating to implant wear as a potential failure mode for artificial knee implants. It has been suggested that knee with mobile or rotating bearing options, such as the comparative device proposed for this clinical investigation, may survive longer than fixed bearing knee designs because of the greater contact surface area possible with more congruent components with unconstrained, mobile component design.

Provided treatments

  • Device: mobile bearing knee system for total knee arthroplasty
  • Device: fixed bearing total knee prosthesis
