Triathlon PSR Outcomes Study

Stopped early · Not applicable

Conditions studied: Arthroplasty, Knee

In brief

This study is a prospective, open-label, post-market, non-randomized, multi-center clinical evaluation of the Triathlon Total Knee System using the Triathlon PSR Tibial Insert for primary total knee arthroplasty (TKA) in a consecutive series of patients who meet the eligibility criteria. The SF-36 score of subjects receiving the Triathlon Total Knee with the Triathlon PSR insert is expected to be comparable with that of subjects receiving historical Triathlon PS cemented constructs.
