The Triathlon knee system from Stryker is a popular total knee replacement. It is an ODEP (Orthopaedic Data Evaluation Panel) 10A rated (10 year survivorship with a maximum of 7% revision rate) prostheses with good results in the National Joint Registry of England and Wales and has a failure rate of only 3.22% at ten years. The philosophy of the Triathlon is that is has a single radius of curvature  which increases the range of motion of the knee replacement. A single radius implant may lead to improved extension and therefore less quadriceps force when extending the knee. A single radius knee design may also improve the ligamentous balance of the collaterals throughout the full range of motion of the knee system. The polyethylene used in the TKR is from the X3 Stryker modern polyethylene range. The Triathlon knee replacement also has shortened and flared posterior condyles designed to allow a potential 150 degrees of flexion.
