Triathlon TS Knee Revision System

• Incorporates all of the enhanced features from the primary Triathlon system with the stability required of a revision knee system.
• Design features such as a patented single radius, deep flexion radius and flared posterior condyles, as well as an anatomic patellofemoral track allow the Triathlon TS knee system to maintain substantial contact area throughout the entire range of motion.
• The deep flexion features of the components are designed to allow up to 135 degrees of flexion without sacrificing stability.
• Enhanced rotary arc that allows for 7 degrees of internal/external rotation.
• Improved quadriceps efficiency that has the potential to facilitate a quicker return to function.

• Size offerings based on an anthropometric measurement study for interplay between implant geometry and anatomic structure.
• Optimized femoral boss position designed to better match femoral canal location.
• Offers a broad range of tibiofemoral sizing options to meet the anatomic realities of TKR.
• 360 degree radial offsetting for both the femur and tibia potentially allowing for more stability, ligament balancing, and optimal bone coverage.

• The revision system with advanced bearing technology – X3.
• A high degree of conformity throughout the range of motion is designed to reduce the contact stresses and wear, offering the potential for enhanced long-term component durability.
• Single radius design and early cam engagement provides potential reduction in insert wear.
• A precision insert locking mechanism and Anti-Rotation Island addresses insert micromotion and increases insert/tibial tray contact surface area – all designed to decrease the likelihood of backside wear.
• Patent pending post-preserving features.

The proprietary instrumentation design also delivers intra-operative flexibility. The following features accommodate surgical preferences and help surgeons and staff adapt to multiple surgical realities:

• A common platform that is designed to allow for seamless intra-operative transitions.
• One-step transition from PS to TS.

The Triathlon TS knee system Instrumentation design team focused on identifying ways to increase the accuracy and simplicity of the surgical procedure, two variables that may affect OR efficiency. The features incorporated include:

• An IM Reamer referencing based system.
• Color coding of trials for ease of use and clear identification.
• Quick attach and release mechanisms to facilitate easy assembly.
• Streamlined tray layout based on operational sequence.
• Quick offset determination.
• Simplified implant assembly.
