Triathlon TS Knee System
The Triathlon TS Knee System is designed to provide Triathlon performance in a streamlined revision procedure. (A revision system designed to provide stability without compromising performance.) The intuitive and evolutionary design is based on the worldwide clinical success of the Triathlon Primary system and millions of Stryker knee implantations. The Triathlon TS Knee System is designed to provide improved motion,1 better fit2 and the potential for greater implant longevity.3,4
The Triathlon TS Knee is an evolutionary design developed for mobility with stability through 135 degrees of flexion.5
Features & Benefits
- 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.
- The only revision system with size offerings based on an anthropometric measurement study for excellent 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.
- The forgiving design aspects of the implant helps accommodate surgical realities.
- 360 degree radial offsetting for both the femur and tibia potentially allowing for more stability, ligament balancing, and optimal bone coverage.
Potential for Greater Implant Longevity
- 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.
- Limited incision capabilities.
- 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.
- Reduced number and size of trays.
- Quick offset determination.
- Simplified implant assembly.
- Joint line ruler to help restore correct joint line.
- Reduced weight of the instrument set as compared to legacy systems.
- Streamlined instrumentation, including downsized femoral and tibial cutting blocks that have the potential to minimize soft tissue impingement.
