Triathlon Total Knee Replacement System
The Triathlon Knee System is designed to meet patients’ expectations for Lifestyle Recovery. The intuitive and evolutionary design is predicated on the worldwide clinical success of millions of Stryker knee implantations. The Triathlon Knee System is designed to provide patients more natural motion and the potential for greater implant longevity. The Triathlon Knee is an evolutionary design developed to more closely reproduce natural knee motion, designed to provide mobility with stability through 150+ degrees of flexion.
The Triathlon Knee System Instrumentation has been developed based on Stryker’s 30 year orthopaedic history. The system combines the engineering expertise of Human Factors Engineers with the experience of surgeons and OR staff worldwide. The Triathlon Knee System Instrumentation provides optimal OR efficiency and intra-operative flexibility through an Orthonomic design.
Features & Benefits
- Design features such as a patent pending anatomic radius, deep flexion radius and flared posterior condyles, as well as Rotary Arc and anatomic patellofemoral track allow the Triathlon Knee System to maintain substantial contact area throughout the entire range of motion.
- The deep flexion features of the components are designed to optimize rotation in deep flexion without sacrificing stability.
- The femoral geometry in conjunction with the Rotary Arc accommodate increasing amounts of internal/external rotation as necessitated by greater degrees of flexion.
- Size offerings are based on an anthropometric measurement study for optimal interplay between implant geometry and anatomic structure.
- Offers a broader range of tibiofemoral sizing options to meet the anatomic realities of TKA.
- A 7-degree anterior flange is designed to enable downsizing with lower incidence of notching.
- The forgiving design aspects of the implant accommodates surgical realities.
Reduced Wear3 / Potential for Greater Implant Longevity
- Designed to limit contact stresses even in adverse conditions.
- A precision insert locking mechanism and Anti-Rotation Island inhibits insert micromotion and increases insert/tibial tray surface contact area - all designed to decrease the likelihood of backside wear.
- A high degree of conformity throughout the entire range of motion is designed to reduce contact stresses and wear, offering the potential for enhanced long-term component durability.
The Triathlon 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:
- Open design cutting blocks to enhance visualization.
- Bold markings and color coding for ease of use and clear identification.
- Quick attach and release mechanisms to facilitate easy assembly.
- A logically organized tray layout based on the operational sequence for a streamlined process.
The proprietary instrumentation design also delivers intra-operative flexibility. The following features accommodate surgical preferences and help surgeons adapt to multiple surgical realities
- System modularity facilitates a customized surgical flow.
- A common platform that is designed to allow for seamless intraoperative transitions.
- Navigation ready.
- Minimal incision capability.
The Triathlon Knee System Instrumentation is designed to be the new gold standard in the industry. Advanced design principles incorporating Orthonomic features include:
- Ergonomic soft grip handles for optimized fit and comfort.
- Instrument surface treatment for reduced glare and enhanced readability.
- Procedural enhancing mechanisms.
- Lightweight trays for ease of handling.
