with Triathlon

Triathlon and the single radius are designed to work with the patient’s body. Studies have shown that Triathlon and the single radius offer:

  • Stability82-85
  • Satisfaction86
  • Survivorship87-90

Stability

The Triathlon single radius is designed to restore the knee’s single center of rotation during active flexion, where most motion occurs.91-92 This allows for constant ligament tension and stability in flexion.82-85

Normal gait patterns

In a study from 2015, Triathlon patients exhibited gait that closely mimicked that of healthy control subjects. However, the multi radius knee differed from controls in important knee kinetic and kinematic properties.84 The single radius knees had a significantly greater percentage of the stance phase where muscles were firing independently when compared to the single multi radius design. Another fluoroscopic study on Triathlon patients showed the femoral component was kinematically stabilized in mid-flexion ranges and posterior femoral rollback occurred in deeper knee flexion with this knee design.85

Fluoroscopic data has shown that the medical pivot is possible without features that drive a medial pivot.85


PS kinematics

The Triathlon PS femur is designed to engage the post of the tibial insert at approximately 45°, where natural PCL loading occurs.78

Survivorship

Multiple studies88,90 and joint registries87,89 from around the world consistently show high rates of survivorship with Triathlon.

X3

Patented sequential irradiation and annealing process39 allows for:

  • Mechanical Strength96
  • Wear Resistance97
  • Oxidation Resistance42

Increased survivorship with X3 was supported by multi center study and joint registry reported at 5 years follow up.96

System options

The Triathlon knee system offers surgeons a variety of options depending on disease, deformity, and demand.
