Triathlon® Knee Replacement System

Stryker's Triathlon® Knee System represents the contribution of over 30 years of clinical success in orthopedic implants. It utilizes the latest in knee technology to help restore motion in your knee after surgery. The Triathlon® Knee is designed for natural knee movement, helping to decrease your pain and restore your independence. The Triathlon® Knee System has the potential to provide patients with:

  • Increased Motion1
  • Better Fit5
  • Reduced Wear2

Increased Range of Motion After Knee Replacement

Restoring motion in your knee is likely one of the reasons you are considering knee replacement. Motion, the bending (flexing), straightening (extension) and rotation of your knee, affects your ability to perform everyday activities. The Triathlon® Knee System allows for natural knee motion, with most patients achieving a 12-15% increase in motion after one year1.

Improved Wear Performance

A patient's weight and activity level affect how long a hip implant will last, as does the implant bearing surface (the portions of the artificial hip that glide together when you move). Stryker's new, advanced bearing technology, called X3®, has demonstrated a 96% decrease in wear in laboratory testing compared to competitive premium bearing technology.2 This decrease in wear may extend the life of your implant, which is particularly important for younger patients.

Better Fit

Triathlon® offers a wide range of sizing options that closely match both the female and male anatomy, allowing for individualized fit of knee components.

Knee Replacements with a Better Fit for Women

There are over 300,000 knee replacements done each year in the US3 and over 60% of them are performed on women4. Triathlon® is a total knee system designed with women in mind.5 Triathlon® offers a wide range of sizing options that closely match both female and male bodies. The smaller sizes are designed to be narrower, accommodating the female bone structure, which has the potential to improve fit and function for women.
