What material is the Stryker knee made of?

Triathlon Tritanium combines the kinematics of Triathlon with the latest in highly porous biologic fixation technology. Tritanium’s innovative tibial baseplate and metal-backed patella components are SOMA-designed and enabled by Stryker’s proprietary Additive Manufacturing technology.

What is Triathlon knee replacement made of?

The polyethylene used in the TKR is from the X3 Stryker modern polyethylene range. The Triathlon knee replacement also has shortened and flared posterior condyles designed to allow a potential 150 degrees of flexion.

What metal is used in Stryker knee replacement?

What metal is used in a total knee replacement?

The metal parts of the implant are made of titanium or cobalt-chromium based alloys. The plastic parts are made of ultra high molecular weight polyethylene. Some implants are made of ceramics or ceramic/metal mixtures. Whether metal or ceramic, implants weigh between 15 and 20 ounces, depending on the size selected.

Are knee replacements metal or plastic?

The metals used in artificial knees are alloys of cobalt-chromium and titanium. The bearing portion of the joint is made of a high-grade, wear- resistant plastic. The metal-plastic bearing combination is the most common type used in knee replacement implants worldwide.

What are the disadvantages of a knee replacement?

Disadvantages. Possible disadvantages of knee replacement surgery can include replacement joints wearing out over time, difficulties with some movements and numbness. We now know that knee replacements aren’t so likely to be effective in the early stages of arthritis.
