What Materials Are Used In The Stryker Triathlon Total Knee System?

The Triathlon Total Knee System beaded and beaded with Peri-Apatite components are intended for uncemented use only. The Triathlon Tritanium Tibial Baseplate and Tritanium Metal-Backed Patella components are indicated for both uncemented and cemented use.

What metal is used in a Stryker knee?

  • Metal components usually consist of titanium or cobalt-chromium based alloys. These materials are known for their durability, and have stable (inert) chemical properties such that they do not interact with the body.

What is the Stryker Triathlon knee made of?

> The Triathlon Tritanium Metal-Backed Patella* features Stryker’s Tritanium 3D porous metal technology, made from commercially pure titanium, on the metal underside of the patella. > The Triathlon Tritanium Metal-Backed patellar components* are available with conventional polyethylene.

What material is used for total knee replacement?

The metal parts of the implant are made of titanium- or cobalt-chromium-based alloys. The plastic parts are made of medical grade polyethylene. Some implants are made of ceramics or ceramic/metal mixtures such as oxidized zirconium. These implants typically weigh between 15 and 20 ounces.

What are the components of a total knee?

Total knee replacement surgeryTotal knee replacement consists of three main components: the femoral component, the tibial component, and the plastic spacer (polyethylene).

What metal is used in Stryker knee replacement?

Tritanium Baseplate, Tritanium Metal-Backed Patella and CR PA beaded femurs were used.

Is the ACL removed during total knee replacement?

During a traditional total knee replacement, the surgeon must remove the “island” of bone to which the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL) are attached. The new knee features a shape that protects that island of bone and saves the ligaments.

What plastic is used in knee replacement?

Polyethylene (PE) has been used extensively in knee arthroplasty since the mid 20th century.

Is there a plastic knee replacement?

The doctor will remove the damaged surfaces of the knee joint and resurface the knee joint with the prosthesis. The knee prosthesis is made up of metal and plastic. The most common type of artificial knee prosthesis is a cemented prosthesis.

What is the latest technology in knee replacements?

This latest advancement in joint replacement surgery transforms the way knee replacements are performed. “ The Mako system is a revolutionary tool to help joint surgeons be more precise in placing implants to achieve the most appropriate, balanced position possible,” explained orthopedic surgeon Harold Cates, MD.

What are the three components of the knee?

Knee joint: The knee joint has three parts. The thigh bone (the femur) meets the large shin bone (the tibia) to form the main knee joint. This joint has an inner (medial) and an outer (lateral) compartment. The kneecap (the patella) joins the femur to form a third joint, called the patellofemoral joint.

What are artificial joints made of?

It is generally accepted that artificial joint materials include metal, polymer and bioceramics. Ultra-high-molecular-weight polyethylene (UHMWPE) is the main polymer used for joints, and it is widely used as acetabular cup material due to its superior biocompatibility, high impact strength and non-toxicity.

How long will a Stryker knee replacement last?

In 85% to 90% of people who have a total knee replacement, the knee implants used will last about 15 to 20 years.

What is the best knee replacement?

A TKR is now among the safest and most effective of all standard orthopedic surgeries. During a TKR, a surgeon removes the surface of your bones that have been damaged by osteoarthritis or other causes and replaces the knee with an artificial implant that is selected to fit your anatomy.

Are all knee replacements titanium?

All knee replacements, partial or total, will have parts made of a few different materials (likely metals and plastic). In most cases, each component is built from titanium, cobalt-chromium alloys, or a titanium and cobalt mixed metal.
