Pre-operative
​
What materials are used in the replacement implants?
​
-
The replacement parts are made out of metal and plastic. A cobalt-chrome metal cap is placed over the end of your femur (thigh-bone), and a cobalt-chrome or titanium tray is placed atop your tibia (shin bone). A polyethylene plastic piece is placed in between them as part of the joint. If the knee cap is arthritic, a plastic button is also placed over it.
​
I have a metal allergy. Am I still a joint replacement candidate?
​
-
True metal allergies are rare, even in patients who develop rash when skin is in prolonged contact with metal. Moreover, the titantium and cobalt-chrome used in joint replacement implants are biologically inert. If you believe you have a true metal allergy, testing by an allergist doctor can be performed, which usually confirms that an allergy is not present. In the event major concerns persist, specialized zirconium-coated implants exist that envelope the metal surfaces.
