Abstract
The task of the orthopedic surgeon is not just to perform the implantation of joint replacement (arthroplasty), but also to use the implant with the longest life expectancy possible. One of the key factors influencing life of joint replacements are properties of materials used for production of articular surfaces.
Polyethylene of ultra high molecular weight (Ultra High Molecular Weight polyethylene) is still the gold standard among these materials. Preparation and sterilization of Ultra High Molecular Weight polyethylene can significantly influence their tribological properties and thus the life of the whole prosthesis.
Measurement of selected parameters of material components (such as oxidation index, transvinylen index and crystallinity) can identify those most suitable for implantation - and thus positively affect life expectancy. The method, developed in cooperation with Institute of Macromolecular Chemistry, Academy of Sciences, precisely identifies these parameters and provides information to enable an objective comparison.
So it is possible to protect the patient from the dangers of early implant failure and reduce the risk of reoperation, which is always a challenging operating performance combined with a heavy load.
