Inserts & Bearings

Engineered for low contact stress throughout the range of motion, Conformis knee replacement systems are designed to reduce the risk of polyethylene wear. We use the latest material technology for stronger and more durable polyethylene inserts, and offer two types of polyethylene material: iPoly, and iPoly XE.

iPoly

iPoly (GUR1020) is a time-tested polyethylene used in standard total knee systems for over 30 years. While maximizing contact area and conformity to the patient-specific femoral implant, iPoly has favorable wear rates and provides implant longevity.

iPoly XE

iPoly XE (highly crosslinked vitamin-e infused UHMWPE) is the next generation of highly cross-linked polyethylene blended with Vitamin E.
