Hyaluronic acid (HA) is a naturally occurring substance found in joint synovial fluid.  Its primary role is to act as a lubricant enabling smooth pain free articulation.

Ultra High Molecular Weight Polyethelyne (UHMWPE) is a biocompatible polymer with a long history of use in orthopaedic implants, primarily as the bearing material in total joint arthroplasty.

Utilizing a patented process these two materials have been combined to create an advanced orthopaedic biomaterial with exceptional wear properties and sufficient strength to support anatomical loading.

Advanced Properties

The BioPoly® material with its interpenetrated HA molecules give BioPoly enhanced lubricity over traditional UHMWPE contributing to lower wear rates and a lower coefficient of friction.

With the now hydrophilic (water attracting) surface the BioPoly material can better interface with hydrophilic tissues like natural cartilage.

BioPoly has sufficient strength to support anatomical loading yet it has a stiffness an order of magnitude less than implantable metals.
