As recently reported in the 4/09 issue of New Scientist, medical researchers at the Weizmann Institute of Science in Rehovot, Israel have developed a synthetic cartilage able to withstand pressures that caused previous synthetic cartilage to function more poorly.

The key to synthetic cartilage success lies in its ability to withstand greater pressure associated with high impact activities while still maintaining its fluidness and flexibility.

This new polymer uses molecular brushes that are capable of attracting water to minimize the friction produced with the gliding motion of joints. Consequently, the cartilage remains well lubricated.

Although still in its experimental stages, if successful, this new material may provide relief for millions of people who suffer from osteoarthritis.
