Abstract

A novel hydrogel has been developed to potentially replace damaged articular cartilage. The purpose of this study was to quantify mechanical properties of the hydrogel relative to those of native articular cartilage. Preliminary tests have shown that the material possesses similar viscoelastic characteristics to those of natural cartilage. Further testing is being done to optimize the hydrogel formulation, thereby improving its capabilities
