Abstract:
A cartilage replacement apparatus. This apparatus is a hollow plastic pad with a load bearing material within the plastic pad. The load bearing surface provides the shock absorbing compliance of natural cartilage and is effective in absorbing the peak contact stresses imposed on a prosthesis when placed in an extreme, load bearing situation. The unique characteristics of the invention makes it a permanent replacement for cartilage, thus permitting patients to avoid further replacement surgery. It also would provide a unique bearing surface for total joint replacement surgery, such that it would obviate the destructive effects of particulate debris.
