METHOD OF PRODUCING PROSTHESES FOR REPLACEMENT OF ARTICULAR CARTILAGE AND PROSTHESES SO PRODUCED

摘要

Prostheses useful for articulating cartilage replacement, and which are attached to host bone without the use of cements, are derived from bone. Allogenic or xenogenic bone segments are machined into the desired shape and differentially demineralized. The completely demineralized portion has a spongy texture similar to natural cartilage, while the non-demineralized portion is a matrix into which adjacent host bone grows, thus anchoring the prosthesis. The prostheses are tanned which renders the material non-antigenic, biocompatible, and stable.
