The basic science and clinical applications of osteochondral allografts.

Abstract

Indications for the use of osteochondral allografts for orthopaedic surgical applications are increasing with improved surgical techniques and advancing experience. Modern tissue banks have developed harvesting, processing, and storage methods that ensure an adequate, safe supply of grafts. Continued research is necessary to find a technique that maximizes chondrocyte viability and metabolism both during storage and implantation. The majority of published data on the use of osteochondral allografts has focused on the management of osteochondral defects about the knee. Successful outcomes following these procedures have led to increased interest in their application to pathology affecting other joints including the shoulder and ankle. The current paper aims to review the basic science and clinical applications of osteochondral allografts.
