Abstract: The purpose of this study was to analyze a protocol for freezing whole cartilage and to study the viability of cartilage after the implant in 60 knees of 45 New Zealand rabbits from a genetically impure population. Osteocartilaginous implants were removed, measuring 4 mm in diameter and 2-3 mm thickness, inclunding the articular cartilage and the suchondral bone, and slow freezing up -196º using Planer Kyro-10, Series II, Controlled Rate Freezers, following a controlled drop in temperature under cyrso-protection with Dimethylsulfoxide, propanediol and sacarose. After thawing grafts were implanted in femoral condyles. The implants evolves into an acellular amorphous tissue and after 2 months, period in which the incorporation of the osseous compound occurs, substitute fibrocartilaginous tiusse develops. This study shows that frozen articular cartilage does not remain viable after implant.
