ABSTRACT
PURPOSE:
To determine the viability of human chondrocytes within refrigerated articular cartilage stored under conditions currently used clinically. MATERIALS ANDMETHODS:
Osteochondral sections of human ankle taluses were stored at 4 degrees C in DMEM media for 1 to 42 days. Articular cartilage was harvested and evaluated for histologic changes and proteoglycan synthesis.RESULTS:
By day 7, markedly decreased proteoglycan synthesis was observed. After 21 days, synthetic activity was virtually undetectable. Histologic specimens demonstrated chondrocyte death of a half of the cells from the superficial layer at day 7. Within 21 days, significant chondrocyte death was seen.CONCLUSION:
These results suggest that proteoglycan synthetic activity and chondrocyte viability are markedly decreased in articular cartilage after cold storage for longer than 7 days.
