| Popis: | Background Due to the rising interest in Europe to treat large cartilage defects with osteochondrale allografts, research aims to find a suitable solution for long-term storage of osteochondral allografts. This is further encouraged by the fact that legal restrictions currently limit the use of the ingredients from animal or human sources that are being used in other regions of the world (e.g. in the USA). Therefore, the aim of this study was A) to analyze if a Lactated Ringer (LR) based solution is as efficient as a Dulbecco modified Eagle’s minimal essential medium (DMEM) in maintaining chondrocyte viability and B) at which storage temperature (4 °C vs. 37 °C) chondrocyte survival of the osteochondral allograft is optimally sustained. Methods 300 cartilage grafts were collected from knees of ten one year‐old Black Head German Sheep. The grafts were stored in four different storage solutions (one of them DMEM-based, the other three based on Lactated Ringer Solution), at two different temperatures (4 and 37 °C) for 14 and 56 days. At both points in time, chondrocyte survival as well as death rate, Glycosaminoglycan (GAG) content, and Hydroxyproline (HP) concentration were measured and compared between the grafts stored in the different solutions and at the different temperatures. Results Independent of the storage solutions tested, chondrocyte survival rates were higher when stored at 4 °C compared to storage at 37 °C both after short-term (14 days) and long-term storage (56 days). At no point in time did the DMEM-based solution show a superior chondrocyte survival compared to lactated Ringer based solution. GAG and HP content were comparable across all time points, temperatures and solutions. Conclusion LR based solutions that contain only substances that are approved in Germany may be just as efficient for storing grafts as the USA DMEM-based solution gold standard. Moreover, in the present experiment storage of osteochondral allografts at 4 °C was superior to storage at 37 °C. |
