A Silicone-Impregnated Knee Joint as a Natural Model for Arthroscopy
Klaus TiedemanSummary
After distention of the joint capsule by formalin injection, a knee joint can be plastinated and used as a natural model for arthroscopy. Maintaining a distended capsule during the curing of the impregnation polymer provides a well-defined and permanently expanded joint cavity. The whole process, including a second defatting and impregnation (required for a completely acceptable specimen), takes 10 weeks. While not an exact model of natural structure, the plastinated knee joint specimen provides many important advantages in arthroscopy training.
