Geometric Evaluation of Fresh Menisci and Menisci Preserved in 98% Glycerin: Study in Rabbits (Oryctolagus cuniculus)

Abstract

Meniscus alloimplants have been used as a source of tissue for replacement in case of breakage or irreparable damage. To determine possible changes by conservation, the study proposed to geometrically evaluate fresh menisci and menisci preserved in 98% glycerin. 15 medial menisci from eight albino rabbits of New Zealand breed were used, divided into three groups: five fresh menisci (GI); five menisci preserved in 98% glycerin for eight months (GII), and five menisci preserved in 98% glycerin for eight months and then rehydrated in 0.9% saline solution for 24 hours (GIII). All menisci were measured with vernier caliper at seven points of their geometric structure. The study established that there were no statistical differences in the measurements of GII and GIII when compared to GI; there was no difference either in the measurements of GIII when compared to GII, thus rehydration in antibiotic saline solution for 24 hours can be considered unnecessary.
