【 摘 要 】

We evaluated the mechanical properties, strength, strain and stress to the elastic limit, the rupture stress point and stiffness index of fresh menisci and menisci transplanted for 70 days in the knees of rabbits after preservation in glycerin. The first group (treated) was formed by six medial menisci of the left knee, collected from these animals for commercial breeding. These menisci were stored in 98% glycerin for a period of 30-60 days, and then rehydrated in a solution in 0.5% saline enrofloxacin for 12 hours, and implanted in the knees of another six rabbits underwent meniscectomy . After 70 days of surgery was performed the euthanasia of animals and removal of allografts for mechanical evaluation. The second group (control) consisted of six medial menisci, removed from the contralateral knees (right) of the same animals. For the sample studied, had no statistically significant difference between control and treated groups for any of the variables analyzed, showing that the rehydration of meniscal allografts after preservation in glycerin keeps the mechanical characteristics of these, after 70 days of implantation, similar to the meniscus fresh.
