Résumé
Background: In equine species, meniscal tears are frequent as soft tissue injuries in the stifle and can be responsible for the premature ending of careers of sporting horses due notably to the concomitant presence of degenerative articular disease [1, 2]. In humans, Pauli and collaborators [3] demonstrated a correlation between osteoarthritis grades and meniscal degeneration. Objectives: Our objective was to evaluate the putative macroscopical and histological changes on equine menisci with various grades of stifle osteoarthritis. Materials and methods: Menisci were taken at necropsy, 1-48 h post mortem, from two mares aged 11 and 13 years, respectively and with body weight of approximately 590 kg. Macroscopical and microscopical grading systems were used (Table Proteoglycans were revealed with Safranin-O, the collagen fibers organization with Fast Green and cell's nuclei with Weigert's Iron Hematoxylin. Results: Macroscopically, the "low chondropathy horse" (LCH) (Fig. For both, a "swelling and softening of the cartilage with a light brown homogeneous coloration"
