The menisci are injured mainly for two reasons, these are: metabolic problems or traumatic type by tears. Statistics show that the most frequent incidence of injury is at the junction of the meniscus to the tibial plateau, which corresponds to the horns thereof; sometimes these connections are compromised by the failure of the jugal ligament. Our study will focus efforts on the horns of the menisci, as these limits to some extent the movement of the meniscus on the glenoid.\nSix adult knee joints were obtained, which were frozen at -20 °C until the day of the test.. The specimen was loaded into natural direction and the fibers were aligned parallel to the load direction. To characterize the material properties of the joints of the meniscus, the linear stiffness N/mm, the elastic modulus MPa, destructive load N, the final displacement mm, ultimate strain in % and last effort MPa, were determined. The analysis of the distribution of the deformation was made for three unions, which are anterior lateral (L-A), anterior media (M-A) and posterior media (M-P) sides. The average cross sectional area to test all joints was determined to be approximately 109 mm2. The average length of the three joints was estimated at: 14mm, 15mm and 16.5mm for M-A, M-P and L-A junctions respectively. The average linear stiffness of the three joints were found to be 420 N/mm 190 N/mm and 325 N/mm for L-A, M-A and M-P joints respectively. The last effort of the joints L-A and M-A, yielded values of 20 MPa and 11.5 MPa respectively. The average failure loads of the three joints resulted in 2500 N, 1082 N and 1500 N for L-A, M-A and M-P, respectively.
