| Sumario: | To investigate the morphologic aspects and the relations of the articular muscle of the knee with articular cavity of the knee, as well as the disposal of muscular fibers to the level of femur, besides comparing the muscular mass of the articular of the knee with the rest of the muscular mass of the inferior member, 15 inferior members of adult human corpse of both sex, settled in formol and transversally parted, in middle third of the thigh and in proximal third of the leg, had been analyzed. The study method was of macroscopic dissection. The articular muscle of the knee was present in all the analyzed material and in 93.3% of the cases it had its proximal point of attachment in the distal anterior portion of femur. Amongst analyzed specimens, 40% had shown a sufficiently reduced muscular mass and a trapezoidal type. This muscle presented a distal insertion at an average distance of 3.07cm above of the superior edge of the trochlea and an anterior insertion in proximal edge of the suprapatellar bursa. The number of bundles of each muscle varied from 2 to 7 bundles which, in its majority, had presented a vertical direction. The muscle showed an anterior position on the distal third of the femur. Our results suggest that the same size and the relations of this with the suprapatellar bursa can be directly related with the rest of the muscular mass of the member of the individual, therefore when it works to increase muscular tonus of the quadriceps, it is also, in indirect way, increasing the articular muscle of the knee and improving its performance in the articular cavity |
