Polycentric dynamic orthosis for knee joint, has two disc plates with articulated points linked to femoral and tibial arms to place arms between plates, where points reproduce diagram of physiological contact points between femur and tibia

摘要

The orthosis has an articulated device with disc plates (1, 2) having articulated points (1a, 1b, 2a, 2b). The lower end of a femoral arm (3) is connected to the points (1a, 2a) and the upper end of a tibial arm (4) is connected to the points (1b, 2b). The points (1a, 1b, 2a, 2b) are disposed to reproduce the diagram of successive physiological contact points between femur and tibia. The ends of both arms are placed between the plates.
