Abstract
The invention relates to a knee joint orthosis with a thigh shell (2) fastenable to thigh (1) of the patient with bandages or the like, a lower leg shell (4) likewise fastenable by bandages or the like to lower leg (3), and with two joint rods (5), said rods being located laterally opposite one another, approximately parallel with the leg extended, and connecting the two leg shells (2, 4) with one another with articulation, each of said rods being operatively connected at its upper end by an upper articulation point (8) with thigh shell (2) and at its lower end by a lower articulation point (10) with lower leg shell (4) in such manner that the distance between the two articulation points (8, 10) decreases from a maximum with the leg extended to a minimum with the knee completely flexed. To simplify the design and the operation, it is proposed according to the invention that the pivoting of at least one joint rod (5) around its lower articulation point (10) from the extended leg position into a knee bend take place against a force opposing the pivoting, said force increasing up to a knee bend of about 30.degree. to 40.degree. and decreasing once again with an approximately 90.degree. bend (seated position).
