The invention relates to a method for controlling an artificial orthotic or prosthetic knee joint, on which a lower leg component is arranged and which is assigned a resistance device having at least one actuator, by means of which the bending resistance is modified depending on sensor data that is determined during use of the orthotic or prosthetic knee joint by means of a sensor, wherein the absolute angle of the lower leg component is determined exclusively by means of at least one inertial sensor, the angle determined is compared with at least one threshold value, and the bending resistance is modified when the threshold value is reached.. .

Anti-septic transarticular intramedullary rod system for the human knee

A temporary knee implant to be placed at the position of the human knee joint for maintaining the tibia and femur at the knee joint aligned during healing of infection in the surrounding tissue. An elongated femur rod is formed with one end of a breadth sized and shaped to extend into the medullary cavity of the femur of a knee, and a connector at the other end, an elongated tibia rod of a breadth sized and shaped to extend into the medullary cavity of the tibia and a connector at the other end, the connectors including interfitting shapes for aligning said femur rod and said tibia rod, and medication adhered to the femur and tibia rods for engagement with the medullary surfaces..
