Since the earliest prostheses, reproducing the complexity of human knees is a major challenge. In the 1990's, the first knee using a computer chip to control the swing was introduced; the microprocessor controls the speed and ease of the swing of the knee and the stability of the knee joint at rest. The sensor provides input to the knee prosthesis so that it can know at what stage of walking it is in the gait and can adapt to different circumstances. Bartlett Tendon Universal Knee is designed for extreme sports such as skiing and mountain biking downhill. Knee was invented by a professional skier, Brian Bartlett. Bartlett will use this foot to participate in a mountain bike race with a strong person - and often win
In a human joint, the knee is most susceptible to injury. In addition to the fact that this joint is heavy weighted, and in addition to the fact that it is designed for most human activities, knee joints are also the most common cause of joint injury. The two main movements are not only small turning and lateral movement, but also bending and stretching. "M. Mullin and K. Stone) There are basically five main parts in the knee," It is for this design that knee is easy to hurt. " Bone, muscle, ligament, cartilage, tendon. The function of the bone is to support the knee and make the joint hard. There are four bones in the knee. The first bone is the femur, also called the femur or femur. (University of Utah, Heath Science Center, 2003) This large bone is attached to another bone of the tibia via the ligament and the pouch. The humerus is the bigger bone of the knee called the tibia.
