We are looking for distibutors to sign exclusive rights contract. KTJ - Top Knee Joint is a mechanical system. A variable center of rotation, which recreates the roto-translational motion of the knee. In its motion of flexion, the knee for the first 30 ° has a rolling motion, after the 30 ° becomes roto-translational motion.At this stage, the sliding of the femur on the tibia becomes more predominant and the center "snapshot" of rotation tends increasingly to approach the articular surfaces. Innovation KTJ calculates at each stage of flexion the position of the instantaneous center of rotation. So we produce knee braces with a new intenational patented ( in Europe, Japan, Usa, Canada, Australia) joint, made to keep knees safe. A new way to prevent injuries without any pain for legaments. we tested and compared it with other manifacturers products, but no one could compete with our new medical miracle!!! We are the innovation itself!
