Publisher's Synopsis
The work describes the implementation of "joint with variable center of rotation" as a mechanical organ that mimics the physiological roto-translational motion of the knee and is applicable to orthopedic devices addressed to knee physical therapy.The results recorded so far enable us to state that the KTJ devices create favorable conditions not only for the recovery of walking (braces), especially in elderly with degenerative diseases, but also in reducing recovery times postoperatively ( applying on the machines for passive gymnastics).The results of the studies done, may also be considered as a response to what Insall (86) wrote about the "Lack of significance of studies on the knee kinematics based on anatomical location of the instantaneous center of rotation".
