Replacement knee joint comprises linkages forming deformable quadrilateral reproducing knee movement, linear transmission system and control module for modifying speed of flexion and extension movements

摘要

The replacement knee joint comprises:(a) a set of linkages forming a deformable quadrilateral and reproducing the natural movement of the knee, (b) a linear transmission system (8, 9) and (c) a control module (50) for modifying the speed of flexion and extension movements to suit the dynamics of the individual . The joint system is connected to the control unit by a rigid connection (56).
