Knee joint for prosthetic leg

Abstract

A prosthetic knee unit useful with a prosthetic leg. The prosthetic knee unit includes a linkage assembly, at least one motor module, and a controller. The linkage assembly includes a base, a driven shaft at least one link, and an output body. The motor module is operably connected to the driven shaft. The controller is programmed to prompt operation of the at least one motor module. Operation of the at least one motor module, as prompted by the controller, articulates the output body relative to the base via pivoting movement of the at least one link. In some embodiments, the prosthetic knee unit further includes at least one sensor, such as an IMU worn by the user. With these and related embodiments, the controller is programmed to receive sensed information from the sensor and to control operation of the at least one motor module based upon the sensed information.
