A modularized prosthesis leg cover quickly covers a prosthesis leg and does not affect bending or stretching motion of a knee joint part of the prosthesis leg, thus preventing damage to the knee joint part of the prosthesis leg. Thus, the modularized prosthesis leg cover includes a thigh module, which can be mounted to a thigh socket of the prosthesis leg, a lower leg module, which can be fastened to a calf pipe of the prosthesis leg, and a patella module, which can be rotatably assembled with the lower leg module. The prosthesis leg cover, which is formed by assembling the modules, is covered with a skin module, which is made of a stretchable fiber. The respective modules are provided as prefabricated modules. A method of manufacturing the prosthesis leg cover is also provided.

A knee joint structure has a five-joint link structure in which there are an upper link to which a thigh support part of an artificial limb is fixed; a lower link with which a foot part of the artificial limb is linked; a rear link for linking the upper and lower links and with each other; a main frontal link linked with the frontal of the upper link ; and an auxiliary frontal link for linking the main frontal link and the lower link with each other. In addition, there is provided an elastic element acting to increase an angle formed by the auxiliary frontal link and the lower link
