Modularized prosthesis leg cover

A modularized prosthesis leg cover, comprising:

• a thigh cover module mountable to a prosthesis leg at a position above a knee joint part, the thigh cover module forming a thigh shell for the prosthesis leg;
• a patella module forming a kneecap for the prosthesis leg;
• a lower leg cover module mountable to the prosthesis leg at a position below the knee joint part, the lower leg cover module forming a lower leg part for the prosthesis leg;
• a lower leg front pad and a lower leg rear pad mounted to the lower leg cover module, the lower leg front and rear pads forming a lower leg shell;
• and
• a skin module covering the thigh cover module, the patella module, the lower leg front pad, and the lower leg rear pad, wherein
• the thigh cover module, the patella module, and the lower leg cover module are separately assembled to each other,
• the prosthesis leg cover is a shell for covering the prosthesis leg, and
• the skin module is provided with a contractible reverse U-shaped knitted part at a position corresponding to the kneecap.
• wherein the patella module includes two protrusions formed on opposite sides of a rear part of the patella module, and grooves are formed between a lower round surface of the thigh cover module and an upper round surface of the lower leg cover module such that the protrusions of the patella module fit into respective ones of the grooves.
