KNEE JOINT PROSTHESIS PAD, SHINBONE BASE ELEMENT, AND KNEE JOINT PROSTHESIS

摘要

A knee joint prosthesis, a knee joint prosthesis pad (3), and a shinbone base element (2). The knee joint shinbone base element is combined with a shinbone, and comprises a base (21), a boss (23) is arranged on the base (21), and a guide channel (25) through which an anterior cruciate ligament (4) passes is formed on the boss (23) and the base (21). The knee joint prosthesis pad (3) is provided with a pad opening (31') or a pad through hole (31) for accommodating the boss (23) of the shinbone base element (2). The knee joint prosthesis comprises the shinbone base element (2), the knee joint prosthesis pad (3) and a shinbone element (1) combined with the shinbone. The attaching position of the anterior cruciate ligament (4) relative to the shinbone base element (2) can be kept consistent with the attaching position of a human body anterior cruciate ligament in anatomy on the shinbone, so that the knee joint prosthesis can be used to rebuild an anterior cruciate ligament, and a patient regains the body feel and moves well after replacement of the knee joint prosthesis.
