Patent number: 10639162Abstract: The present invention provides an artificial knee joint that can reconstruct an anterior cruciate ligament in a state close to an original function. An artificial knee joint (1) that is used in a total knee replacement includes a femur member (10) and a tibia member (20). The tibia member (20) has a ligament insertion hole (20h) which pierces the tibia member (20) and which is formed at a position where once an anterior cruciate ligament (ACL) exists in a knee replaced for the artificial knee joint (1). Therefore, a ligament can be provided such that a distal end (DT) of a femur (F) and a proximal end (PE) of a tibia (T) are joined to each other by passing the ligament through the ligament insertion hole (20h), which allows the anterior cruciate ligament (ACL) to be reconstructed so as to be in the substantially same state as a knee replaced for the artificial knee joint (1).Type: GrantFiled: June 24, 2015Date of Patent: May 5, 2020Assignee: NATIONAL UNIVERSITY CORPORATION EHIME UNIVERSITYInventors: Hiromasa Miura, Kazunori Hino
