PROBLEM TO BE SOLVED: To provide a jig for total knee replacement accurately determining a position and an angle of a distal bone cut surface using an intramedullary alignment rod by appropriately reflecting an individual difference of a patient, and then reproducing a content determined from a reference point of a femur knee joint using a dedicated jig to be mounted on the intramedullary alignment rod during operation.SOLUTION: The jig for total knee replacement includes: a contact part 31 coming into contact with a reference point of the knee joint of the femur mounting parts 33 and 34 for mounting an intramedullary alignment rod (IM) to be inserted into the marrow of the femur and an arm part 32 that connects the contact part 31 and the mounting parts and that can adjust the mounting position and mounting angle of the mounting parts 33 and 34 according to a parameter relating to the implantation of the intramedullary alignment rod (IM) that has been preoperatively determined.COPYRIGHT: (C)2015,JPO&INPIT【課題】患者の個人差を適正に反映して、髄内アライメントロッドを用いる遠位骨切り面の位置及び角度を正確に決定した上で、術中に上記髄内アライメントロッドに装着する専用の治具を用いて大腿骨膝関節の参照点から決定した内容を再現する。【解決手段】大腿骨の膝関節の参照点に当接する当接部31と、大腿骨の髄内に挿入する髄内アライメントロッド(IM)を装着する装着部33,34と、当接部31と装着部とを接続し、装着部33,34の取付け位置及び取付け角度を術前に決定した髄内アライメントロッド(IM)の刺入に関するパラメータに従って調整可能なアーム部32とを備える。【選択図】図10
