An object of the present disclosure is to provide a surgical instrument that can facilitate adjustment between a progressive position gap and a flexed position gap by additionally resecting a bone after resection of a femur distal portion. A surgical instrument () includes a body portion () including a first abutment surface () abuttable against a distal end resection surface () of a femur distal portion () and a posterior condyle abutment portion () including a second abutment surface () abuttable against a posterior condyle resection surface () of a posterior condyle portion () of a femur () and connected to the body portion (). The body portion () includes a first slit () extending in a direction parallel to the second abutment surface () and a second slit () extending in a direction intersecting the first abutment surface () and the second abutment surface ().

Surgical instrument

When using an artificial knee joint replacement operation instrument, the amount of labor required to attach a tibial insert trial to a patient is further reduced. An artificial knee joint replacement operation instrument has a tibial trial attachment instrument assembly used in an operation for replacing a patient's knee joint with an artificial knee joint. The tibial trial attachment instrument assembly includes a template to be attached to a tibia, a keel punch guide to be joined to the tibia via the template, a keel punch to be inserted into the tibia through the keel punch guide, a keel punch handle for operating the keel punch, and a tibial insert trial to be placed on the template, the tibial insert trial being separate from the template.
