A tibial resection assisting device includes: a femoral paddle including a first contact surface brought into contact with a resection surface of a distal portion of a femur; and a tibial paddle including a second contact surface brought into contact with a proximal portion of a tibia that is unresected. The femoral paddle is mounted to a base disposed at an anterior side of a knee joint. A movable body mounted to the base is movable in an orthogonal direction to the first contact surface. The tibial paddle is mounted to the movable body and is swingable about a swing shaft that extends in an anterior-posterior direction of the knee joint, the anterior-posterior direction being parallel to the first contact surface. Further, a reference guide mounted to the base is movable in the orthogonal direction and is intended for positioning a tibial cutting guide.
