Abstract
A femoral sizing jig for use in total arthroplasty of left and right knees, comprises a femoral body, an external-rotation-angle arm which is, preferably pivotable, relative to the femoral body for setting an external angular rotation of a left or right femur, at least one of a cutting-jig guide and a cutting jig which is, preferably slidable, relative to the femoral body and in unison with movement of the external rotation-angle arm, and a medial posterior-condylar locator which is movable in unison with the movement of the external-rotation-angle arm, so as to maintain a fixed or substantially fixed relative distance with a medial side of the at least one of a cutting-jig guide and a cutting jig. A posterior-referencing femur resecting system using said femoral sizing jig and a method of resecting a femur at a knee joint relative to the medial posterior condyle are also provided.
