"Mechanical axis" refers to an axis of a long bone such as a femur or tibia. The mechanical axis of a long bone is a straight line connecting the joint center points of the proximal and distal joint regions, whether in the frontal or sagittal plane. A mechanical axis can be useful in defining how the mechanical (weight, gait, flexion, extension, etc.) forces impact the morphology of the bone structure. A mechanical axis and anatomical axis can both help in the surgical planning in relation to deformed bones.
