Pre-contoured plates attempt to match the bony anatomy of the target patient population. However, plate fit is highly variable due to inter-subject morphological differences. If plate misfit is not recognised and addressed, axial malalignment may arise. This study evaluates the effects of age, sex, height, ethnicity, and femoral bowing on the anatomical fit of a distal femur plate.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Unilateral 3D models of 80 (40 male, 40 female) Caucasian and 79 (34 male, 45 female) Vietnamese femora were utilised. Both cohorts consisted of young (&lt;\u200965 years) and old (\u2265\u200965 years) subjects, with 40 young and 40 old Caucasian, and 36 young and 43 old Vietnamese.

There was tendency towards proximal plate misfit from hole 8 onwards with 0\u201341% fit achieved in this region, and mean distances of 11.6\u00a0mm and 16.3\u00a0mm being observed at the proximal plate tip for Caucasians and Vietnamese respectively (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009\u2264\u20090.017).
