A–F The five lower limb bony angles measured on anteroposterior and lateral radiographs. (A) mechanical axis angle (MAA) formed by intersection of the femoral and tibial mechanical axes. (B) anatomical axis angle (AAA) formed by the intersection of the femoral and tibial anatomical axes (C) medial tibial angle (MTA) formed by the tibial mechanical axis and the slope of medial tibial plateau. (D) posterior medial tibial angle (PMTA) created by the tibial anatomical axis and slope of the medial tibial plateau on a lateral film. (E) anatomic lateral femoral angle (ALFA) which is the lateral angle formed by the intersection of femoral anatomical axis and a line draw through the femoral condyle.
