Using curve-fitting and the symmetric axis technique, the true anatomical axis was identified for each tibia. Regression lines were calculated for the distal 67% and distal 50% subsections of this axis. Angular deviations between these lines and DAA approximations were calculated and compared with to find the closest approximations.RESULTS:  The DAA approximations based on the distal 50% rather than the distal 67% of the tibia had smaller maximal deviations from the true axis. Landmarks at 50% and 75% of tibial length exhibited greater deviations than those at 50% and 95% or 100%.CONCLUSION:  The DAA landmarks should be restricted to the distal half of the tibia. Use of a distal landmark either just proximal to the distal metaphyseal flare of the tibia or at the mid-point of the distal articular surface is to be preferred.
