Fig. 2A–C.

Tibial resection and measurements using the 3-D preoperative planning software are shown. (A) The proximal tibia was resected 9 mm below the lateral tibial plateau with a 3° posterior slope. (B) An axial MPR image of the resected surface is depicted. (C) A coronal MPR image of the resected tibia is shown. Half of the ML dimension is measured as the length from the lateral edge of the resected surface to the TSA. The middle AP (mAP) dimension is the length of the line segment passing through the TSA. Arrowheads indicate the medial edge of the tibial condyle to be resected. M = medial; L = lateral.
