Fig. 1From: Autogenous structural bone graft reconstruction of ≥ 10-mm-deep uncontained medial proximal tibial defects in primary total knee arthroplastyKnee plain X-ray AP view showing measurement of the medial tibial defect. Line A is through the anatomical axis of the tibia. Line B passes through the deepest point of the defect and is perpendicular to line A. Line C passes through the highest point of the head fibula and is perpendicular to line A, representing the expected resection line of the tibial plateau. The red line is the size of the defectBack to article page
