Fig 1.
Pre-operative IJLCM technique.
Assessment of pre-operative joint line height calculated as the average value of the tibial height and femoral height on the least affected side. TibAx1 = the intramedullary axis of the tibia, PF1 = a line perpendicular to TibAx1 at the level of the most proximal point of the proximal fibula.

Post-operative IJLCM technique.
Assessment of post-operative joint line height calculated as the average value of the Lateral Femoral Condyle (LFC) Height and the Medial Femoral Condyle (MFC) Height.
