Fig. 3From: The 3-triangle method preserves the posterior tibial slope during high tibial valgus osteotomy: first preliminary data using a mathematical modelLinear regression analysis showed a statistically significant correlation of the postoperative medial proximal tibial angle (MPTA) and the postoperative location of the WBL on the tibial plateau width ratio. An increase of the MPTA by one degree will lead to lateral shift of the WBL by 3.2% along the coronal tibial plateau widthBack to article page
