Fig. 3From: A lower starting point for the medial cut increases the posterior slope in opening-wedge high tibial osteotomy: a cadaveric studyAnteromedial view of the right knee, 4 cm case. The placement of the opening wedge in the M third of the tibia generates a parallel gap (a). In contrast, when the wedge is located in the PM third of the tibia, the result is an asymmetric gap. The extent to which the medial collateral ligament (MCL) may hinder the posterior placement of the opening wedge is also shown (b).
