Table 4 Static tests summary: Displacements, valgus-malrotation of the tibial head and their corresponding crack and ultimate loads, including mean values and standard deviations (SD)

From: Static and fatigue strength of a novel anatomically contoured implant compared to five current open-wedge high tibial osteotomy plates
