Fracture simulation, reduction, and additional screw osteosynthesis. Workflow of specimen preparation for the fracture model: Five determined breaking points (a) for the indenter (b) were set on the lateral tibial plateau to produce a pure impression fracture (c). After placing a K-wire under the depressed fragment (d), the lateral corticalis was opened with a drill (e), enabling placement of a cannulated ram (f) to compact subchondral spongiosa and restore a plane joint surface (g). In groups 5–7, fracture stabilization was complemented with a four-screw osteosynthesis using the jail technique (h).
