Background: The majority of all tibial plateau fractures (TPF), in detail the 86%, involves a flexion valgus type mechanism leading to fracturing of the postero-latero-central (PLC) region of the tibial plateau. Surgical treatment of this region is technically demanding due to the restricted field of view and area of access: an incorrect surgical management can entail articular incongruity, residual or even secondary depression after the surgical treatment. For this reason, it is occasionally chosen to leave PLC TPF untreated in case of a limited depression. The aim of the study is therefore to numerically check to what extent this choice is justified without clinical consequences (i.e.
