Rationale: It is challenging to visualize and reduce a posterolateral tibial plateau fracture through an anterolateral approach as the tibial plateau fragments are often covered by the fibular head and ligamentous structures.
Patient concerns: In this case report, we describe a patient with a depression fracture of the posterolateral quadrant combined with a split fracture of the posteromedial quadrant and an avulsion fracture of the tibial intercondylar eminence.
Diagnoses: Tibial plateau fracture(AO type 41-B3).
Interventions: A posteromedial approach combined with an anterolateral approach and an osteotomy involving the proximal tibiofibular joint of the tibial plateau was used to expose, reduce, and fix the fracture.
Outcomes: There was no risk of injury to the common peroneal nerve or ligaments. The patient is recovering well and is satisfied with the function of the injured knee.
Lessons: We recommend anterolateral tibial plateau osteotomy for the treatment of posterolateral tibial plateau fractures in clinical practice.
