Tibial plateau fracture following oblique osteotomy of the tibial tubercle: a case report

Abstract

Oblique osteotomy of the tibial tubercle is a preferred technique in patellofemoral disorders, resulting in a satisfactory clinical outcome. However, postoperative fractures of the proximal metaphysis of the tibia may often develop. An incomplete fracture of the lateral tibial plateau occurred in a 23-year-old female patient following an oblique osteotomy of the tibial tubercle. There was no history of trauma. The patient had undergone two operations in the same knee due to patellar instability. She also had bilateral high congenital hip dislocation. The correct diagnosis could only be made by computed tomography. Complete union was obtained following six weeks of plaster cast fixation. Due to inherent biomechanical limitations, complications may arise following oblique osteotomy of the tibial tubercle even adequate care is given to the surgical technique.
