Stress fractures of the tibia secondary to tibial deformities from osteoarthritis are rare, and may be difficult to manage. We treated two patients with stress fractures of the proximal tibial diaphyses over a period of two years. Both patients had osteoarthritis of the knee; one with genu valgus deformity and the other, genu varus deformity. The former patient also had a distal tibial fracture and had previously undergone open reduction and internal fixation. The stress fractures of both the patients had been treated conservatively by nonoperative means, but their fractures failed to unite. They then underwent a modular total knee prosthesis with a long tibial stem extension, and subsequently, their fractures united. Both patients recovered uneventfully.
