Abstract
Severe valgus deformity of the knee secondary to osteoarthritis can predispose to stress fracture of the lateral tibial plateau. Described herein is a case of severe valgus knee deformity that was complicated by an intra-articular tibial plateau stress fracture and treated by a fully constrained Guepar hinge prosthesis with a satisfactory end result. The etiology and mechanism of this complication are discussed, with emphasis on the diagnostic process.
