Abstract

Abstract : Charcot knee is a rare condition with few reported cases in the literature. Although the clinical presentation is highly variable, Charcot knee classically presents with painful arthropathy in addition to instability and decreased range of motion. Herein, we describe the case of a 72-year-old man with idiopathic Charcot knee. The diagnosis was established on the basis of history of neuropathic arthropathy of the knee, supported by knee radiographs and the exclusion of all known etiologies of Charcot knee. Because of a highly destructed knee joint, the patient underwent a total knee arthroplasty using the Global Modular Replacement System proximal tibial prosthesis. The surgery was done without any major complications, resulting in symptomatic and functional improvements.
