Neuropathic arthropathy (or neuropathic osteoarthropathy), also known as Charcot joint (often "Charcot foot"), refers to progressive degeneration of a weight bearing joint, a process marked by bony destruction, bone resorption, and eventual deformity. Onset is usually insidious. If this pathological process continues unchecked, it could result in joint deformity, ulceration and/or superinfection, loss of function, and in the worst case scenario: amputation or death. Early identification of joint changes is the best way to limit morbidity.
