Abstract
Charcot neuroarthropathy is a bone and joint disorder in patients with diabetic neuropathy, which typically affects the bones and the joints of the forefoot, midfoot and ankle. Diabetic neuropathy may be the main cause of the pathologic bone metabolism and can lead to the fracture in any region of skeleton (e. g. shoulder, elbow joint, spine, hip and knee).
Neuropathic fracture is the typical example of pathologic fracture, which is defined as a fracture appeared without trauma in history. Well-timed and correct diagnosis is necessary for successful therapy, which is more difficult and longer than in patients with usual fractures. Neuropathic fractures require together with fixation also long-term off-loading and metabolic control, recalcification therapy and appropriate treatment of infection. We describe rare cases of neuropathic fractures in patients with diabetes in atypical localization - in the knee-joint.
