[Neuro-arthropathy, a painless but very destructive disorder of frequently one joint]

In a 38-year-old man who suffered from recurrent painless swelling of the right knee, neuroarthropathy was diagnosed, associated with tabes dorsalis. The patient was treated with a knee brace to stabilise the joint. Neuroarthropathy is a progressive degenerative joint disease caused by a central or a peripheral neurological disorder and causing denervation of the joint.
