Charcot joint is best described as joint damage resulting from what mechanism?

• A. Infection-related joint destruction.
• B. Autoimmune arthritis with symmetric involvement.
• C. Peripheral neuropathy causing repetitive microtrauma leading to joint damage.
• D. Osteoarthritis due to aging.

Answer: (C)

Charcot joint is a neuroarthropathy caused by peripheral neuropathy that blunts protective sensation and proprioception. When you lose normal feeling in a joint, small injuries from daily use go unnoticed and accumulate, so repetitive microtrauma weakens bone and cartilage, loosens ligaments, and leads to fragmentation, collapse, and deformity of the joint. This destructive process happens with little inflammatory response, which helps distinguish it from infectious arthritis or autoimmune inflammatory diseases. It’s most often seen in the foot or ankle of people with diabetic or other neuropathies, whereas infections cause systemic signs, autoimmune arthritis tends to be symmetric and inflammatory, and osteoarthritis is a degenerative process driven by wear and aging rather than neuropathy.
