ICD-10: M14.6

Charcot's joint, clinically referred to as Charcot joint disease or neuropathic arthropathy, is a degenerative condition characterized by the progressive destruction of a joint due to loss of sensation and proprioception. This condition is often associated with diabetes mellitus, but it can also occur in other conditions that lead to neuropathy, such as syphilis, leprosy, or spinal cord injuries.

Clinical Description

Pathophysiology

Charcot's joint results from a combination of factors, including:
- Loss of Sensation: Patients with neuropathy experience diminished or absent pain sensation in the affected joint, which leads to unrecognized trauma.
- Repetitive Trauma: The lack of protective pain responses allows for repeated microtrauma to the joint, resulting in inflammation and subsequent joint destruction.
- Inflammatory Response: The body’s inflammatory response to the trauma can lead to bone resorption and joint dislocation.

Symptoms

Patients with Charcot's joint may present with:
- Swelling: The affected joint often appears swollen and may be warm to the touch.
- Deformity: As the condition progresses, joint deformities can develop, leading to significant functional impairment.
- Instability: The joint may become unstable due to the destruction of supporting structures.

Commonly Affected Joints

While Charcot's joint can affect any joint, it most commonly occurs in:
- The foot and ankle
- The knee
- The hip
