Back to basics: Understanding charcot neuroarthropathy

‘Active’ Charcot neuroarthropathy (CN) is characterised by non-infectious inflammation in the presence of peripheral neuropathy (van Netten et al, 2019). The area of the foot most commonly affected is the mid-foot and this is associated with classic ‘rocker-bottom foot’ deformity (Botek et al, 2010; Mumoli et al, 2012; Dissanayake et al, 2012). While this condition is frequently associated with deformity, this may be prevented if caught early. Without timely recognition and offloading of the affected limb, progressive bone and joint destruction may, however, lead to significant deformity, ulceration, amputation and a vastly reduced quality of life (Caputo et al, 1998; Cates et al, 2019).
