Abstract

Foot involvement is not uncommon and occurs early in the disease course of rheumatoid arthritis (RA). Inflammation and ongoing synovitis of foot joints lead to joint destruction and instability, tendon dysfunction, and eventually collapse of the medial longitudinal arch and pes planovalgus that contributes to difficulty in walking and gait abnormalities. This article reviews foot-related problems in patients with RA, focusing on the prevalence, natural history and role of imaging in both diagnosis and management of midfoot and subtalar joint disease in RA.
