What is Hindfoot arthritis and deformity?
Hindfoot arthritis involves pain and stiffness in the joints at the rear of the foot. These joints are made up of the heel bone (calcaneum) and the ankle bone (talus). Hindfoot arthritis is a condition where the cartilage surfaces that line the joints become thin and eventually wear out completely. Joints are surrounded by the synovium, which produces a fluid that lubricates the cartilage and reduces friction during movement. When this cartilage and lubrication are no longer present, it can cause bone on bone rubbing, resulting in deformity, pain, and discomfort. Usually, hindfoot arthritis and related deformity occurs slowly over a period of years.
