What is Ankle arthritis?
There are many bones and joints that make up the ankle. In many of these joints the ends of the bones are covered with articular cartilage that helps the bones glide smoothly during movement. Joints are surrounded by the synovium, which produces a fluid that lubricates the cartilage and reduces friction.
Ankle arthritis is a condition where the cartilage surfaces that line the ankle joint become thin and eventually wear out completely. Usually, ankle arthritis occurs slowly over a period of years. Narrowing of the ankle joint spaces, in particular between the tibia and the talus bones can be very debilitating and painful.
