Ankle arthritis is a condition in which the cartilage of the ankle joint deteriorates, causing pain and restricting movement. Progressive arthritis can lead to bone cysts and the formation of bone spurs (osteophytes). When conservative therapies - such as ankle braces, cushioned insoles, anti-inflammatory drugs, cortisone injections, and physical therapy - fail to provide relief, surgery may be considered if the pain and loss of mobility seriously impair your quality of life.
