What is Ankle Arthritis?

Ankle arthritis is a clinical condition in which the joint that connects the foot to the leg, known as the tibiotalar or ankle joint, has damaged or worn out cartilage. There are three bones involved in this joint: the tibia, the fibula and the talus. The arthritis can involve any or all of these bones.

Causes

Ankle arthritis may occur as a result of wear and tear, injury or be part of a more widespread arthritis.

Symptoms

Pain and swelling are the key warning signs of ankle arthritis.

Diagnosis

Ankle arthritis is diagnosed by a combination of the symptoms, physical examination and x-rays or other imaging tests.

X-rays are commonly employed to diagnose ankle arthritis. Other tests might be used such as MRI or CT scan for unusual conditions. When ankle arthritis is a part of a systemic condition, blood tests may be used for its diagnosis. Occasionally, a bone scan may be useful. Other tests involving injection of solutions into joints may be employed at times.
