Arthritis is a chronic medical condition that affects the joints of the body. It is characterized by inflammation in the joint resulting from the degeneration of cartilage, which is the tissue that cushions the joints. When this tissue wears away, the bones in the joint can rub against each other, causing pain, swelling, and stiffness. Arthritis can occur in any joint in the body, including the foot and ankle joint.
Arthritis of the foot and ankle joint can occur due to a variety of reasons, including fractures, dislocation, inflammatory disease, or congenital deformity. The most common types of arthritis that affect the foot and ankle joint are osteoarthritis, rheumatoid arthritis, and post-traumatic arthritis.
The foot joints most commonly affected by arthritis are:
- The joint between the shinbone (tibia) and ankle bone (talus): This joint is responsible for the up-and-down motion of the foot. When it is affected by arthritis, it can cause pain and stiffness, making it difficult to walk or stand for long periods of time.
- The three joints of the mid-foot that include the heel bone, the inner mid-foot bone, and the outer mid-foot bone: These joints are responsible for the side-to-side motion of the foot. When they are affected by arthritis, it can cause pain and swelling, making it difficult to wear shoes or walk on uneven surfaces.
- The joint of the great toe and foot bone: This joint is responsible for the up-and-down motion of the big toe. When it is affected by arthritis, it can cause pain and stiffness, making it difficult to walk or stand for long periods of time.
It is important to note that arthritis is a chronic condition that can worsen over time if left untreated. However, with proper treatment, including medication, physical therapy, and lifestyle modifications, it is possible to manage the symptoms of arthritis and improve overall quality of life.
