Osteoarthritis is a degenerative disease affecting joints. Joints are cushioned by cartilage located at the ends of the bones, forming a protective barrier between the bones, allowing them to glide over, rather than rub against, each other. Osteoarthritis occurs when this cartilage wears down due to overuse or injury, causing inflammation and pain.
Osteoarthritis in the foot occurs most commonly in the joint between the big toe and its long bone, termed the first metatarsophalangeal joint. The ankle, the hindfoot, and the midfoot are also commonly affected.
Various factors can contribute to the development of osteoarthritis. These include injury, overuse, anatomical anomalies, biomechanical problems, flat feet, or high arches.
