Chronic ankle instability (CAI) is a condition in which an individual experiences recurrent ankle sprains or a feeling of giving way in the ankle joint. It is usually caused by an initial ankle injury or sprain that did not heal properly, resulting in ankle joint instability. The condition is most commonly seen in athletes who participate in sports that involve jumping, twisting, and turning, such as basketball, soccer, and volleyball. However, it can also affect individuals who are not involved in sports.
Symptoms of chronic ankle instability may include pain, swelling, and stiffness in the ankle joint, a feeling of giving way or instability in the ankle, and difficulty walking or participating in physical activities. Over time, repeated ankle injuries can lead to damage to the ankle joint and surrounding tissues, increasing the risk of developing osteoarthritis.
Treatment for chronic ankle instability may involve physical therapy to strengthen the muscles and improve ankle stability, wearing an ankle brace or taping the ankle to provide additional support, and in some cases, surgery to repair damaged ligaments or other tissues in the ankle joint. It is important to seek treatment for chronic ankle instability to prevent further damage and improve mobility and quality of life.
