I have heard that a sprained ankle can cause arthritis. Is that true?

Yes, it is true. A sprained ankle can cause arthritis in the joint. Sprained ankles are often caused by twisting motions or sudden changes in direction, which can lead to damage to the ligaments and tendons around the ankle joint. This damage can cause inflammation and swelling, leading to pain and stiffness in the joint. Over time, this inflammation and swelling can cause permanent damage to the joint, resulting in arthritis.
