Ankle sprain

An ankle sprain, commonly known as "twisted ankle," refers to an injury to the soft tissues surrounding the ankle joint, such as ligaments, tendons, and joint capsules, caused by the ankle joint moving beyond its normal range of motion (excessive inversion or eversion) during walking or exercise. Based on the degree of ligament damage, sprains can be classified into three grades: Grade I sprain: The ligament is stretched but not torn, and the ankle joint is relatively stable. Grade II sprain: The ligament is partially torn, resulting in varying degrees of ankle joint instability. Grade III sprain: One or more ligaments are completely torn, which may lead to fractures of surrounding bony structures and ankle joint instability.
