Factors that increase your risk of a sprained ankle include:

  • Sports participation. Ankle sprains are a common sports injury. Sports that require rolling or twisting your foot, such as basketball, tennis, football, soccer and trail running, can make you vulnerable to spraining your ankle, particularly if you're overweight. Playing sports on an uneven surface also can increase your risk.
  • Prior ankle injury. Once you've sprained your ankle, or had another type of ankle injury, you're more likely to sprain it again.
