Sports injuries are injuries that occur in athletic activities. In many cases, these injuries are due to overuse or acute trauma of a part of the body when participating in a certain activity. For example, runner’s knee is a painful condition generally associated with running, while tennis elbow is a form of repetitive stress injury at the elbow. Other types of injuries can be caused by a hard contact with something. This can often cause a broken bone or torn ligament or tendon. The most severe injuries and all fatalities are collectively known as catastrophic injuries, usually a result of trauma to the head, spine, or spinal cord.

Injuries are a common occurrence in professional sports and most teams have a staff of Athletic Trainers and close connections to the medical community.
