Lateral epicondylitis or tennis elbow is a painful overuse condition that affects the tendons on the lateral aspect of the elbow. It is a common injury for anyone that performs repetitive motions such as tennis players who often perform an excessive amount of wrist extension with backhand swings. Although this condition is most commonly referred to as tennis elbow, lateral epicondylitis has many different causes and may occur in any sport or activity that involves repetitively gripping an object.
