Tennis elbow is a condition that affects a group of muscles and tendons in your forearm that attach to the bone on the outside of your elbow. It is also called lateral epicondylitis or lateral epicondylopathy. The extensor carpi radials brevis muscle is a specific forearm muscle affected by tennis elbow that helps to stabilize and move the wrist, but when injured from overuse it results in pain and weakness.

This condition is most well known for affecting tennis players but it can affect people who are active in many different activities, including racket sports, throwing sports, weightlifting, and others. This condition more commonly affects adults performing these repetitive activities without proper training. In order to prevent this, it is recommended you ensure proper fit and technique when using sports equipment. Stretching, strengthening, and progressive build-up of activities can also help decrease risk of developing tennis elbow. If you do suspect you have tennis elbow, using a sports medicine team to properly diagnose and treat this can get you back in the swing of things in no time.
