Which type of epicondylitis is more common?

Lateral epicondylitis, often referred to as tennis elbow, is more common than medial epicondylitis, or golfer's elbow. This disparity is largely due to the variety of activities that contribute to overuse injuries of the lateral extensor tendons of the forearm. Lateral epicondylitis typically results from repetitive wrist extension or forearm supination, activities frequently encountered in sports as well as in various occupational tasks.

In contrast, medial epicondylitis involves pain on the inside of the elbow and is associated with different motions, such as those in golf or baseball; however, the incidence is notably lower. Understanding the underlying mechanisms of both conditions helps clarify why lateral epicondylitis is more commonly diagnosed in the general population. Proper assessment and treatment for either condition are crucial for effective recovery and returning to activity.
