Tennis Elbow (Lateral Epicondylitis) is a common condition caused by overuse of the forearm muscles. The condition acquired its moniker because of its prevalence among the tennis community. In fact, as many as 50 percent of tennis players develop tennis elbow at some point in their careers. However, those diagnoses represent only 5 percent of all cases of tennis elbow.
Repetitive motions or injuries can cause tears in the muscles and tendons surrounding the outside of the elbow (the epicondyle). For athletes, this can interfere with performance, such as when swaying a bowling ball, swinging a golf club, or performing a backswing in tennis.
