An epidemiologic study of tennis elbow. Incidence, recurrence, and effectiveness of prevention strategies.

An epidemiologic study of the incidence and recurrence of tennis elbow among over 500 tennis players (278 men, 254 women; age range, 20 to 50 years) indicated that age and amount of playing time per day were contributing factors to the injury. Both incidence and recurrence rates increased with age. An interactive effect of playing time and age was observed with increased playing time associated with higher incidence at younger ages. Larger grip size was also associated with higher incidence in the older group. These findings were interpreted as being consistent with the hypothesis that tennis elbow is a degenerative disease, the onset of which is hastened by overuse of the arm and elbow. Changes in stroke technique and types of racket were successful in preventing recurrence. Least successful was the forearm brace.
