Probability of Developing Tennis Elbow

Tennis elbow (lateral epicondylitis) affects approximately 1-3% of the general population each year, with peak incidence between ages 30 and 50. Despite its name, only about 5% of cases are actually related to playing tennis. The condition is caused by overuse and repetitive stress on the forearm muscles and tendons.

Occupations with the highest risk include plumbers, painters, carpenters, butchers, and auto mechanics. Computer use, particularly with poor ergonomic setup, has also been associated with increased risk. The dominant arm is affected about 75% of the time, and the condition is equally common in men and women.

Most cases (80-90%) resolve within 6-12 months with conservative treatment including rest, ice, physical therapy, and anti-inflammatory medications. Counterforce bracing and eccentric exercises are particularly effective. For persistent cases, treatments include corticosteroid injections (though these provide only short-term relief), platelet-rich plasma (PRP) injections, and in rare cases, surgery. Recurrence rates are about 8-15%.
