Causes

Tennis elbow is mostly due to repetitive use of those movements that are commonly executed in playing tennis. It has an incidence of 50% in tennis players and occurs more frequently in individuals between 40-50 years of age. Lateral epicondylitis can also develop in other activities involving the frequent use of the elbows and wrists such as labourers (plumbers, painters, gardeners and carpenters) and computer users due to improper use of the keyboard.
