Lateral epicondylitis(LE)is a chronic aseptic inflammatory condition caused by repetitive microtrauma and excessive overload of the extensor carpi radialis brevis muscle.This is the most common cause of musculoskeletal pain syndrome in the elbow,inducing significant pain and limitation of the function of the upper limb.It affects approximately 1-3%of the population and is frequently seen in racquet sports and sports associated with functional overload of the elbow,such as tennis,squash,gymnastics,acrobatics,fitness,and weight lifting.Typewriters,artists,musicians,electricians,mechanics,and other professions requiring frequent repetitive movements in the elbow and wrists are also affected.LE is a leading causation for absence from work and lower sport results in athletes.The treatment includes a variety of conservative measures,but if those fail,surgery is indicated.This review summarizes the knowledge about this disease,focusing on risk factors,expected course,prognosis,and conservative and surgical treatment approaches.
