Lateral epicondylitis

Purpose of review The present article reviews the most recent research into the anatomy, pathophysiology, and treatments, including nonsurgical and surgical options, of lateral epicondylitis. Recent findings Despite numerous studies of lateral epicondylitis, much regarding the pathophysiology and best treatment options remains uncertain. Recent research has improved understanding of the etiology of lateral epicondylitis, suggesting anatomic and vascular components of its development. Additionally, research in nonsurgical treatment has indicated that the short-term benefit of corticosteroids might be reversed in the long term, has suggested that physical therapy might be the best of the established options, and has presented several novel treatments. It is clear that all common surgical approaches yield good-to-excellent results, but it remains unclear which surgical treatment is best. Summary Lateral epicondylitis is a common cause of lateral elbow pain, first described more than 100 years ago. The condition has not been well characterized, although it has been frequently studied. Recent research has shed more light on the complex etiology of this disorder, which is helping to elucidate the best method of treatment.
