Lateral epicondylitis of the elbow

Lateral epicondylitis, also known as 'tennis elbow', is a very common condition affecting mainly middle-aged patients. The pathogenesis remains unknown but there appears to be a combination of local tendon pathology, alteration in pain perception and motor impairment. The diagnosis is usually clinical but some patients may benefit from additional imaging for a specific differential diagnosis. The disease has a self-limiting course of between 12 and 18 months, but in some patients, symptoms can be persistent and refractory to treatment. Most patients are well-managed with non-operative treatment and activity modification. Many surgical techniques have been proposed for patients with refractory symptoms. New non-operative treatment alternatives with promising results have been developed in recent years.
