Epicondylitis of the elbow is a common cause of elbow pain, with lateral epicondylitis occurring more frequently than medial epicondylitis. Both lateral and medial epicondylitis are thought to arise from repetitive overuse of the elbow due to occupational or recreational activities, resulting in an insidious onset of pain around the lateral or medial epicondyle. This pain usually is worsened with grip, lifting, resisted wrist extension in lateral epicondylitis, and wrist flexion in its medial counterpart. MRI can provide valuable information about concomitant pathology but may not be predictive of epicondylitis symptomology. Conservative management is successful in the majority of cases and includes periods of rest, ice, physical therapy, activity modification, anti-inflammatory medication, injections (including corticosteroid, platelet-rich plasma, and botulinum toxin), and counterforce bracing. Surgical intervention, through an open or arthroscopic approach, may be necessary in recalcitrant cases. While both open and arthroscopic surgical approaches are well established and provide excellent outcomes with decreased pain and improved function, arthroscopic management offers additional advantages. Such benefits of arthroscopic treatment include lower surgical site infection rates and the potential for a quicker return to work and recreational activities.KeywordsEpicondylitisMedialLateralArthroscopicTendinosisTennisGolfersElbow
