Shortcomings of tennis elbow treatment have raised medical interest in pathomechanics of this condition. In 2009, a new theoretic model was proposed, one that has integrated the current knowledge about tennis elbow pathophysiology, with aim to improve the effectiveness of therapeutic methods. It was suggested that tennis elbow patients should be grouped by severity of local tendon pathology, change in pain perception and degree of motor apparatus malfunction when deciding on the most suitable treatment method or when designing scientific research on the subject. It is believed that by employing detailed diagnostics of these lesions (either separate or clustered) in order to confirm or eliminate their presence, the effectiveness of their treatment should increase.
