Aim: To evaluate whether patients with lateral epicondylalgia had less pain or function loss two years following treatment by a structured programme and if the number of recurrent episodes and sick leave days differed compared with a control group. Subjects: All of the patients were diagnosed by a physician with the diagnosis code M77.1 (lateral epicondylitis). The intervention group (n = 103) was treated by a physiotherapist and an occupational therapist with a home training programme that included ergonomic advice. Wrist supports and/or night bandages were also available. Controls (n = 194) were diversely treated by different professionals. Major findings: In the total study group (n = 297), 54% of the patients experienced pain and 55% experienced function loss after two years. The intervention group had less pain than patients treated with corticosteroid injections (p < 0.0001) or NSAIDs (p = 0.048) and experienced better function than those treated with corticosteroid injections (p = 0.002). The intervention group had a lower recurrence (p < 0.0001) and fewer sick leave days at the time of the visit to the health care centre (p = 0.005). Principal conclusions: A structured treatment programme was more effective than corticosteroid injections and NSAIDs. Patients did not require additional treatment or sick leave and had learned self-treatment of the disorder.
