Much has been written about lateral epicondylitis/tennis elbow reflecting the existence of many treatments for the condition. However, there is no consensus as to which treatment gives the best results.

Based on the latest meta-studies and reviews from the Cochrane Library, one may conclude that there is evidence of a short-term effect of topical or per oral NSAIDs. The same is true for manipulation and exercise. Corticosteroid injection has also been shown to have short-term effect, but not beyond 6 weeks. Ultrasound has a possible short-term effect based on one meta-analysis. Extra corporeal shock wave therapy does not seem to be effective. The treatment with acupuncture, orthosis, surgery or long-term NSAIDs has no support in the literature, and it is impossible to draw any conclusions about the effects or absence thereof. In fact, there is scant support for any long-term treatment in the literature.

We have found two studies to be of special interest (see citations below). Both have been done in a primary care setting with one-year follow up. One study compares corticosteroid injection with physical therapy (ultrasound, manipulation and exercise) and a wait-and-see group. The other compares corticosteroid injection with naproxen orally and placebo-medication. Both conclude that corticosteroid injection is a safe and effective treatment as pain-relief during the first 6 weeks, and that the effect of this treatment is better than physical therapy, wait-and-see and naproxen orally within the same time-frame. Physical therapy in one study gives some, but not statistically significantly better long-term (one year) effect than wait-and-see treatment.

There seems to be some indication that corticosteroid injection is a good alternative for the first 6 weeks. We find there is a good reason to investigate the long-term effects of physical therapy. At the same time, it would be interesting to see whether the good initial response from corticosteroid injection may be extended if combined with physiotherapy.

This randomised, placebo-controlled study will be conducted in general practice in Ostfold County, Norway including patient aged 18-70 years with pain of recent onset from the lateral part of the elbow. After a treatment-period of 6 weeks, the patient is followed for a total of 12 months.

Patients are recruited by interested general practitioners in the city of Sarpsborg and surroundings and remitted to two study-physicians who make the initial evaluation of inclusion- and exclusion criteria, as well as treatment, follow-up and outcome assessments during the whole study-period. The patients are treated by one of the two study-physicians in the 6-weeks treatment-period. From the 6. week, the patient sees the other physician, who is unaware of the allocated intervention, for further registration and assessment.
