[Evidence-based evaluation of present guidelines for the treatment of tennis elbow -- a review].
The guidelines of the German Orthopaedic Societies regarding the treatment of lateral elbow epicondylitis were analysed on the ground of recently published reviews or randomised placebo-controlled trials (RCT). For the acute phase, reviews or RCTs failed to show a clinical effect beyond placebo if follow-up was extended over 6 weeks. For the chronic phase a current Cochrane review failed to identify any controlled trial regarding surgical procedures during the last decades. Without an adequate control group, it is not possible to draw any meaningful conclusions about the value of this modality of treatment. Therefore surgery is not indicated before repetitive low-energy extracorporeal shock wave therapy (ESWT) has been applied. This novel treatment, under strictly standardized conditions, showed effects beyond placebo in independent randomised placebo-controlled trials for follow-up periods of 3 and 6 months. To date there exists no evidence-based therapeutic algorithm for the treatment of acute and chronic tennis elbow. Even medium-term effects should be regarded as either a placebo effect or natural regression to the mean.
