[Nonsurgical treatment of tennis elbow].

OBJECTIVE

To review the literature on nonsurgical treatment of tennis elbow.

METHODS

We searched Medline for all randomized controlled trials (RCTs), controlled clinical trials (CCTs) and literature reviews published from 1966 to December 2003 on nonsurgical treatment of tennis elbow. We used the keys words controlled clinical trial, tennis elbow on lateral epicondylitis, and treatment. We found 46 reports of RCTs and CCTs on 14 nonsurgical treatments and 11 literature reviews.

RESULTS

Corticosteroid injection is the best treatment option for the short term. However, beneficial effects persisted only for a short time, and the long-term outcome could be poor. For the long term, physiotherapy (pulsed ultrasound, deep friction massage and exercise programme) was the best option but was not significantly different from the "wait-and-see" approach. Some support is offered for the use of topical nonsteroid anti-inflammatory drugs, at least for the short term. There is insufficient evidence to support or refute the use of acupuncture, extracorporeal shock wave therapy, manipulation, orthoses, low-energy laser, glycosaminoglycan polysulfate injection, botulinum toxin injection, or topical nitric oxide application.

CONCLUSION

Further trials, with use of appropriate methods and adequate sample sizes, are needed before conclusions can be drawn about the effects of many of the treatments for tennis elbow and their ability to change the condition's natural course.
