Abstract

OBJECTIVE
To determine the effect of prolotherapy on lateral epicondylitis, and the difference of treatment effect according to the findings of ultrasonography. METHOD: The subjects were 84 patients who were diagnosed as lateral epicondylitis. The pain score was evaluated by using VAS (Visual Analogue Scale) before treatment and 1 month and 6 months after the 3rd injection. Ultrasonography was done to 49 patients who were suspicious of tendinous tear.
RESULTS
In the comparison of the VAS before treatment and after the 3rd injection, it was 6.79+/-0.88, 2.95+/-1.90, respectively, which demonstrated statistical significant decrease (p<0.01). We found more significant reduction of VAS in the subjects without tendinous tear (7.08+/-0.91 to 2.16+/-1.57) than those with partial tendinous tear (6.90+/-0.93 to 3.67+/-1.76) (p<0.01). Among 71 patients whose symptom was improved after the treatment, 57 patients (80.2%) demonstrated sustained improvement at 9 months and 14 patients (19.7%) relapsed at 9 months.
CONCLUSION
Prolotherapy is an effective treatment method in the lateral epicondylitis of elbow. Ultrasonography could be a useful diagnostic method which could predict the effect of prolotherapy.
