Abstract OBJECTIVE: We aimed to compare the efficacy of two different injection techniques of local corticosteroid and local anesthetic in the management of lateral epicondylitis. METHODS: This prospective study followed 80 consecutive patients who were diagnosed with lateral epicondylitis at our hospital outpatient clinic between 2005 and 2006. Patients were randomly assigned into two equal groups. Group 1 received a single injection of 1 ml betamethasone and 1 ml prilocaine on the lateral epicondyle at the point of maximum tenderness. Group 2 patients received an injection of the same drug mixture. Following the initial injection, the needle tip was redirected and reinserted down the bone approximately 30 to 40 times without emerging from the skin, creating a hematoma. Patients were evaluated with the Turkish version of the Disabilities of the Arm, Shoulder and Hand questionnaire before injection and at the final follow-up. The unpaired t-test and chi-square tests were used to compare results. RESULTS: Sixteen patients in Group 1 and 15 patients in Group 2 were lost during follow-up. The average follow-up period of the remaining 49 patients was 21.6 months. There were no significant differences between the two groups with regard to gender, age, follow-up period, symptom duration, involvement side and number of dominant limbs. The Turkish DASH scores of Group 2 were significantly lower than those of Group 1 (p=0.017). CONCLUSION: Long-term clinical success in the treatment of lateral epicondylitis depends on the injection method. The peppering technique appears to be more effective than the single injection technique in the long-term.
