• Purpose. To compare the efficacy of autologous blood injection versus corticosteroid injection for lateral epicondylitis. Methods. 21 men and 59 women (mean age, 45.2 years) presenting with lateral epicondylitis were randomised to receive either autologous blood injection (2 ml of autologous venous blood mixed with 1 ml of 2% prilocaine hydrochloride) or corticosteroid injection (1 ml of 40 mg methylprednisolone acetate mixed with 1 ml of 2% prilocaine hydrochloride) given by a single physician. Patients were assessed before (day 0) and after (days 15, 30, and 90) treatment for elbow pain (using a visual analogue scale [VAS]), function (using the patient-rated tennis elbow evaluation [PRTEE] questionnaire), and grip strength (using a hydraulic hand dynamometer). Patients were followed up at 6 months by telephone to assess elbow pain using the VAS. Results. No complications (infection, skin atrophy, neurovascular damage, or tendon rupture) were noted. 10 patients reported increased pain for up to 2 days after autologous blood injection. In both groups, the VAS score for elbow pain, PRTEE score, and grip strength improved significantly after treatment (p=0.0001), but the pattern of improvement differed. Compared with autologous blood injection, corticosteroid injection improved all 3 scores at a faster rate over the first 15 days (p=0.0001), and then started to decline slightly until day 90. After autologous blood injection, all 3 scores improved steadily and were eventually better (p=0.0001). If a 37% decrease in PRTEE is defined as complete recovery, 38 (95%) of patients with autologous blood injection and 25 (62.5%) of patients with corticosteroid injection achieved complete recovery (p=0.0001). Conclusion. Autologous blood injection was more effective over the follow-up period than corticosteroid injection in improving pain, function, and grip strength. It is recommended as a first-line injection treatment because it is simple, cheap, and effective.
