Randomized Controlled Trial Multicenter Study Comparative Study
Comparison of autologous blood, corticosteroid, and saline injection in the treatment of lateral epicondylitis: a prospective, randomized, controlled multicenter study.
We compared saline, corticosteroid, and autologous blood injections for lateral epicondylitis in a prospective, blinded, randomized, controlled trial. The null hypothesis was that patient-rated outcomes after autologous blood injection would not be superior to corticosteroid and saline injections. ⋯ In this prospective, randomized, controlled trial, autologous blood, corticosteroid, and saline injection provide no advantage over placebo saline injections in the treatment of lateral epicondylitis. Patients within each injection group demonstrated improved outcome scores over a 6-month period.
