Summary: For patients with chronic unilateral lateral epicondylitis, local corticosteroid injection may result in lower rates of complete recovery and higher rates of symptomatic recurrence at both 6 months and 1 year after treatment, compared to use of a placebo injection. (In other words, for a patient with unilateral epicondylitis, NOT treating with a local corticosteroid injection may lead to a better long-term outcome).
