To Improve Pain and Function, Platelet-Rich Plasma Injections May Be an Alternative to Surgery for Treating Lateral Epicondylitis: A Systematic Review

摘要

? 2021 Arthroscopy Association of North AmericaPurpose: To determine whether platelet-rich plasma (PRP) injection for lateral epicondylitis offers patients comparable outcomes to lateral epicondylar surgery. Methods: Embase, Cochrane Library, and MEDLINE databases were searched using the terms lateral epicondylitis, lateral elbow pain, tennis elbow, lateral epicondylalgia, and elbow tendinopathy individually and combined with the terms platelet-rich plasma injections and lateral epicondylar surgery. We compared pain relief, function between the 2 treatment options, and identified whether PRP injection reduced the incidence of lateral epicondylar surgery. Studies must have compared PRP injections with lateral epicondylar surgery for the treatment of lateral epicondylitis; be of Level I, II, or III evidence; and be written in the English language. Results: Three studies (1 Level II and 2 Level III) met inclusion criteria. Two of the studies suggested that PRP injections offer similar relief as surgery in the short and mid-term, one study reported that PRP injections and surgery had similar outcomes in pain improvement and return to work, whereas 1 study reported that surgery may be a better long-term solution. Conclusions: In comparison with lateral epicondylar surgery, PRP injections offer similar improvements in pain and function for patients suffering from lateral epicondylitis, especially in the short- and mid-term in 2 of the 3 included investigations. Therefore, PRP injections are an appropriate alternative for the treatment of lateral epicondylitis. Level of Evidence: Level III, Systematic Review of Level III or greater evidence.
