Abstract

ObjectiveLateral and medial epicondylitis are relatively common diseases, but they do not improve quickly and are known to reduce patients' quality of life. Much research has been done on Platelet‐Rich Plasma (PRP) as a treatment for lateral epicondylitis, but research on medial epicondylitis is lacking. The purpose of this study is to compare: (i) the pain intensity; and (ii) the functional outcome between the simultaneous treatment of medial and lateral epicondylitis and the treatment of only lateral or medial epicondylitis using PRP.MethodsIn this retrospective study, 209 patients treated with PRP on epicondylitis between March 2018 and December 2021 were enrolled. Simultaneous treatment was underwent 68 patients (group I). Seventy patients were treated for lateral epicondylitis (group II). The remaining 71 patients were treated for medial epicondylitis (group III). The visual analogue scale for pain (VAS) and the Mayo elbow performance score (MEPS) were evaluated for clinical outcomes at the initial visit and 6 months after injection.ResultsVAS for pain and MEPS showed significant improvement in all three groups compared to before treatment. There was no significant difference between three groups on –ΔVAS (P > 0.05). However, in case of ΔMEPS, group III showed significantly lower compared to groups II and III (P < 0.05). No patients showed worsening of symptoms or complications during the treatment.ConclusionPRP injection for the patient with elbow medial and lateral epicondylitis can be treated effectively simultaneously in terms of pain. From a functional point of view, the effect of simultaneous treatment may be lessened than in the case of only lateral and medial treatment.
