BackgroundInjections are a good alternative to conventional treatment-resistant cases with rotator cuff (RC) lesions before operation. Currently, different injection methods are used in RC lesions.ObjectiveTo evaluate the efficacy of different injection methods (platelet-rich plasma [PRP], corticosteroid [COR] and prolotherapy [PRO]) in RC tendon lesions.MethodsOne hundred and twenty-nine patients were divided into 4 groups as PRP, COR, PRO and the lidocaine group. Subacromial injection was applied to all groups. They were evaluated using the Visual Analogue Scale (VAS), American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), and Western Ontario Rotator Cuff Index (WORC) at 3, 12 and 24 weeks post-injection.ResultsIn the COR group in the 3rd week, VAS and WORC scores were significantly lower than the other groups (p< 0.01 and p< 0.05 respectively). In the PRP group in the 24th week, VAS and WORC scores were found to be significantly lower than the COR group (p< 0.01 and p< 0.05 respectively). In the COR group in the 3rd week the ASES score was found to be significantly higher than the PRP and PRO group (p< 0.01).ConclusionIn patients with RC lesions, corticosteroid injection provides short-term relief for pain, function, and quality of life, while PRP injection works for long-term wellbeing. For all types of applied injections, improvement in pain, function and quality of life were observed.
