This clinical trial is focused on studying the treatment of tennis elbow, a condition medically known as lateral epicondylitis. This condition causes pain around the outside of the elbow. The study compares two treatments: a surgical procedure called debridement arthroscopic, which involves cleaning out damaged tissue from the elbow, and an injection treatment using cytokine-rich autologous serum. This serum is a special protein-rich solution made from the patient’s own blood.
The purpose of the study is to evaluate how effective these treatments are in reducing pain over a medium-term period of six months. Participants in the study will be randomly assigned to receive either the surgical procedure or the serum injections. Those receiving the serum treatment will have two injections spaced 14 to 21 days apart. If only one injection is given due to medical reasons, the participant will still be monitored as if they had received both injections.
Throughout the study, participants will be closely monitored for any unexpected side effects, such as infections or severe allergic reactions. The study aims to provide valuable information on which treatment is more effective in managing pain for individuals with chronic tennis elbow.
