Introduction: Chronic painful tendon disorders are common in both sport persons and common individuals. Lateral epicondylitis (tennis elbow) is relatively more common among active individuals in the general population. Typical signs and symptoms include pain and tenderness over the lateral epicondyle, exacerbated by resisted wrist extension and passive wrist flexion and impaired grip strength. Aim of the study -To find whether autologous blood provides comparable functional outcome over local steroids and hence whether it can replace steroids in treatment of tennis elbow. Materials and Methods: Patients with nontraumatic elbow pain attending the OrthopaedicsOut patient Department of Patna Medical College Hospital from Sep 2015 to May 2019. The participating subjects were randomly grouped into two groups (steroid (Group A) and autologous blood (Group B)). Pain the subject’s affected elbow was measured using Visual analogue Score (VAS). Results: Initially, both the groups had comparable initial VAS scores. At 1 month follow up, steroid group showed a significantly greater improvements in mean VAS scores when compared to autologous blood group. However, at 6 months follow up, steroid group showed no statistically significant difference in mean VAS scores when comppared to autologous blood group. Conclusion: From the current study, we concluded that both local corticosteroid and autologous blood were equally efficacious in the treatment of chronic lateral epicondylitis of elbow.
