Introduction: Although the name “tennis elbow” is widely used (albeit informally), the ailment is not limited to tennis players. It usually manifests between the ages of 35 and 50 years, and shows no sex predilection. Extensor carpi radialis brevis muscle fibrosis and microtears are noted due to overuse or recurrent wear and tear at its tendinous origin. The most common complaint in individuals with lateral epicondylitis is pain over the lateral aspect of the elbow. The choice of therapy for each case is based on the patient’s needs and the physician’s protocol. The core of treatment is conservative care, with improvements recorded in up to 95% of cases. In cases of recalcitrant lateral epicondylitis, local corticosteroid injections and regenerative techniques such as low intensity ultrasound therapy (LIUST) are becoming increasingly popular. The goal of this trial was to assess the effectiveness of Low Intensity Ultrasound therapy (LIUST) and local corticosteroid injection in treating refractory cases of lateral epicondylitis.

Materials and Methods: 52 patients, fulfilling the inclusion and exclusion criteria were included in the study, and were randomly divided in to two groups; Group I received local corticosteroid injection (n=26) while Group II was treated with locally directed low intensity ultrasound therapy (n=26). Patients were evaluated at 2, 6 and 12 weeks after treatment. Evaluation was done using VAS score and Patient Related Tennis Elbow Evaluation (PRTEE). Intergroup comparisons were made using the unpaired student’s t-test for normally distributed variable. All hypothesis tests were two-tailed. A value of p
