Eligibility
Age
18 Years to No maximum
Inclusion criteria
Inclusion criteria: Patients diagnosed with lateral epicondylitis of the elbow; painful clinical presentation on the lateral aspect of the elbow and magnetic resonance imaging showing partial insertion tear of the extensors less than 50%; age over 18 years; both genders.
Exclusion criteria
Exclusion criteria: Patients with complete or partial tears greater than 50% of the extensor muscles or partial tears secondary to previous trauma or fracture; patients who have undergone previous surgery on the affected elbow or who have undergone previous elbow infiltration in the last 6 months; patients with other associated causes of painful elbow pathology such as osteoarthritis, loose bodies in the joint, joint stiffness; concomitant neck pain or other arm pain, symptoms suggestive of radicular neurological conditions; patients with active infections; pregnant women; and patients using immunosuppressants or chronic corticosteroid therapy.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Improvements are expected in pain, function, and muscle strength parameters after the three interventions (hyaluronic acid, platelet-rich fibrin, and corticosteroid) at one, three, and six months after the injections. These improvements will be verified using the visual analogue scale for pain and the quick disabilities of the arm, shoulder and hand functional questionnaire, the Mayo elbow performance score questionnaire, and handgrip strength, measured using hand dynamometry with a calibrated dynamometer, with the participant positioned according to the American Society of Hand Therapists standardization. Three consecutive measurements will be taken, and the average of the values ??obtained, expressed in kilograms-force, will be considered;To assess the existence of superiority between infiltration procedures after statistical analysis, during the evaluated period | — |
Secondary
| Measure | Time frame |
|---|---|
| To find statistically significant differences in comparative results between interventions using the visual analogue scale, quick disabilities of the arm, shoulder and hand, Mayo elbow performance score, and handgrip strength assessments;To determine whether platelet-rich fibrin application is superior or not inferior compared to corticosteroid and hyaluronic acid applications | — |
