Background: The lateral epicondylitis affects up to 3% of the population, particularly adults between 30 and 50 years of age. The aim of this study to evaluated the efficacy of local infiltration of autologus Platelet Rich Plasma in chronic Tennis elbow.

Material & Methods: A prospective study done on 40 patients with complaint of pain in elbow, coming to RBM Hospitals, Bharatpur, Rajasthan. All patients who came to outpatient department of Orthopaedics with tennis elbow were included in the study. The procedure was done under the guidance of physician and an assistant to aid in preparation of a PRP, maintenance of aseptic technique and a radiologist for identifying the site of pathology by ultrsound. Immediately after the injection, the patient was kept in a supine position without moving the arm for 15 minutes. A 100-mm visual analog pain score (0, no pain; 100, worst pain possible) were used as outcome measures. A final follow-up overall evaluation was also done at 12th week.

Results: Our study showed that maximum incidence was in 2^nd (25%) & 3^rd decade (30%) with the mean age of 31.5 years. Male preponderance (60%) was occurred in the current study. The majority of tennis elbow occurred in farmers (25%), sportsman (25%) followed by factory workers (20%) & housewife (15%). The mean vas score of all patients at the time of PRP injection was 6.98, which decreases to 2.73 at the 12th week follow up, it was statistically significant (P<0.0001***).

Conclusion: We concluded that autologus PRP injection may be an effective and safe treatment option for patients presenting with tennis elbow.
