Methods and materials: 68 Patients diagnosed as Tennis elbow and treated at our institute between March 2017 to February 2018 and those who were followed up in Out Patient Department upto June 2018 were retrospectively studied. Patients with polyarthritis, arthritis of the Elbow, previous fracture of the elbow and patients with neurological condition were excluded. 68 patients diagnosed with chronic lateral epicondylosis were randomly divided into two groups. Group A with 2 ml of PRP mixed with 1 ml of 2% xylocaine and Group B with Bracing and conservative treatment( NSAIDS and ice fomentation, physiotherapy). Pain and functional improvements were assessed using visual analogue scale (VAS) and mayo scoring at 0, 1, 2, 4, 12 and 24 weeks.

Results: Among 68 patients with tennis elbow (39 males and 29 females) post-PRP injection and Conservative treatment (Bracing, NSAIDS) significant differences were observed between VAS and Mayo elbow performance score score at baseline and after 1wk, 2wk, 4wk, 12wk and 24wk (P<0.007).At the end of first week of treatment recovery or improvement was reported in 86.11% patients (31) in the PRP group and 53.13% in the brace group.

Conclusions: Our results demonstrated good functional outcome with patient treated with PRP with 2% xylocaine and it sustained over longer period of time. Intially as well as later on results in patients treated with PRP with 2% xylocaine was better in comparision with conservative treatment (Bracing, NSAIDS and ice fomentation). It is safe and a significant improvement has been observed in VAS score and Mayo elbow performance score for tennis elbow. On long term follow-up, PRP seems to be the more effective treatment with more persistent efficacy than conservative treatment (Bracing and NSAIDS) in relieving the pain.
