Background: Platelet rich plasma and corticosteroid injection have both been suggested to treat chronic lateral epicondylosis. The aim of this study was to compare the safety and effectiveness of corticosteroid, PRP and xylocaine infiltration for lateral epicondylosis. Materials and Methods: 150 patients with chronic lateral epicondylosis were randomly divided into three groups. Group A was treated with a single injection of 2 ml of corticosteroid mixed with 1 ml of xylocaine, Group B with 2 ml of PRP mixed with 1 ml of xylocaine and Group C with 3 ml of 2% xylocaine through peppering needle technique. Pain and functional improvements were assessed using visual analogue scale (VAS) and Nirschl’s staging at 0,2,6,12,26 and 52 weeks. Results: Baseline evaluation showed no difference between the three groups (p>0.05). Analysis at 2 weeks showed no difference in Nirschl staging but showed significant decrease in VAS score in favour of corticosteroid group. No statistically significant difference was noted between groups at 6 weeks (p>0.05). At 12 weeks VAS score was comparable but Nirschl stage was significantly low in corticosteroid group. Evaluation at 26 and 52 weeks demonstrated a statistically significant difference between groups favouring PRP group (p<0.05). Conclusion: PRP, Corticosteroid and Xylocaine are safe and effective in treatment of lateral epicondylosis. Both steroid and xylocaine are effective on a short term period. However, on long term follow-up, PRP seems to be the more effective treatment with more persistent efficacy than corticosteroid and xylocaine in relieving pain.
