Background: Chronic lateral epicondylitis, or tennis elbow, affects individuals irrespective of age, gender, or occupation, impacting their functional arm movement and quality of life. Percutaneous tenotomy presents a minimally invasive treatment option, yet its efficacy across different demographic groups remains underexplored.
 Methods: This retrospective study at the Department of Orthopaedics, Dr. RPGMC Kangra at Tanda, included 45 patients undergoing percutaneous tenotomy for chronic lateral epicondylitis. Patients were assessed pre-operatively and at intervals up to 36 months post-operation using NRS, DASH, and Oxford scores.
 Results: Significant improvements in pain and functional scores were observed across all demographic groups, with no single demographic factor significantly influencing treatment outcomes.
 Conclusion: Percutaneous tenotomy is universally effective in treating chronic lateral epicondylitis, offering significant pain relief and functional recovery across diverse demographic groups.
