Statistical Analysis of Percutaneous Tenotomy Outcomes in Chronic Lateral Epicondylitis

Background: Chronic lateral epicondylitis significantly impacts individuals' quality of life by causing persistent elbow pain and limited grip strength. Percutaneous tenotomy offers a promising approach to address this condition, yet its long-term efficacy remains underexplored. Methods: This retrospective study assessed 45 patients who underwent percutaneous tenotomy for chronic lateral epicondylitis. Pain and functional outcomes were evaluated using NRS, DASH, and Oxford scores over a 36-month follow-up period. Results: Significant improvements were observed in all outcome measures across the follow-up period, indicating sustained pain relief, functional recovery, and enhanced quality of life post-tenotomy. Conclusion: Percutaneous tenotomy proves to be an effective and durable treatment for chronic lateral epicondylitis, offering significant benefits in terms of pain reduction and functional improvement over time.
