The Clinical Results of Percutaneous Drilling in the Treatment of Chronic Lateral Epicondylitis.

Abstract

Lateral epicondylitis is one of the leading orthopedic problems encountered in daily practice. Treatments are more symptomatic than curative. Percutaneous drilling is a minimally invasive method that provides satisfactory results. The aim of this study was to evaluate patients who had undergone percutaneous drilling for chronic lateral epicondylitis. The study included 31 patients who underwent surgical percutaneous drilling because of chronic lateral epicondylitis between 2018 and 2021. The patients were evaluated with respect to demographic characteristics, including age, gender, body mass index (BMI), occupation, education level, hobbies, dominant side, and smoking status. The VAS (Visual Analog Scale) pain scores, PRTEE score (Patient-Rated Tennis Elbow Evaluation - a lateral epicondylitis function scale), and Roles-Maudsly score were examined preoperatively and at one and 12 months postoperatively together with grip strength measured with a Jamar hand dynamometer. Statistically significant improvements were determined in the VAS score during activity from 8.9 preoperatively to 2.06 at 12 months postoperatively (p<0.01), and in the PRTEE score, from 64.12 preoperatively to 20.61 at 12 months postoperatively (p<0.01). The Roles-Maudsly score at 12 months postoperatively was determined to be excellent in 13 (41.9%) patients, and good in 14 (45.2%). Mean grip strength increased from 69.55 before treatment to 90.97 at the end of 12 months postoperatively. Autobiological treatments are at the forefront of current treatments for tendinopathies. Percutaneous drilling is a closed method and can be considered an ideal method in the treatment of tendinosis caused by inflammation and mesenchymal stem cells (MSCs) contained in hematoma. It is also an advantageous treatment method for patients with aesthetic concerns as it does not leave any scar tissue and has a low risk of complications.
