Lateral epicondylitis, also known as Tennis Elbow, causes pain and limits daily activities for many people. This research compares two treatment methods to see which might be better for relieving symptoms. The study focuses on adults aged 18 to 70 who have had chronic elbow pain for at least six months and have not improved after other treatments. Participants will be randomly assigned to one of two treatments: Ultrasound-guided Percutaneous Tenotomy or Open Surgical Debridement. The Tenex procedure uses a special needle guided by ultrasound to remove damaged tissue with ultrasonic energy in a doctor's office under local anesthesia. The open surgical debridement involves a surgeon making an incision to remove damaged tendon tissue under anesthesia in a surgical center. Throughout the study, participants will have follow-up visits at 3 weeks, 6 weeks, 3 months, 6 months, and 12 months after treatment to check progress. They will also complete questionnaires about their symptoms and function during these visits. Researchers will compare complications and functional outcomes between the two treatments to better understand their effects.
