Outcome of Percutaneous Release of the Common Extensor Origin for Tennis Elbow

Abstract

Introduction: Tennis elbow occurs due to overexertion of the extremity with repetitive wrist extension and alternating forearm pronation/supination and occurs in 1 to 3% population. Surgical procedures are available like open, percutaneous and arthroscopic common extensor tendon release. Among them percutaneous release is a safe and simple surgical procedure with good-to-excellent results. Material and Methods: A prospective observational study was conducted in 50 patients at National Medical college and Teaching Hospital, Birganj, Nepal for one year duration among age 30 to 60 years with more than 6 months duration of pain and one dose previous steroid injection. Informed consent was taken before procedure. Percutaneous release was performed using 10ml of 2% lignocaine for local anesthesia and 18G needle for tenotomy in minor operation theatre. The patients were assessed by using quick DASH score. Results: Out of 50 patients mean age was 43.50 ± 8.187 years, 31(62%) were female and right side 31(62%) was commonly affected. Mean duration of pain was 9.98 ± 4.359 months. All of the patients had taken treatment previously. The post operative outcome was excellent 48(96%) to good in 2(4%) patients. Mean quick DASH score Preoperative was 63.84 ± 4.87 (range 45.45 to 79.45), at 6 weeks follow up was 10.67 ± 7 .68 (range from 2.27 to 34.09) and at 6 months follow up was 5.86 ± 3.34 (range0.00 to 13.63). There was significant correlation between Quick DASH score at preoperative period and at six weeks follow up (r = .309, P = 0.03) and at six months follow up (r = .555, P < 0.000). No complication was reported. All the patients returned to their normal jobs and activities. Conclusion: The study concluded that percutaneous release of the common extensor origin for tennis elbow is effective treatment for tennis elbow with least complications.
