Operative Treatment of Medial Epicondylitis: A Comparative Analysis of the Clinical Outcomes between the Suture Anchor Group and the Non-suture Anchor Group

Background: The The purpose of this study was to make a comparative analysis of the clinical outcomes after the operative treatment of refractory medial epicondylitis between the suture anchor group and the non-suture anchor group. Methods: We enrolled 20 patients (7 men and 13 women) with recalcitrant medial epicondylitis who were able to receive operative treatment in a minimum of an 18-month follow-up. The mean age was 48.6 years (range, 36–59 years). The patients were allocated into either the suture anchor group (7 patients) or the non-suture anchor group (13 patients). We evaluated clinical outcomes using the visual analog scale (VAS), the pain grading system of Nirschl and Pettrone, and postoperative grip strength. Results: The VAS score decreased from 8.8 to 2.0 for the suture anchor group and from 8.6 to 1.3 for the non-suture anchor group (p=0.16). The postoperative grip strength was 95%, 93% of the non-treated arm in both groups (p=0.32). The postoperative satisfaction level was good in 5 patients and fair in 2 for the suture anchor group and excellent in 5 patients, good, in 4, and fair, in 4 for the nonsuture anchor group (p=0.43). The clinical outcomes did not show a statistically significant difference between the two groups. Conclusions: We found that patients with recalcitrant medial epicondylitis were treated reliably with satisfactory clinical outcomes whether or not suture anchors were used. We believe the use of suture anchors when more than 50% of the tendon origin is affected provides an effective and favorable treatment modality. (Clin Shoulder Elbow 2015;18(4):221-228)
