Isolated biceps tenodesis by double row for pulley lesions

Abstract

Objective: To explore clinical outcome of isolated arthroscopic biceps tenodesis by double row for pulley lesions. Methods: Forty-nine patients with pulley lesions were treated from July 2017 to June 2018 in the Department of Sport Medicine, the Affiliated Zhongshan Hospital of Dalian University by isolated arthroscopic biceps tenodesis by double row. Patients were divided into 2 groups according to the intraoperative damage of the pulley system. In group A, there were 16 patients with isolated superior glenohumeral ligament/coracohumeral ligament (SGHL/CHL) complex lesions, including 9 males and 7 females, aged (55±6) years. In group B, there were 33 patients (15 males and 18 females, aged (57±8) years) with SGHL/CHL complex and adjacent supraspinatus tendon and/or subscapularis tendon articular-side partly tears. Patients in two groups were treated with different isolated arthroscopic biceps tenodesis by double row. Constant-Murley shoulder score and pain visual analogue scale (VAS) score were assessed before operation and 3, 6, 12 months after the operation. Postoperative complications were also recorded in two groups. The t test was used to compare the quantitative data within and between two groups. Results: All 49 patients were followed up for 12 to 24 months with an average of (17±6) months. The first-stage healing was achieved in all incisions in the two groups. No surgical complications related to revision, infection, Popeye syndrome and cramping pain were observed in either group. There was 1 case treated by secondary arthroscopy for retrauma in group B. The Constant-Murley shoulder score in group A before the operation was 46±10, and it was increased to 89±9 at the 12 months post operation(t=-22.637, P<0.05); and it was 39±10 and 87±8 before and 12 months after the operation respectively in group B (t=-44.849, P<0.05). The VAS scores in the two groups were both decreased significantly at the 12 months post operation when compared with those before the operation (0.68±0.70 vs 5.25±0.27 and 0.72±0.83 vs 5.69±0.84, respectively) (t=29.007, 37.079, both P<0.05). Conclusion: Isolated arthroscopic biceps tenodesis by double row can relieve pain, recover functions of shoulder joint effectively, and achieve a satisfactory outcome in the treatment of pulley lesions.
