Hypothesis: We hypothesized that in patients with rotator cuff tears, the clinical outcome of suture bridge repair (BR) is superior to that of simple suture repair (SR). Methods: Thirty-seven patients with rotator cuff tears were candidates for this study and divided into 2 groups: 21 patients with SR and 16 patients with BR. Patient profile was as follows: average age of 62.0years in the SR group and 61.1years in the BR group; average tear size (longitudinal X transverse) of 10.7cm2 in the SR group and 8.4cm2 in the BR group; average symptom period of 7.2months in the SR group and 5.0months in the BR group. Traumatic onset was noted in 13 patients in the SR group and 10 patients in the BR group. Passive elevation of the shoulder was commenced immediately after surgery, and at 6 weeks after surgery, active motion of the shoulder was allowed. Range of motion, muscle strength, visual analogue scale, and Japanese Orthopaedic Association (JOA) score were measured preoperatively and postoperatively. Postoperative re-tear was evaluated using MRI at 1 year after the surgery. The Mann-Whitney test and Chai-square test were used for statistical analysis. A P value less than 0.05 was considered significant. Results: No statistical differences between the 2 groups were found in the preoperative patient profile, postoperative JOA score, and re-tear rate (8/21 cases in the SR group and 5/16 in the BR group, P = 0.481). Conclusion: We failed to observe any apparent difference of the clinical outcome between SR and BR. It remains to be clarified in a larger-scale study.
