      Protocol synopsis Title of Study: A Prospective, Randomized, Multi-Center Clinical Study to&#xD;
      Evaluate the Safety and Efficacy of Q-Fix All-Suture Anchor in Arthroscopic Repair of&#xD;
      Shoulder Soft Tissue in Chinese Patients&#xD;
&#xD;
      Study Design: Prospective, multicenter, comparative, randomized, concurrent control Study&#xD;
      Type: Randomized Controlled Trial (RCT) Study Product: Q-Fix All-Suture Anchor Comparison&#xD;
      Group Twinfix Ti Suture Anchor Study Purpose: The purpose of this study is to evaluate the&#xD;
      safety and efficacy of Q-Fix All-suture Anchor in patients requiring the repair of soft&#xD;
      tissue of shoulder who receive the arthroscopic repair of soft tissue using Q-Fix All-suture&#xD;
      Anchor, when compared with the patients receiving the treatment with Twinfix Ti Suture&#xD;
      Anchor. The result of this trial will be used for the Q-Fix All-suture Anchor registration in&#xD;
      China.&#xD;
&#xD;
      Primary Objective: The primary objective of this study is to confirm that the clinical&#xD;
      outcome of subjects receiving the treatment with Q-Fix All-suture Anchor is non-inferior to&#xD;
      that of the subjects receiving the treatment with Twinfix Ti Suture Anchor during the same&#xD;
      period, at 6 months after the repair of soft tissue of shoulder, taking the mean Constant&#xD;
      score as efficacy endpoint.&#xD;
&#xD;
      Secondary Objective(s): The secondary objective of this study is to determine the safety and&#xD;
      efficacy of Q-Fix All-suture Anchor at 12 months after repair of soft tissue of shoulder.&#xD;
&#xD;
      Statistical Rationale: The primary efficacy endpoint of this study is Constant score at 6&#xD;
      months after operation. The non-inferiority testing is performed for efficiency of primary&#xD;
      efficacy endpoint; the test hypothesis is as follows:&#xD;
&#xD;
      Invalid hypothesis: H0: μ1-μ2 ≤ -δ Alternative hypothesis: H1: μ1-μ2 &gt; -δ Where, μ1 and μ2&#xD;
      are the mean Constant scores in the test and control group, respectively. δ is the&#xD;
      non-inferiority margin, which is set to 10. The hypothesis will be tested by two-sided t-test&#xD;
      at the alpha level of α=0.025 (one-tailed test). the A non-inferior test will be conducted on&#xD;
      the Constant scores in the test and control groups. The 95% confidence interval for the&#xD;
      difference between two groups will be calculated. If the lower limit of 95%CI for the&#xD;
      efficiency difference between two groups is greater than -9, it is considered that the test&#xD;
      group is non-inferior to the control group.&#xD;
