Serial clinical and MRI follow\u2010up assessments were carried out at 1\u00a0month, 6\u00a0months and 12\u00a0months after surgery. Twenty healthy volunteers were involved and were examined with clinical and MRI assessments. Clinical assessments included Constant Score (CS), the American Shoulder and Elbow Surgeons (ASES), the modified University of California, Los Angles (UCLA) scores and Visual Analog Scale (VAS). The region of interest of tendon healing was defined directly over the medial suture anchor on T2\u00a0mapping.

The T2 values of the healing site significantly decreased over time (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001) and were comparable to those of healthy tendons at 12\u00a0months (n.s.).
