Patients were divided into 2 groups based on different tension after tenodesis: isotension group (tenodesis in situ at the bicipital groove followed by resection of proximal tendon insertion) and low-tension group (resection of proximal tendon transection followed by tenodesis of the residual tendon stump in the bicipital groove). Shear wave elastography (SWE) was used to measure the elastic modulus of the LHBT preoperatively and postoperatively at 1 week to evaluate the effects of the 2 fixation methods on the tension of the LHBT. Functional outcome scores (including the American Shoulder and Elbow Surgeons [ASES] score, Constant-Murley score [CMS], visual analog scale [VAS] score, and long head of the biceps [LHB] score) were collected, and the minimal clinically important difference (MCID) for each functional score was calculated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      A total of 50 patients in the isotension group (mean follow-up, 26.5 \u00b1 4.7 months) and 73 patients in the low-tension group (mean follow-up, 26.0 \u00b1 6.4 months) were included in this study. SWE showed no preoperative to postoperative stiffness change in the isotension group (6.75 \u00b1 1.07 m\/s to 6.70 \u00b1 1.01 m\/s;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .930) but reduced stiffness in the low-tension group (5.88 \u00b1 1.30 m\/s postoperatively vs 6.79 \u00b1 1.35 m\/s preoperatively;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .001).
