Fatigue strength (newtons\u2009\u00d7\u2009cycles) was determined using cyclic tensile testing on the repaired tendons with gradually increasing loads. The load (newtons) and number of tensile testing cycles when a 2\u2009mm gap or failure occurred at the repair site were recorded.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Fatigue strength at 2\u2009mm gap formation was significantly greater in the Tsuge cross and Tsuge cross short techniques than in the Tsuge normal technique. Fatigue strength at failure was significantly greater with the Tsuge cross short technique than with the Tsuge normal technique. Detailed analysis suggested that gap prevention using the Tsuge cross and Tsuge cross short techniques may be caused by tendon tightening by cross suturing.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The Tsuge cross and Tsuge cross short suture techniques prevent gap formation, which could hinder tendon healing during early active motion rehabilitation.
