  1. (A) *P < 0.05. Elongation of tendons in the double-hemisection group was significantly higher than that in the triple-hemisection group when the distance between the most extreme hemisections was 1 cm, 2 cm or 4 cm.
  2. (B) *P < 0.05.: Failure load of tendons in the double-hemisection group was significantly higher than that in the triple-hemisection group when the distance between hemisections was 0.5 cm or 1 cm, or the distance between the most extreme hemisections was 1 cm, 2 cm or 4 cm.
