Figure 1

The model of tendon hemisection. (A) double hemisection tendon, (B) triple hemisection tendon, and (C) complete tendon. The distance between hemisections in A and B was 0.5 cm. The length of the test area of the tendons ( distance between the two clamp lines) was 6 cm. The central point, clamping line, and hemisection planes of the tendon are marked (indicated by blue, black, and red arrows, respectively). On the tendons with hemisections, incisions were cut to half or more of the cross-sectional area of the tendon. The central point and clamp lines are marked on the intact tendon.
