Abstract:
Objective To provide the biomechanical basis of plantaris tendon for clinical autotransplantation. Methods Fifteen plantaris tendons from 8 fresh adult cadavers were cut into 56 segments with about 6 cm lengths in each. The segments were divided into 3 groups: upper,middle,and lower segments. Fifty segments were taken for the tensile test,while the other six segments were loaded under 30 MPa,40 MPa,and 50 MPa respectively. The histologic structure of the tendons was observed under the microscope after presumptive load. Results The average limit load,tensile strength and elastic modulus of the plantaris tendon were (83.19?42.52) N,(60.32?21.80) MPa,and (714.83?285.44) MPa respectively. The tensile strength of the lower segments was significant higher than the upper and middle segments. Conclusion The biomechanical property of the plantaris tendon is accommodative for autografting.
