Influence of suture material on biomechanical and histological indicators of Achilles tendon heeling in rabbits
This study shows on a rabbit model in vivo the importance of suture material elasticity in Achilles tendon healing. Tendon reconstruction was performed on 30 rabbits divided into three groups of 10 animals, according to the suture material. Tendons were sutured by the Krackow suture. Steel wire as a stiff material, polypropylene as a plastic material, and polybutester as a material that shows elasticity and resistance to deformities were used. In all the animals the unoperated, contra lateral limb served as control. A servohidraulic jack was used to set a maximum loading capacity until the breaking point (Fmax) and drawing ability (A). The breaking strength of tendons reconstructed by polybutester was not statistically different in comparison to the breaking strength of control tendons, but were signififi cantly higher in comparison to tendons sutured by wire or polypropylene. Different histological staining methods were used to show the parameters of healing tendon tissue. The collagen fi ber structure and arrangement, and the cellularity of tendon scar tissue sutured by polybutester are more similar to those of the control tendon. Achilles tendon suturing with polybutester is benefi cial for tendon healing, so its clinical use is recommended.
