Original Contribution


The purpose of this study was to provide information on textile behaviour of suture materials in order to assist surgeons in their selection of adequate sutures for specific surgical applications. Commercially available absorbable and non-absorbable (both braided and monofilament) coated sutures of size 2-0 were used in this study. A comparative study between two different manufacturers, i.e. Johnson & Johnson (USA) and Sutures India (India), was also carried out during this work. On the basis of mechanical tests including suture-to-suture coefficient of friction, suture-to-skin coefficient of friction, bending rigidity, handling characteristic, i.e. knot tie-down roughness of suture materials were studied. Obtained results show that among these tests, suture-to-suture coefficient of friction and bending rigidity have significant effect on the handling characteristic of suture. Higher coefficient of friction exhibited by braided suture suggests that, despite of coating, asperities formed on these sutures resulted in their higher friction than monofilament ones.
