Effect of suture structure on knot performance of polyamide sutures a

The knot performance of monofi lament and braided polyamide (PA) sutures has been characterised by applying two d iffe rent knots with two, three and four th rows. It is observed that generally granny knot and braided structure have better knot perfo rmance. An additional throw does not increase the fo rce required to break the suture. Suture size is also important for knot performance and the sutu res behave di ffe rently when they are wet.
