Technical considerations in knot construction, part III. Knot asymmetry

Lactomer and the Polyglactin 910 are coated synthetic braided absorbable sutures commonly used for dermal wound closure. Biomechanical performance tests demonstrated superior performance characteristics of the Lactomer sutures. Using narrow diameter sutures, the Lactomer sutures exhibited superior knot holding forces over the Polyglactin 910 sutures. Moreover, knot security could be reliably achieved with asymmetric and symmetric knots using the Lactomer sutures.
