Suture with least adhesion to tissues and high plasticity is:: (A) Nylon, (B) Prolene, (C) Polyglycolate, (D) PDS
Answer is B. Polypropylene (prolene) is an extremely inert suture with a (low) tissue reactivity and good tensile strength comparable to nylon. It has a very slippery surface with low adherence to tissues. Its extreme smoothness does compromise knot security and extra knots are required to prevent loosening of the suture.
