The surgeon needs a suture material that will not degrade over time but becomes encapsulated and supports a tissue structure that will continue to be exposed to pressure and stretching forces throughout the patient's life.These physical properties are best described by a suture that:
A) is nonabsorbable, has good tensile and knot strength, and is the appropriate diameter for the tissue.
B) has a large diameter, is nonabsorbable, is highly reactive, and is a monofilament.
C) is a monofilament, is synthetically manufactured, is absorbable, and has a large diameter.
D) has good tensile strength, memory, and ease of tying and is absorbable.

Physical characteristics of sutures can be measured or visually determined and include the following properties: Diameter (size)is measured in millimeters,and expressed in USP sizes with zeroes.The finer diameter (smaller size)provides better handling qualities and small knots.Improved suturing techniques are possible with sutures of finer diameter.Tensile strength is defined as the amount of weight (breaking load)necessary to break a suture (breaking strength); it varies according to the type of suture material.Knot strength is the force necessary to cause a given type of knot to slip,either partially or completely.The most common nonabsorbable suture materials are silk,nylon,polyester fiber,polypropylene,and stainless-steel wire.
