A surgical method comprises the steps of (a) inserting a needle into a patient, a suture thread being connected to the needle, (b) moving the needle inside the patient to insert the needle into internal body tissues of the patient at a preselected surgical site inside the patient, (c) withdrawing the needle from the internal body tissues so that the suture passes through the internal body tissues, and (d) removing the needle from the patient. In a series of subsequent steps, (e) a knot is tied in the suture outside the patient, (f) the suture is manipulated to slide the knot into the patient until the knot is juxtaposed to the internal body tissues at the surgical site, (g) the suture is severed in juxtaposition to the knot at the surgical site, and (h) a severed portion of the suture is removed from the patient. A surgical instrument assembly for performing the method comprises an arcuate needle and a tubular member. The needle has a spring bias construction tending to bend the needle into an arcuate configuration and a suture thread is connected to the needle. The tubular member has an inside diameter slightly larger than an outer diameter of the needle, the needle being disposed in a straightened configuration inside the tubular member. The suture extends out through an end of the tubular member.
