An anchor has a pointed end portion may be utilized to form an opening in a bone in a patient's body. The anchor is moved into the opening formed in the bone in the patient's body with a suture connected to the anchor. The suture may then be utilized to retain body tissue in a desired position relative to the bone. The body tissue may be either hard or soft body tissue. If desired, the anchor may be utilized in conjunction with layers of soft body tissue. When a suture is used it may be secured by connecting a retainer with the suture. Alternatively, sections of the suture may be interconnected. It is believed that it may be preferred to secure the suture in place after at least a predetermined tension has been established in the suture and / or a predetermined force has been transmitted to the body tissue. The suture may be secured in place by exposing a retainer to ultrasonic vibratory energy or by applying the ultrasonic vibratory energy directly to sections of the suture.
