1. A method of anchoring a suture, said method comprising:
- rotating a cutting tool and moving the rotating cutting tool into body tissue;
rotating a thin elongated member and moving the rotating thin elongated member into the body tissue;
freeze drying a body tissue;
inserting a suture into a passage in the freeze dried body tissue; and
inserting the freeze dried body tissue into a patient'"'"'s body with the suture extending the passage in the freeze dried body tissue, wherein said steps of rotating a cutting tool and moving the rotating cutting tool into the body tissue and said steps of rotating a thin elongated member and moving the rotating thin elongated member into body tissue are performed together.

Abstract
An improved suture anchor is formed from body tissue. The body tissue is shaped to a desired configuration for the anchor and defines a passage through the anchor. A suture is inserted into the passage in the body tissue of the anchor. The anchor is then positioned in a patient'"'"'s body with a suture extending into the passage in the anchor. The anchor may be formed of osseous body tissue, hard compact bone, dense connective body tissue, or other body tissue. The body tissue may be dried so that it absorbs fluid and expands upon being inserted into a patient'"'"'s body.

- 18. A method of retaining portions of first and second tissue elements in a patient'"'"'s body against movement relative to each other, said method comprising the steps of freeze drying a body tissue, engaging at least one of the first and second tissue elements in the patient'"'"'s body with the freeze dried body tissue, and securing the first and second body tissue elements together by transmitting force between the first and second tissue elements through the freeze dried body tissue, such that the first and second tissue elements are retained against movement relative to each other, wherein the first tissue is bone tissue and the second tissue is soft tissue and wherein the freeze dried body tissue includes a bone tissue having a lume.
