Abstract
A ratcheting inserter device for tensioning a knotless suture anchor includes an outer inserter shaft and an inner inserter shaft having a common longitudinal axis. A ratcheting mechanism provided between the inner inserter shaft and the outer inserter shaft permits rotation of the inner inserter shaft in one direction relative to the outer inserter shaft. The outer inserter shaft has a protrusion at a distal end that is received by an anchor outer sleeve of a suture anchor to prevent relative rotation thereof, and the inner inserter shaft has a projection at the distal end that is received by an inner core of the anchor for rotational movement therewith. The ratcheting inserter device rotates the inner core of the suture anchor to spool and tension suture thread. Thereafter, the ratcheting mechanism is disengaged and the inner inserter shaft is forced axially into the anchor outer sleeve.

17. A method for securing a suture anchor into a bone comprising:
-
providing a suture anchor comprising an anchor inner core and an anchor outer sleeve having an open bore hole at a proximal end for receiving and enclosing a first portion of the anchor inner core with a second portion of the anchor inner core extending away from the proximal end of the anchor outer sleeve; driving the suture anchor into bone with an inserter device to dispose the proximal end of the anchor outer sleeve adjacent a bone surface; tensioning suture threads coacting with the suture anchor; and driving the anchor inner core into the anchor outer sleeve. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)
