Abstract:
1. A system comprising: a tether having a first portion and a second portion, wherein the second portion is configured to be coupled to a tissue graft, wherein the tether comprises a flexible member; and an anchor insertable into a tunnel formed in a bone proximate a graft site, wherein the anchor receives the first portion such that the first portion is slidable in a first direction with respect to the anchor, and the first portion is lockable by the anchor and by the first portion at any of a plurality of positions of the tether relative to the anchor to prevent sliding of the first portion in a second direction opposite to the first direction; wherein the anchor comprises a plurality of passageways that define a pathway along which the flexible member is slidable along in the first direction; wherein the tunnel passes through the bone between the graft site and an anchoring side on an opposite side of the bone from the graft site, wherein the anchor comprises a retention surface and an outer surface opposite the retention surface, wherein, when the anchor is inserted into the tunnel, the retention surface abuts the anchoring side, wherein the first portion slides in the first direction in response to tension tending to draw the flexible member from the outer surface.
