Abstract: A method for securing a sleeve in a bore hole in bone. The method includes disposing at least a portion of a length of filament into the bore hole, and implanting the sleeve into the bore hole such that a first pathway extending through first and second ends of the sleeve opens in a direction toward the opening of the bore hole and in a direction toward the base of the bore hole. The method also includes pulling at least a portion of the length of filament through the first pathway of the sleeve, thereby forming a first loop configuration extending from the first end and at least one free end of the length of filament extending from the second end. Also included is passing the at least one free end through the first loop configuration to create a one-way cinch.

Abstract: A bone cutting device for forming an undercut in bone. The device includes a rotatable body having an inner surface and outer surface. The inner surface defines an aperture. The inner and outer surfaces are disposed opposite each other and define a sidewall. The sidewall includes a recess extending from the outer surface into the aperture. A cutting arm is cantilevered to the sidewall and disposed within the recess. The cutting arm includes a flexible depression extending into the aperture. An actuating member is longitudinally slidable within the aperture such that sliding the actuating member longitudinally interfaces with the flexible depression and pushes the cutting arm radially outwardly.

Abstract: A system for securing a length of filament in working communication with tissue. The system includes a first filamentary sleeve having a length along a longitudinal axis and a passageway therethrough. The passageway is dimensioned to allow slidable movement therein of a length of filament. Also included within the system is and a filament engagement device that includes a pathway. The pathway has a first configuration and second configuration, wherein a portion of the length of filament is slidable within the pathway when the pathway is in the first configuration and is restricted from sliding when the pathway is in the second configuration.
