Abstract
A soft tissue washer for use with a cancellous screw for attaching soft tissue, such as ligaments, to bone has posts disposed on a distal face of a washer body to limit penetration of sharp pins extending from the distal face into soft tissue, an annular recess disposed is the distal face to receive and clamp soft tissue, recess portions deeper than the annular recess disposed in the distal face to relieve compression of soft tissue, a dished recess in a proximal face of the washer body to entirely receive the head of the cancellous screw such that the head does not protrude from the washer and suture retention passages extending from the dished recess to a lateral rim of the washer for receiving sutures.
