ABSTRACT:
A graft ligament strand tensioner includes a frame member for slidingly retaining loops of sutures extending from graft ligament strands. The tensioner further includes a collar portion, and is provided with a handle having a core portion on which the collar portion is disposed for axial movement, and a grip portion. The tensioner still further includes a spherical member connected to the handle and having rounded surfaces facing the collar portion. The collar portion is tiltingly movable on the spherical member rounded surfaces when manipulation of the handle, to pull sutures on the frame member taut, causes the collar portion to engage the spherical member rounded surfaces. The sliding retention of the sutures and the tilting movement of the collar portion provide substantial equalization of tension in the sutures and thereby the graft ligament strands.
