Claim:
1. A ligament prosthesis system comprising a ligament prosthesis and an anchor therefor, wherein the anchor is a tubular bone anchor comprising: (a) a longitudinal axis extending from a head at a proximal end of the anchor to a tip at a distal end of the anchor; (b) a central, axial hole extending through the anchor from the head to the tip; (c) a recess located at an exit of the central, axial hole within the head, the recess having a larger diameter than a diameter of the central, axial hole; and (d) a separate ceramic eyelet defining a circular opening, the eyelet being positioned in the recess such that the circular opening communicates with the central, axial hole, and wherein the eyelet has a rounded exit edge, the rounded exit edge having a convexity in a longitudinal direction of the anchor to minimize strain and wear on the ligament prosthesis; and wherein the ligament prosthesis is configured to pass through the central, axial hole of the anchor and the circular opening of the eyelet and comprises a plurality of polymeric fibers.
