A system for use in reconstructing a ligament is provided. The system includes a graft ligament support block and an installation tool. The support block includes a body having a distal and proximal ends and a longitudinal axis extending therebetween, the proximal end being tapered so as to facilitate withdrawal of the support block through a bone tunnel, a graft hole extending through the body transverse to the longitudinal axis and configured to receive a graft ligament therein and a transverse fixation pin hole extending through the body transverse to the longitudinal axis and configured to receive a transverse fixation pin therein. The installation tool includes a holder having a shaft with distal and proximal ends and longitudinal axis extending therebetween, the proximal end of the shaft including at least one finger for engagement in the opening and a handle mounted to the proximal end of the shaft.
