The standard for graft preparation, now more versatile than ever When Smith & Nephew introduced the original ACUFEX GRAFTMASTER Graft Preparation System in 1995, surgeons found it invaluable for preparing cruciate grafts. Built for single-bundle, double-bundle and bone-tendon-bone (BTB) repairs, it is also designed to work with our family of ENDOBUTTON fixation devices, which provide simple fixation solutions for even the most difficult ACL reconstructions.
