Abstract
Apparatus for tensioning a ligament graft includes a hydraulic tensioning cylinder with a piston having a distal end for holding and affixing, relative to the distal end of the piston, a free end of a ligament graft, where the other end of the ligament graft is affixed to a patient. An inflation device, in hydraulic communication with a cylinder, moves the piston to tension the graft.
