Abstract:
1. A tool for implanting a ligament graft in a patient comprising: a handle portion; an elongate member comprising: a proximal end engaged with the handle portion; and a distal end; and at least one attachment member; wherein the at least one attachment member is proximal the distal end of the elongate member, the at least one attachment member is configured to engage a first portion of at least one ligament graft, the distal end of the elongate member is configured to engage a second portion of the at least one ligament graft, wherein a tension force is applied to the at least one ligament graft between the first portion of the at least one ligament graft engaged with the at least one attachment member and the second portion of the at least one ligament graft engaged with the distal end of the elongate member, wherein the elongate member is translatable in the proximal to distal direction to selectively increase and decrease the tension force applied to the at least one ligament graft; a tension member configured to impart a user selectable tension force to the at least one ligament graft within a predetermined range of tension forces, wherein the tension member is a spring, wherein the predetermined range of tension forces is between about zero pounds of tension force and about twenty two pounds of tension force; and a knob configured to rotate in a first direction to increase the tension force applied to the at least one ligament graft and rotate in a second direction to decrease the tension force applied to the at least one ligament graft.
