Method and apparatus for tibial fixation of an ACL graft

摘要

A tensioner system for use in tensioning graft strands in a knee reconstruction procedure can include a handle assembly, a tensioner assembly coupled relative to the handle assembly, and a drive shaft slidably received through and supported by the handle assembly. The tensioner assembly can include an arm support member rotatably coupled to the handle assembly and first and second arm members each rotatably coupled to lateral sides of the arm support member. Each arm member can include at least one graft attachment area adapted to be coupled to a graft strand. The arm support member can be configured to rotate about an axis perpendicular to a longitudinal axis of the tensioner system and perpendicular to an axis of rotation of each of the arm members. The drive shaft can include proximal and distal ends that extend beyond respective proximal and distal ends of the handle assembly.

1. A method for use in graft fixation in a knee reconstruction procedure, comprising:
forming a femoral tunnel in a femur and a tibial tunnel in a tibia, the femoral tunnel having an opening adjacent a joint space between the femur and the tibia, and the tibial tunnel having an entrance at the joint space and an opposite exit spaced apart from the joint space; positioning a graft into the femoral tunnel and retaining the graft relative to the femoral tunnel; passing the graft though the tibial tunnel such that the graft extends beyond the exit of the tibial tunnel; coupling the graft to a tensioner device, including coupling a first and a second graft strand to a first tensioning arm of the tensioner device and coupling a third and a fourth graft strand to a second tensioning arm of the tensioning device, the first, second, third and fourth graft strands spaced apart from each other when coupled to the respective first and second tensioning arms; positioning a bone engaging member of the tensioner device relative to the tibial tunnel; and tensioning the graft by moving a portion of the tensioner device away from the bone engaging member.
