The ABS has revolutionized tibial fixation of ACL and PCL grafts used in knee
ligament surgery.
ABS loops can be used on all graft types and attached to a
variety of button configurations for fixation over sockets created with a drill or full
tunnels with concave buttons. The flat-tape ABS loop improves handling
characteristics and is designed to reduce graft abrasion.
The two-piece ABS implant easily passes through narrow bone tunnels and
allows increased cortical fixation with the assembly of a large button over the
cortical bone. Use the ABS for tibial fixation during all-inside ACL reconstruction
using graft fixation over tunnels created during transtibial ACL reconstruction.
ABS Button Overview
The advantages of the ABS implant
include:
■ Strong, reliable cortical fixation superior to
interference screws1
■ Maximum graft-to-bone contact improves
incorporation and healing2
■ Retension grafts after fixation and knee cycling
■ Several different button options for sockets and
full tunnels
■ Seal off tibial tunnel to preserve blood and growth
factors in tibial tunnel
Concave ABS Buttons
Ideal for both sockets and full tunnel applications (14
mm and 20 mm buttons). The centering feature of these
buttons maintains position over the tunnel and provides
a better seal at the cortex than standard flat buttons. The
concave surface countersinks sutures and knots. The 14
mm and 20 mm buttons have slots for the implant loop
along with two holes for additional sutures.
