The endoscopic technique offers the advantage of one incision and a fe
moral osseous tunnel trajectory that is more in line with the collagen
fibers of the graft. Technically, it is more demanding to reproducibl
y obtain the interference fixation than using the two-incision techniq
ue. There is a tendency for screw and graft divergence in the femoral
tunnel. The exact clinical significance of this screw and bone plug di
vergence has yet to be clarified. Surgeons must assess their ability t
o obtain the best results for the patient. There is a definite learnin
g curve for the endoscopic technique. We believe that, with further ad
vances in instrumentation, fixation, alternative grafts, it will event
ually be the approach of preference for ACL reconstructions.
