Abstract
To determine the relation between the tunnel positions and the kinematic improvement of
the knee joint after single-bundle (SB) and double-bundle (DB) anterior cruciate ligament (ACL)
reconstructions. Methods: The study included 42 patients who underwent either SB (n 21) or DB
(n 21) ACL reconstruction using hamstring tendon autograft. Anterior tibial translation and
rotational laxity were measured by a navigation system before and after graft fixation. Threedimensional
computed tomography measurement was conducted for evaluation of tunnel placements.
Regression analysis was carried out to determine the association between the postoperative kinematic
change and the tunnel position. Results: The average tunnel location was mostly different between
the SB and posterolateral bundle (PLB) tunnels, as well as between the anteromedial bundle (AMB)
and PLB tunnels of DB ACL reconstructions, whereas the SB and AMB tunnels were similar in the
tibial mediolateral and femoral deep-shallow positions. A regression curve showed that the PLB
femoral tunnel position was correlated with rotation whereas both the SB and AMB femoral tunnel
locations were mostly correlated with anterior tibial translation. Conclusions: The PLB tunnel
location in DB ACL reconstruction had a considerable effect on rotational laxity, whereas the SB and
AMB tunnel locations mostly influenced anterior tibial translation. Level of Evidence: Level III,
case-control study.
