Abstract
The goal of ACL reconstruction surgery is to restore normal ligament function and knee kinematics. Multiple factors can contribute to its outcome. Studies using cadaveric knees have been conducted to examine the effect of surgical variables on ACL reconstruction (1–3,7). However, large inter-specimen variability, less-than-reproducible surgical techniques, difficulties in data collection, and so on have made it difficult to determine the effect of these surgical variables independently. In this study, we studied the effect of knee positioning during ACL reconstruction on in-situ graft force and anterior tibia displacement of the knee when subjected to anterior tibial load. We hypothesize that a robot-assisted positioning of a knee to its initial/intact state should result in better outcomes (5) when compared with the conventional (empirical) positioning by a surgeon.
