Evaluation of a computer-assisted navigation system for anterior cruciate ligament reconstruction: Prospective non-randomized cohort study versus conventional surgery

Abstract

Our results establish the large-scale feasibility of computer-assisted navigation for ACL reconstruction. However, the main outcomes at 1 year showed no significant differences between patients managed with and without computer-assisted navigation.

Current use of navigation system in ACL surgery: a historical review

“…However, there are also manuscripts that do not indicate any improvement in clinical outcome when using navigation systems [15, 29, 116, 123]. Recently, Margier et al [77] in a prospective multicentre open controlled study evaluated 214 patients who underwent ACL reconstruction surgery with and without computer assistance.…”

Clinical advantages of image-free navigation system using surface-based registration in anatomical anterior cruciate ligament reconstruction

“…The usefulness of computer‐assisted ACL reconstruction has been debated, as it requires longer operating times and operating room occupancy [22] and there have been questionable clinical outcomes [2, 27, 34] with the technology. However, previous studies focused on the efficacy of the system and precision of the surgeon, drilling the tunnels.…”

“…However, others have criticized the system because of longer operating times, another operation occupancy, limitations present in the tracking technology on accurate tracking of knee motion with use of rigid osseous fixation of trackers [16], and questionable postoperative clinical outcomes related to conventional surgery [22,27]. There have been many clinically applied ACLR navigation systems developed within the past two decades; however, the surgeons have not obtained up-to-date accuracy and precision even with widely referred navigation systems like OrthoPilot, PRAXIM Medivision, KneeNav™, and Vector-Vision [26].…”

“…Therefore, search for better blood management minimizing blood loss has long been a major question. Intraoperative several aspects can reduce blood loss; the use of tourniquet [13], minimally invasive surgery [11], injection tranexamic acid(TXA) [23,2],computer assisted TKA [18]and drain placement protocols [20]. Methods of postoperative include utilize elastic bandage [4], cryotherapy [10], continuous passive motion(CPM) and postoperative knee position regimens [17].…”
