“…Navigation was thought to be the solution that would help to conduct more anatomical ACL reconstructions also with the double-bundle method. Endele et al [50] conducted a study, in which they compared computer navigation with a free-hand technique in a single-bundle ACL reconstruction. There was no statistical difference between these groups at the two-year follow-up and the conclusion was that manual surgery is as good as computer-aided ACL reconstruction, at least in the hands of an experienced orthopaedic surgeon.…”

Purpose Anterior cruciate ligament (ACL) reconstruction has been under intensive discussion and debate, although the anatomy of this ligament was resolved thoroughly almost 200 years ago. The ACL consist of two bundles, anteromedial (AM) and posterolateral (PL). The conventional single-bundle method reconstructs the AM bundle only, while the modern double-bundle technique recreates both bundles for their anatomical sites. Methods An English language literature search was undertaken over the years 2000-2012 for ACL reconstruction, double-bundle versus single bundle technique. The search found 14 RCTs and two meta-analyses published to date. Results Two of the 14 studies (14 %) showed no difference between the two reconstruction methods while the remaining majority (12 trials, 86 %) concluded that the DB technique was better than the SB method. After the DB reconstruction, rotational stability of the knee was better in seven studies (50 %) and anteroposterior stability in six (43 %). No study spoke for the single-bundle technique. In addition, with the double-bundle technique knee scores were reported to be better in five (36 %) studies, and three trials (21 %) revealed less reoperations in the double-bundle group. Conclusions The double-bundle ACL reconstruction technique was reported to have better or at least the same results as the conventional single-bundle method-even at a fiveyear follow-up. However, the majority of these studies had a rather short follow-up, and thus, longer studies are needed to confirm the true long-term results of ACL surgery. Long follow-up periods are also needed to find out whether double-bundle ACL reconstruction can eventually prevent knee osteoarthritis.

“…1 Treatment of ACL injuries has advanced a great deal since the 1960s, when Slocum and Larson 2 attempted periarticular control for ACL repair. It is estimated that ACL injuries affect more than 175,000 patients annually; approximately 38,000 of these patients are high school age.…”

“…The annual cost for ACL repair is approaching $1 billion. 1 Treatment of ACL injuries has advanced a great deal since the 1960s, when Slocum and Larson 2 attempted periarticular control for ACL repair. Subsequent research, however, has shown that periarticular control and direct ACL reattachment do not work to repair ACL injuries.…”

Anterior cruciate ligament (ACL) injuries affect more than 175,000 patients annually. Located in the center of the knee joint, the ACL is the major stabilizing ligament of the knee. If the ACL is injured, then the knee becomes unstable and can buckle when the person pivots. Surgeons can use autograft or allograft tissue to accomplish ACL reconstruction by using a single-bundle or double-bundle type of repair. The surgeon performs the reconstruction arthroscopically, using two ports and a small incision over the anteromedial surface of the tibia to facilitate passage of the graft and for distal fixation of the graft. Correct placement of the tibial and femoral tunnels is the most important technical aspect of the procedure. After reconstruction, the patient must undergo intense physical therapy starting one or two days after surgery. If diligent with physical therapy, then the patient can return to full activity as soon as four months after surgery.

“…It has been estimated that nearly 175,000 ACL reconstructions are performed each year, with an estimated cost of up to $1 billion [1][2][3][4]. Despite generally good outcomes after ACL surgery, research continues into ways of preventing post-reconstruction problems such as the need for ACL revision reconstruction or the development of osteoarthritis.…”

Objective: To develop and evaluate the feasibility and reliability of an alternative three-dimensional (3D) measurement system capable of characterizing tunnel position and orientation in ACL reconstructed knees. Methods: We developed a surgically oriented 3D measurement system for characterizing femoral and tibial drill tunnels from ACL reconstructions. This is accomplished by simulating the positioning of the drill bit originally used to create the tunnels within the bone, which allows for angular and spatial descriptions along defined axes that are established with respect to previously described anatomic landmarks and radiographic views. Computer-generated digital phantoms composed of simplified geometries were used to verify proper calculation of angular and spatial measurements. We also evaluated the inter-observer reliability of the measurements using 10 surfaces generated from cadaveric knees in which ACL tunnels were drilled. The reliability of the measurements was evaluated by intraclass correlation coefficients. Results: The digital phantom evaluation verified the measurement methods by computing angular and spatial values that matched the known values in all cases. The intraclass correlation coefficient was calculated for four users and was found to range from 0.95 to 0.99 for the femoral and tibial measurements, demonstrating near-perfect agreement. Conclusions: The characterization of ACL tunnels has historically concentrated on two-dimensional (2D) measurements; however, it can be difficult to define ACL tunnel placement using 2D methods. We have presented novel techniques for defining graft tunnel placement from 3D surface representations of the ACL reconstructed knee. These measurements provide exact tunnel location spatially and along axes that offer the potential to comparatively analyze ACL reconstructions post-operatively using advanced imaging. These methods are reliable, and have been demonstrated to be applicable to multiple single-bundle techniques for ACL reconstruction.
