Intraoperative comparisons of knee kinematics of double-bundle versus single-bundle anterior cruciate ligament reconstruction

Abstract

II.

Can the pivot-shift be eliminated by anatomic double-bundle anterior cruciate ligament reconstruction?

“…The value of the PS was calculated from the values of the maximum rotation and AP translation obtained when performing the maneuver [12,16,29,30,40].…”

Double-bundle revision anterior cruciate ligament reconstruction is effective in rescuing failed primary reconstruction and re-introducing patients to physical exercise

“…Although revision ACL reconstruction is promising, the outcome is generally inferior to that of successful primary ACL reconstruction (9,26). Despite double-bundle ACL reconstruction producing superior clinical outcomes to those of single-bundle ACL reconstruction (16)(17)(18)(19)(20)(21)(22)(23)(24), the double-bundle technique has rarely been used in revision ACL reconstruction due to it being technically more challenging (27). Tunnel placement errors, particularly femoral tunnel misplacement, are the most common causes for primary graft failure (28).…”

“…Compared with single-bundle ACL reconstruction, the double-bundle technique produced better Lachman and pivot-shift test results, KT arthrometry results and Tegner score after 3-12 years post operation (19). In most cases, double-bundle ACL reconstruction yielded significantly favorable results on KT arthrometry, pivot shift test and Lachman test (16)(17)(18)(19)(20)(21)(22)(23)(24), as well as reduced graft failure (22)(23)(24) and improved International Knee Documentation Committee (IKDC) objective score (18,23,24) compared with single-bundle ACL reconstruction. Therefore, double-bundle ACL reconstruction is indicated to be superior to single-bundle ACL reconstruction.…”

“…Consequently, inferior outcomes to primary ACL reconstructions were reported, although significant improvements have been demonstrated after revision reconstruction (10)(11)(12)(13)(14). Of note, most revision ACL constructions were performed using a single-bundle technique (15); however, a vast amount of evidence has demonstrated that the double-bundle technique is superior to the single-bundle technique for primary ACL reconstruction (16)(17)(18)(19)(20)(21)(22)(23)(24). Compared with single-bundle ACL reconstruction, the double-bundle technique produced better Lachman and pivot-shift test results, KT arthrometry results and Tegner score after 3-12 years post operation (19).…”

Partial Anterior Cruciate Ligament Ruptures: Knee Laxity Measurements and Pivot Shift

“…Its use in evaluating knee kinematics and laxity is also valuable. It can provide valuable data on anteroposterior translation and internal and external rotation (Plaweski et al 2011). This invasive method requires two rigid bodies attached to pins inserted in the distal femur and proximal tibia to provide an intraoperative 3D anatomic model of the patient's knee surface geometry.…”
