- W2595983005 abstract "Abstract Background Calcium phosphate (CaP)-hybridized tendon grafts improved biomechanical function compared with untreated grafts after single-bundle (SB) anterior cruciate ligament (ACL) reconstruction. The purpose of this study was to compare the biomechanical function between anatomic double-bundle (DB) and single-bundle (SB) ACL reconstructions using CaP-hybridized tendon grafts at 6 months postoperatively in goats. Hypothesis We hypothesized that the postoperative biomechanical function in the DB group is better than that in the SB group. Materials and methods Knee kinematics and in situ forces in the grafts under applied anterior tibial load of 50 N (ATL) and internal tibial torque (ITT) of 2,0 Nm at full extension, and 60° and 90° of knee flexion, and the histology of the tendon-bone interface were compared between the DB group ( n = 6) and SB group ( n = 6). Results The in situ forces under ATL in the DB group at full extension and 90° of knee flexion were greater than those in the SB group. The in situ forces under ITT in the DB group at full extension and 60° of knee flexion were greater than those in the SB group. The in situ forces on the posterolateral bundle of the grafts under ATL and ITT in the DB group at full knee extension were greater than those on the posterior half of the grafts in the SB group. The histology did not differ significantly between the groups. Conclusions Although CaP-hybridized tendon grafts were used in both groups, the in situ forces under ATL and ITT in the DB group were greater than those in the SB group at 6 months postoperatively. The posterolateral bundle of the grafts in the DB group acted effectively against both ATL and ITT at full extension. The tendon-to-bone healing was similar in the both groups.
