“…The present study examined the "time 0" (ie, initial) properties of PCL reconstruction using a central third patellar tendon graft. The mean failure load afforded by screw fixation of a central third patellar tendon graft (generally less than 900 N) 5,15,19,21,33 is markedly lower than that of an intact PCL with its native insertion sites (~1600 N for the anterolateral bundle). 31 During our pilot tests, cyclic loading to 250 N resulted in sample failure within 200 test cycles.…”

“…This model has been used in numerous biomechanical studies addressing ligament reconstructions of the knee. 7,[38][39][40][41] Although the bone mineral density is comparable with that of the human distal femora and proximal tibiae, a transfer to the in vivo situation in humans was not thoroughly possible. 42 Nurmi et al 43 showed in their study that porcine tibiae were only a poor substitute for human bone, particularly when interference fixation is used.…”

“…Another limitation of the present study is that specimens were porcine knees. However, in previous studies, porcine knees were used for biomechanical study of the ACL as a substitute for human knee joint because the size of the joint and ACL are similar to human knee (Liu et al, 1995;Maeyama et al, 2011).…”

In the present study, an image correlation method was used to determine the site-dependent strain in the porcine anterior cruciate ligament (ACL). In particular, the strain of the ACL in the femoral and tibial attachment areas was quantified when the eight knees were subjected to a maximum of 50 N anterior tibial load that was applied using a 6-DOF robotic system. The ACL strains in the anterior, central, and posterior bundles of the medial, middle and lateral layers were determined as a function of the applied anterior load. In addition, the surface of the ACL was observed using a light microscope under no loading condition. Results revealed that the strain in the medial layer of the ACL increased gradually and almost linearly with the increase of anterior load in the midsubstance area. In contrast, the strain in the femoral and tibial attachment areas of the medial layer of the ACL increased rapidly at the beginning of anterior loading and gradually thereafter with significant differences in slope of strain-anterior load curve found in the anterior and posterior bundles. The largest strain in response to 50 N of anterior force was found in the tibial attachment area in medial and middle layers, while the maximum strain was found in the femoral attachment area in the lateral layer. Microscopic observation indicated that crimp structure was more clearly observed in the femoral and tibial attachment areas than in the mid-substance. These microstructural features of the ACL were may be attributable to the higher and load-dependent, nonlinear strain observed in the attachment areas. Our study suggested that the strain in the ACL at full extension is site-and load-dependent in a non-linear manner at the femoral and tibial attachment areas.
