“…Based on the available footprint dataset, our observations indicated that half of femoral CrCL footprints manifest an arrowhead shape, aligning with previous reports that have documented the presence of this particular shape at the femoral CrCL footprints 15 , 26 . A similar shape was also observable at the tibial site (Fig.…”

“…The procedure for establishing the dataset in the study was inspired by the work of Pillet et al 14 , who conducted a similar experimental approach to quantitatively extract the endpoints of human knee ligaments. In contrast to previous methodologies that focused on estimating footprint centroid positions 12 , 14 , 15 , we developed an SSM-based prediction method that directly estimates footprint contours based on individual bone shapes. This is achieved by propagating the changes in bone shapes to the deformation and positional adjustments of the ligament footprint contours.…”

“…Various methods have been proposed to quantify or mark ligament footprints, including using an optical tracking system 24 , identifying footprints in MR images 12 , and marking footprints with wires 15 and radio-opaque panting 14 before CT scanning. While the optical tracking system allows for accurate recording of footprint locations by precisely pointing to the target positions, extracting the complete bone shapes along with the footprint information can be challenging, particularly when the soft tissues are not entirely removed.…”

Knowledge regarding the ligament footprints in the canine stifle is essential for biomechanical modeling of the joint and patient-specific surgical planning for anatomical ligament reconstruction. The present study aimed to establish and evaluate deformable shape templates (DSTs) of the femur and tibia with footprints of the cruciate and collateral ligaments embedded for the noninvasive estimation of ligament footprint positions. To this end, a data set of computed tomography (CT)-derived surface models of the femur and tibia were established and used to build statistical shape models (SSMs). The contours of the stifle ligaments were obtained from CT scans of 27 hindlimb specimens with radio-opaque markings on the ligament footprints. The DST, constructed by embedding averaged footprint contours into the SSM, was used to estimate subject-specific ligament footprints in a leave-one-out cross-validation framework. The DST predictions were compared with those derived from radio-opaque-marked footprints. The results showed that the averaged Euclidean distances between the estimated and reference footprint centroids were less than 1.2 mm for the cruciate ligaments and 2.0 mm for the collateral ligaments. The DST appeared to provide a feasible alternative approach for noninvasively estimating the footprints of the stifle ligaments in vivo.

“…In the dog, insertions of the CCL on the femur and tibia have been assumed to be isometric, reduced to a single point, and projected onto the lateral aspect of the stifle to identify isometric points for both intracapsular 34 and extracapsular repair 35 of the ruptured CCL. In humans, cadaveric studies using various techniques in intact and anterior cruciate ligament deficient knees have concluded that no two points are absolutely isometric; however, near isometry can be defined within certain limits.…”

Objective The aim of this study was to develop a three-dimensional (3D) model to identify the isometric component of the cranial cruciate ligament (CCL) in dogs. Methods A static 3D model of the specimen was generated from a computed tomography scan of the stifle of a dog and a kinematic model was generated from data collected, every 5 degrees from full extension (131 degrees) through 80 degrees of stifle flexion, from four sensors attached to the tibia. Kinematic data were superimposed on the static model by aligning the points of interest, which were defined for both models. This allowed the tibia to rotate and translate relative to the femur based on the kinematic data. The contours of the distal femur and proximal tibia were converted into point clouds and the distance between each point in the femoral point cloud and all the points in the tibial point cloud were measured at each of the 15 positions. The difference between the maximum and minimum distances for each pair of points was calculated, and when it was less than 0.2 mm, points were illustrated as two red dots connected by a line at their locations on the femur and tibia. Results A total of 3,681 pairs of isometric points were identified and were located at the origin and insertion of the CCL and on the lateral aspect of the stifle. Conclusion Isometric areas are present at the origin and insertion of the CCL and lateral aspect of the stifle. Better understanding of these locations may lead to refinements in techniques to replace the ruptured CCL.

Objective The aim of this study was to investigate detailed functional anatomy of the craniomedial bundle (CrMB) and caudolateral bundle (CdLB) of cranial cruciate ligament (CrCL) for application of intra-articular anatomical reconstruction in dogs. Materials and Methods Twelve stifle joint of 12 Beagle cadavers were used. Anatomical characteristics of femoral attachment regions of the CrCL were determined. Then, the location and area of the footprints of the CrMB and CdLB were objectively measured. Each bundle was equally divided into four fibre bundles, and changes in the fibre arrangement were recorded during stifle range of motion. Additionally, the tension of each fibre bundle at various stifle joint angles was objectively measured. Results The attachment region of the CrCL clearly differed from that reported in humans. The centre of the CdLB attachment site was located craniodistal to that of the CrMB on the femur and slightly caudal to that of the CrMB on the tibia. The area of the CrMB on the femoral and tibial attachment sites was larger than that of the CdLB. During stifle range of motion, each divided fibre bundle in the CrMB and CdLB was twisted intricately. The tension of the CrMB was higher than that of CdLB. The central part of the CrMB was always tense during stifle range of motion. Clinical Significance These results may contribute to the application of anatomical reconstruction surgery for CrCL deficient stifle in dogs.
