Abstract
We measured anchoring spot distances during passive range of motion in normal canine stifles to determine the optimal graft attachment site and stifle joint angle at the time of anchoring in the repair of cranial cruciate ligament (CCL) rupture. The results in the intra-articular methods showed that the minimal change in graft length was recorded when placing drill holes that extent from anteromedial portion of normal CCL attachment site of the tibia to posterodorsal portion of normal CCL attachment site of the femur. Among the extra-articular methods, the least amount of change in anchoring spot distance was observed when the graft attachment site was placed from the lateral fabella to the proximal tibial tuberosity. Also the stifle joint must be extended at the time of anchoring when using the extra-articular method.
