“…We first attempted to utilize the rabbit and goat animal models for posterolateral knee ligament injuries . Unfortunately, due to the small size of the rabbit and a fused tibiofibular joint in the goat, these were unsuccessful models for study of this injury pattern.…”

Until recently, the posterolateral corner of the knee was noted both for its complex anatomy and diagnostic challenges. To improve the understanding of the posterolateral knee, we completed a comprehensive and stepwise research program with a focus on five primary areas: (1) surgical approach and relevant anatomy; (2) diagnosis; (3) clinically relevant biomechanics; (4) natural history; and (5) surgical treatment. Based on this comprehensive research program, the diagnosis and outcomes following treatment of posterolateral knee injuries have been significantly improved comparing the preoperative state to the state of the knee at a minimum 2 year follow-up in the cases series presented here. ß

“…Anatomic studies on animal knees have been performed to better understand the posterolateral aspect of the human knee. Qualitative and quantitative measurements of the anatomy and biomechanics of this region have been studied in rabbits (Crum et al, ; LaPrade et al, ; LaPrade et al, ), goats (LaPrade et al, ), and more recently, canine knees (Griffith et al, ). Overall, structures of the FCL in rabbits, goats, and canines resemble the human FCL (Crum et al, ; LaPrade et al, ; Griffith et al, ).…”

In addition, a biomechanical study on canine knees has shown that the FCL acts as the primary restraint to varus rotation at all flexion angles (Griffith et al, ), which has also been shown in human knees (Grood et al, ; Nielsen et al, ; Gollehon et al, ; Grood et al, ; Markolf et al, ; LaPrade et al, ; Meister et al, ; Surgita and Amis, 2001; LaPrade et al, ; Ciccone et al, ; Espregueira‐Mendes and da Silva, ; LaPrade, ; Coobs et al, ).…”

“…However, there are some unique anatomical features that are different among canine, rabbit, goat, and human knee structures. In both rabbits and goats, the tibia and fibula are fused together to form a tibiofibula (Crum et al, ; LaPrade et al, ). In rabbits, the fibular head is distal to the lateral tibial plateau surface (Griffith et al, ) and in goats, the fibular head is fused to the proximal edge of the lateral tibial plateau and forms a bony prominence (Crum et al, ).…”

The fibular collateral ligament of the knee

et al. 2013

The fibular collateral ligament (FCL) is one of the larger ligaments of the knee. The FCL, along with the popliteus tendon, arcuate popliteal ligament, and joint capsule, make up the posterolateral corner of the knee. Recently, there has there been an increased awareness and research on the structures of the posterolateral corner of the knee, particularly the FCL. Studying the detailed structure of the FCL may provide a better understanding that can lead to better diagnosis and treatments following injury. Therefore, this article reviews the FCL, which appears to be the primary restraint to varus rotation but is poorly oriented to resist external rotation of the knee.

The purpose of this study was to describe the anatomy and characterize the biomechanics of the posterolateral aspect of the canine knee. Ten adult canine knees were each used for anatomy and biomechanical testing. Distances and motion limits were measured using a 6 degree-of-freedom electromagnetic tracking system. Canine knee dissection reproducibly identified structures present in the human posterolateral knee. The course and attachment sites of the fibular collateral ligament, popliteofibular ligament, and popliteus tendon were similar to human anatomy. Sequential sectioning of the fibular collateral ligament, popliteofibular ligament, and popliteus tendon all significantly increased varus translation at full extension, 60 degrees , and 90 degrees of knee flexion. Sectioning of the fibular collateral ligament significantly increased external rotation at flexion angles near full extension, while popliteus tendon sectioning also significantly increased external rotation at 90 degrees of knee flexion. Based on the fact that the anatomy of the fibular collateral ligament, popliteus tendon, popliteofibular ligament, and the biomechanical properties of the canine posterolateral knee are similar to the human knee, we believe the canine knee is a suitable model to study the natural history of posterolateral knee injuries. The canine model will also prove valuable in the validation of reconstruction techniques and studying the potential development of medial compartment osteoarthritis following posterolateral knee injuries.
