Abstract

Objectives: The aim of the study was to investigate the contact mechanics and kinematic changes in the stifle in different standing angles.

Study design: We performed a biomechanical ex vivo study using pairs of canine cadaver hindlimbs. Motion sensors were fixed to the tibia and the femur for kinematic data acquisition. Pressure mapping sensors were placed between the femur and both menisci. Thirty percent bodyweight was applied to the limbs with the stifle in 125, 135, or 145 degrees of extension.

Results: Stifle flexion angle influences femoromeniscal contact mechanics significantly. The load on both menisci was significantly higher for 125 and 135 degrees in comparison to 145 degrees. Additionally, the center of force was located significantly more caudal when comparing 125 to 145 degrees in the medial meniscus as well as in both menisci combined.

Conclusion: The angle of knee flexion significantly impacts the contact mechanics between the femur and the meniscus. As the knee flexes, the load on both menisci increases.

评估不同屈曲角度下健全犬跗关节的半月板负荷和负荷分布。

研究目的研究目的：研究不同站立角度下跗关节的接触力学和运动学变化：研究设计：我们使用一对犬尸体后肢进行了一项生物力学活体研究。运动传感器固定在胫骨和股骨上，用于采集运动数据。压力绘图传感器被放置在股骨和两个半月板之间。在跗关节伸展125、135或145度时，将30%的体重施加到四肢上：结果：跗关节屈曲角度对股骨半月板接触力学有显著影响。与 145 度相比，125 度和 135 度对两个半月板的负荷明显更高。此外，在内侧半月板和两个半月板的结合部，125 度和 145 度的力中心明显位于尾部：结论：膝关节屈曲角度对股骨和半月板之间的接触力学有重大影响。随着膝关节的屈曲，两个半月板的负荷都会增加。

期刊介绍： Veterinary and Comparative Orthopaedics and Traumatology (VCOT) is the most important single source for clinically relevant information in orthopaedics and neurosurgery available anywhere in the world today. It is unique in that it is truly comparative and there is an unrivalled mix of review articles and basic science amid the information that is immediately clinically relevant in veterinary surgery today.
