The first aim of this study was to examine whether or not variations concerning the conformational characteristics of the proximal surface of the tibial plateau exist among six different dog breeds as well as within the same breed. The second aim of this study was to determine the coordinates of the cruciate ligaments.
One hundred and four tibias of 52 mature dogs from six different breeds were used. Photographs of the proximal surface of tibial plateau were taken, and measurements for the length, width and area of the tibial plateau, and the lateral and medial condyles were taken. In addition, the intercondylar width, height of Gerdy's tubercle, popliteal notch depth, and extensor groove depth were measured and recorded. The quotients from these measurements were calculated and compared amongst the dog breeds. The coordinates of the cruciate ligaments, according to the centre of tibial plateau, were also determined.
Based on the calculated quotients, variations in the geometry of the tibial plateau geometry were common among the breeds. Within the same breed, on the other hand, length and width measurements of the tibial plateau were the least variable parameters among the other parameters examined. The cranial cruciate ligament was located in front of the surface centre of tibial plateau in all breeds. The position of cranial cruciate ligament was more variable in the craniocaudal direction than that observed in the mediolateral direction; this was the exact opposite of caudal cruciate ligament.
The inter-breed variations of the quotients determined in the present study may facilitate attempts aimed to assess the risk factors of stifle joint injury and to design total knee prostheses.
本研究的首要目的是检查六种不同犬种之间以及同一犬种内胫骨平台近端表面的构象特征是否存在差异。本研究的第二个目的是确定十字韧带的坐标。
使用了来自六个不同犬种的52只成年犬的104根胫骨。拍摄胫骨平台近端表面的照片，并对胫骨平台、外侧和内侧髁的长度、宽度和面积进行测量。此外，测量并记录髁间宽度、Gerdy结节高度、腘窝切迹深度和伸肌沟深度。计算这些测量值的商，并在犬种之间进行比较。还根据胫骨平台中心确定了十字韧带的坐标。
根据计算出的商，胫骨平台几何形状的变化在不同犬种中很常见。另一方面，在同一犬种内，胫骨平台的长度和宽度测量值是所检查的其他参数中变化最小的参数。所有犬种的前交叉韧带均位于胫骨平台表面中心的前方。前交叉韧带在头尾方向上的位置比在内外侧方向上的变化更大；这与后交叉韧带正好相反。
本研究中确定的商的品种间差异可能有助于评估 stifle 关节损伤的危险因素和设计全膝关节假体的尝试。
