In Korea, small dogs are more common than large breeds. This study was performed to measure the influence of body weight, sex, breed, age, and cranial cruciate ligament rupture (RCCL) on the tibial plateau angle (TPA) in small-breed dogs.
A total of 274 dogs (221 normal dogs and 53 RCCL dogs) were selected for this study based on medical records. The TPA was measured from stifle joint radiographs. The dogs were divided according to body weight, sex (male and female; normal and neutered), age, breed, and RCCL, and the TPAs of the dogs were compared.
In general, the TPAs of male dogs were significantly ( < 0.05) higher than those of female dogs, and those of healthy neutered dogs were higher than those of healthy intact dogs. The TPA had a tendency to increase along with the animal's age but was not significantly different among the four age groups. In general, the TPA of RCCL dogs was 27.12° ± 0.62°, which was significantly higher ( < 0.001) than that of normal dogs (20.21° ± 0.32°), indicating that an increased TPA is associated with a higher risk for RCCL. Similar results were also observed among dogs with similar body weights, breeds, and ages for male and female RCCL dogs.
This study suggested that the sex and neutering status of dogs could affect the TPA. This study also confirmed the use of TPA in the veterinary clinic as a possible indicator of RCCL, as the TPA is higher in RCCL dogs than in normal dogs.
在韩国，小型犬比大型犬更常见。本研究旨在测量体重、性别、品种、年龄和颅交叉韧带断裂（RCCL）对小型犬胫骨平台角（TPA）的影响。
基于病历记录，共选择274只犬（221只正常犬和53只RCCL犬）用于本研究。通过 stifle 关节X光片测量TPA。根据体重、性别（雄性和雌性；正常和绝育）、年龄、品种和RCCL对犬进行分组，并比较犬的TPA。
总体而言，雄性犬的TPA显著（<0.05）高于雌性犬，健康绝育犬的TPA高于健康未绝育犬。TPA有随动物年龄增加的趋势，但在四个年龄组之间无显著差异。总体而言，RCCL犬的TPA为27.12°±0.62°，显著高于正常犬（20.21°±0.32°）（<0.001），表明TPA增加与RCCL风险较高相关。在体重、品种和年龄相似的雄性和雌性RCCL犬中也观察到类似结果。
本研究表明犬的性别和绝育状态可能影响TPA。本研究还证实了在兽医临床中使用TPA作为RCCL的可能指标，因为RCCL犬的TPA高于正常犬。
