Abstract

Objective The aim of this study was to investigate the prevalence of cranial cruciate ligament rupture and patellar luxation and the associated risk factors in dogs.

Materials and Methods A total of 13,072 clinical records of dogs were reviewed from School Hospital (Faculty of Veterinary Sciences, National University of La Plata). Data of age, breed, sex, body weight, patellar luxation and cranial cruciate ligament rupture condition were registered. Chi-squared and Fisher's exact tests were used to compare the prevalence of cranial cruciate ligament rupture and patellar luxation with the variables and then univariable logistic regression was used to evaluate the risk of having cranial cruciate ligament rupture and patellar luxation. Multivariable logistic regression was used including all variables to assess the odds of having patellar luxation and cranial cruciate ligament rupture.

Results Of 13,072 patients treated, 72 and 51 had cranial cruciate ligament rupture and patellar luxation respectively. Sex was not a major risk factor for either condition. Adult (odds ratio [OR] = 8.2) and senior (OR = 4.3) patients had increased risk of having cranial cruciate ligament rupture, while for patellar luxation age was not a risk factor. Groups 2, 3 and 8 were more likely to have cranial cruciate ligament rupture (OR = 5.5, OR = 9.1 and OR = 2.6), and group 11 had lower risk of having patellar luxation (OR = 0.08). Maxi (OR = 2.4) and giant (OR = 6.0) breeds had higher risk of having cranial cruciate ligament rupture, and medium and maxi breeds had higher risk of patellar luxation (OR = 0.05 and OR = 0.3). Multivariate OR test confirmed that age (adult), body size (giant and maxi) and breed group (Group 3) were significantly associated with having cranial cruciate ligament rupture, and age was associated with having patellar luxation.

Clinical Significance This is the first epidemiological study of cranial cruciate ligament rupture and patellar luxation in dogs from School Hospital (Faculty of Veterinary Sciences, National University of La Plata). Giant and large adult dogs from the Molossoid and Terrier breeds were more likely to have cranial cruciate ligament rupture, while mixed and large dog breeds showed the lowest risk of having patellar luxation.

阿根廷布宜诺斯艾利斯省犬颅十字韧带断裂和髌骨脱位的流行病学

摘要

目的本研究的目的是调查犬颅交叉韧带断裂和髌骨脱位的患病率及其相关危险因素。

材料和方法从学校医院（拉普拉塔国立大学兽医学院）审查了总共 13,072 条狗的临床记录。记录年龄、品种、性别、体重、髌骨脱位和颅交叉韧带断裂情况等数据。使用卡方检验和Fisher精确检验将颅交叉韧带断裂和髌骨脱位的发生率与变量进行比较，然后使用单变量logistic回归评估颅交叉韧带断裂和髌骨脱位的风险。使用包括所有变量的多变量逻辑回归来评估髌骨脱位和颅交叉韧带断裂的几率。

结果在接受治疗的 13,072 名患者中，分别有 72 名和 51 名患有颅交叉韧带断裂和髌骨脱位。性别不是这两种情况的主要危险因素。成人（比值比 [OR] = 8.2）和老年（OR = 4.3）患者颅交叉韧带断裂的风险增加，而髌骨脱位年龄不是危险因素。第 2、3 和 8 组更可能发生颅交叉韧带断裂（OR = 5.5，OR = 9.1 和 OR = 2.6），第 11 组发生髌骨脱位的风险较低（OR = 0.08）。Maxi (OR = 2.4) 和巨型 (OR = 6.0) 品种颅交叉韧带断裂的风险较高，中等和 maxi 品种髌骨脱位的风险较高（OR = 0.05 和 OR = 0.3）。多变量 OR 测试证实年龄（成人）、

临床意义这是第一次对来自学校医院（拉普拉塔国立大学兽医学院）犬颅交叉韧带断裂和髌骨脱位的流行病学研究。来自 Molossoid 和 Terrier 品种的巨型和大型成年犬更容易出现颅交叉韧带断裂，而混合犬和大型犬品种的髌骨脱位风险最低。
