Abstract

Objective The aim of this study was to report the prevalence and risk factors of bilateral meniscal tears during a tibial plateau levelling osteotomy (TPLO).

Methods Data from 362 dogs that underwent staged or simultaneous TPLO between January 2006 and April 2019 were retrospectively collected. Variables such as breed, sex, weight change and intervals between surgeries were analysed with logistic regression. Preoperative tibial plateau angle, age, cranial cruciate ligament status and body weight were analysed with a generalized linear mixed model. All analyses were performed to assess the likelihood of bilateral meniscal tears versus unilateral tears and no tears. Correlation of meniscal tears between stifles was assessed with Cohen's kappa coefficient.

Results Prevalence of bilateral meniscal tears was 48.0% (95% confidence interval [CI]: 43.0–53.0%). There was moderate agreement of the presence of meniscal tears between stifles (Cohen's kappa coefficient = 0.41, 95% CI: 0.31–0.51).The odds for bilateral meniscal tears were higher for Rottweilers (odds ratio [OR:] 4.5 [95% CI 1.1–30.3], p = 0.033), older dogs (OR: 1.2 [95% CI: 1.1–1.4 per year], p < 0.0001), smaller dogs (OR: 0.98 [95% CI: 0.97–0.99 per 0.45-kg], p = 0.001), stifles with complete cranial cruciate ligament tears (OR: 21.1 [95% CI: 7.1–62.4], p < 0.0001).

Conclusion Contralateral meniscal tears, breed, older age, lower patient weight and complete cranial cruciate ligament tear were significant risk factors for bilateral meniscal tears. Surgeons can use these results to determine prognoses and propensities for meniscal tears in at-risk dogs.

通过胫骨平台整平截骨术治疗犬颅交叉韧带疾病期间确定的双侧半月板撕裂的患病率和危险因素

摘要

目的 本研究的目的是报告胫骨平台水平截骨术 (TPLO) 期间双侧半月板撕裂的患病率和危险因素。

方法 回顾性收集 2006 年 1 月至 2019 年 4 月期间接受分期或同步 TPLO 的 362 只犬的数据。用逻辑回归分析诸如品种、性别、体重变化和手术间隔等变量。采用广义线性混合模型分析术前胫骨平台角、年龄、颅交叉韧带状态和体重。进行所有分析以评估双侧半月板撕裂与单侧撕裂和无撕裂的可能性。膝关节之间半月板撕裂的相关性用 Cohen 的 kappa 系数进行评估。

结果 双侧半月板撕裂的患病率为 48.0%（95% 置信区间 [CI]：43.0-53.0%）。膝关节之间半月板撕裂存在中等一致性（Cohen's kappa 系数 = 0.41，95% CI：0.31–0.51）。罗威纳犬双侧半月板撕裂的几率更高（优势比 [OR:] 4.5 [95% CI] 1.1-30.3]，p  = 0.033），老年犬（OR：1.2 [95% CI：每年 1.1-1.4]，p  < 0.0001），小型犬（OR：0.98 [95% CI：0.97-0.99 每 0.45- kg]，p  = 0.001），窒息伴颅交叉韧带完全撕裂（OR：21.1 [95% CI：7.1–62.4]，p  < 0.0001）。

结论 对侧半月板撕裂、品种、年龄较大、患者体重较轻、颅交叉韧带撕裂是双侧半月板撕裂的重要危险因素。外科医生可以使用这些结果来确定高危犬半月板撕裂的预后和倾向。
