The aim of this study was to describe the characteristics and long-term outcome of surgically and conservatively treated cats with cranial cruciate ligament disease (CCLD).
A retrospective cohort study of cats with CCLD, diagnosed at two university animal hospitals between January 2011 and December 2016, was performed. Signalment, history, treatment and follow-up information were retrieved. Cat owners were contacted for additional long-term follow-up information. The cases were divided into two groups: one conservatively managed and one surgically treated with the lateral fabellotibial suture technique. A quality of life questionnaire, the Feline Musculoskeletal Pain Index (FMPI), was distributed to the owners of cats alive at follow-up for assessment of chronic pain as a long-term outcome. Univariable statistical methods were used to evaluate the data.
Fifty cats were identified and were followed for a median of 41 months after diagnosis of CCLD. Seven cats (14%) developed bilateral CCLD. Twenty-eight cats (56%) were treated conservatively and 22 (44%) surgically. All surgically treated cats in which arthrotomy was performed (19/22) had total cranial cruciate ligament rupture and 9/19 (47%) had meniscal injuries. Postoperative surgical complications were recorded in 6/22 cats (27%). Owners of 24/29 (83%) cats still alive at follow-up completed the FMPI questionnaire. The conservatively treated cats had a lower FMPI score, indicating less chronic pain, than those cats treated surgically ( = 0.017).
Conservatively treated cats with CCLD experienced less chronic pain at long-term follow-up than surgically treated cats. Bilateral disease is not uncommon in cats with CCLD.
本研究旨在描述手术和保守治疗猫十字韧带断裂（CCLD）的特征和长期结果。
对 2011 年 1 月至 2016 年 12 月在两所大学动物医院诊断为 CCLD 的猫进行回顾性队列研究。检索了特征、病史、治疗和随访信息。联系了猫主人以获取额外的长期随访信息。将病例分为两组：一组保守治疗，一组采用外侧跖骨-胫骨缝合技术手术治疗。为评估慢性疼痛作为长期结果，向存活的猫主人发放了生活质量问卷，即猫肌肉骨骼疼痛指数（FMPI）。采用单变量统计方法评估数据。
共确定了 50 只猫，在诊断为 CCLD 后中位数随访 41 个月。7 只猫（14%）患有双侧 CCLD。28 只猫（56%）接受保守治疗，22 只（44%）接受手术治疗。所有接受关节切开术的手术治疗猫（19/22）均有完全的十字韧带断裂，9/19（47%）有半月板损伤。22 只手术治疗猫中有 6 只（27%）记录到术后手术并发症。在 29 只仍存活的猫中，24 只（83%）的主人完成了 FMPI 问卷调查。与手术治疗的猫相比，保守治疗的猫在长期随访时的 FMPI 评分较低，表明慢性疼痛较轻（ = 0.017）。
在长期随访中，保守治疗的 CCLD 猫比手术治疗的猫慢性疼痛程度较低。双侧疾病在 CCLD 猫中并不少见。
