Abstract

Objectives: To identify dogs at risk of developing pivot-shift (PS) following tibial-plateau-leveling-osteotomy (TPLO) using a rotational-instability-test (RI-test), describe a combination of a monofilament anti-rotational suture (ARS) with TPLO and assess this technique for feasibility, compare post-operative PS-incidence in dogs receiving a standard TPLO (TPLO-only) or a TPLO with ARS (TPLO+ARS), and design a novel TPLO-plate facilitating ARS-anchoring (TPLO/ARS-plate).

Study design: In this clinical pilot trial on 85 client-owned dogs and instrumentation design study, the RI-test and ARS-placement-technique were described and performed. Reporting included: anesthesia and surgery times, bone-healing, post-TPLO-PS-incidence, follow-up and complications. Significance was set as p ≤ 0.05. Comprehensive engineering of a novel TPLO plate was performed.

Results: Between TPLO-only (n = 57) and TPLO+ARS (n = 28) groups, significant differences were found for surgery time (p = 0.01), anesthesia time (p<0.001) and bone healing scores (p = 0.03), all being longer/higher for TPLO+ARS. PS-incidence was 2/57 (TPLO-only) and 0/28 (TPLO+ARS) within the first 8 weeks post-surgery (p = 1.00). Medium follow-up was 642 days. Major complications during that time occurred in 2/57 (TPLO-only; infection and implant removal) and 1/28 (TPLO+ARS; infection, PS-development and implant removal) dogs (p = 1.00). A novel TPLO/ARS-plate was designed.

Conclusion: Post-TPLO-PS might be reduced following ARS placement. Additional studies are indicated to validate and refine the RI-test and assess the novel TPLO/ARS-plate in the clinical setting.

单丝防旋转缝合联合TPLO防止枢轴移位：手术技术及新型TPLO钢板设计。

目的：通过旋转不稳定性测试（RI-test）识别胫骨-平台水平截骨术（TPLO）后发生支点移位（PS）风险的犬，描述单丝防旋转缝合（ARS）与TPLO的组合并评估该技术的可行性，比较接受标准TPLO （TPLO-only）或TPLO与ARS （TPLO+ARS）的犬术后PS的发生率，并设计一种新型TPLO-plate促进ARS锚定（TPLO/ARS-plate）。研究设计：在85只客户拥有的狗的临床试验和仪器设计研究中，描述并执行了ri测试和ars放置技术。报告内容包括：麻醉和手术时间、骨愈合、tplo - ps术后发生率、随访和并发症。p ≤ 0.05为显著性。对一种新型TPLO板进行了综合工程设计。结果：单纯TPLO组（n = 57）与TPLO+ARS组（n = 28）在手术时间（p = 0.01）、麻醉时间（pp = 0.03）上差异有统计学意义，TPLO+ARS组均更长/更高。术后前8周 内，ps发生率分别为2/57（仅TPLO）和0/28 (TPLO+ARS) （p = 1.00）。中期随访时间为642 天。主要并发症发生在2/57（仅TPLO；感染和植入物移除）和1/28 （TPLO+ARS；感染、ps发育和植入物移除）犬中（p = 1.00）。设计了一种新型TPLO/ ars板。结论：置放ARS后tplo - ps可能减少。需要进一步的研究来验证和完善ri测试，并在临床环境中评估新型TPLO/ ars钢板。

期刊介绍： Frontiers in Veterinary Science is a global, peer-reviewed, Open Access journal that bridges animal and human health, brings a comparative approach to medical and surgical challenges, and advances innovative biotechnology and therapy. Veterinary research today is interdisciplinary, collaborative, and socially relevant, transforming how we understand and investigate animal health and disease. Fundamental research in emerging infectious diseases, predictive genomics, stem cell therapy, and translational modelling is grounded within the integrative social context of public and environmental health, wildlife conservation, novel biomarkers, societal well-being, and cutting-edge clinical practice and specialization. Frontiers in Veterinary Science brings a 21st-century approach—networked, collaborative, and Open Access—to communicate this progress and innovation to both the specialist and to the wider audience of readers in the field. Frontiers in Veterinary Science publishes articles on outstanding discoveries across a wide spectrum of translational, foundational, and clinical research. The journal''s mission is to bring all relevant veterinary sciences together on a single platform with the goal of improving animal and human health.
