OBJECTIVE  The aim of this study was to compare outcomes after tibial plateau levelling osteotomy (TPLO) and modified Maquet procedure (MMP) for the treatment of cranial cruciate ligament rupture (CCLR) in dogs using clinical and radiographic evaluation and treadmill-based force plate gait analysis. STUDY DESIGN  This study was a prospective, randomized, controlled study. MATERIALS AND METHODS  Sixty-one dogs (76 joints) with CCLR were treated with TPLO (n = 30 dogs, 41 joints) or MMP (n = 31 dogs, 35 joints) and compared with a control group of 16 healthy Labrador Retrievers. Outcomes after surgery were compared by clinical orthopaedic assessment, radiographic evaluation and force plate gait analysis performed preoperatively, and then at 6 weeks, 3 and 6 months postoperatively. For objective comparison of ground reaction forces, the data were compared with the control group. Major complications were reported. RESULTS  A significant improvement in ground reaction forces was reached in all surgically treated dogs. No significant difference was found between the surgical methods at any postoperative re-examination. With regard to peak vertical force (PVF), there were significantly more patients with TPLO within the reference range of healthy dogs at the 3 months re-examination than dogs with MMP. There was no significant difference in mean value comparisons between TPLO and control groups 6 months postoperatively. Compared with the control group, mean values of 93.9% (PVF) and 85.9% (vertical impulse [VI]) were reached by the TPLO group and 89.4% (PVF) and 79.9% (VI) by the MMP group, 6 months postoperatively.No significant differences were found regarding major complications or progression of osteoarthritis. CONCLUSIONS  Although no significant differences were found between the surgical methods, TPLO patients showed superiority with regard to clinical outcome.

颅骨十字韧带破裂犬胫骨平台平整截骨术和改良Maquet手术后的结果。

目的本研究的目的是使用临床和放射学评估以及基于跑步机的力板步态比较胫骨平台平整截骨术（TPLO）和改良的Maquet手术（MMP）治疗狗的颅交叉韧带破裂（CCLR）后的结果分析。研究设计该研究是一项前瞻性，随机对照研究。材料与方法用TPLO（n = 30只狗，41个关节）或MMP（n = 31只狗，35个关节）治疗了CCLR的六十一只狗（76个关节），并与对照组的16只健康拉布拉多犬进行了比较。通过术前，术后6周，3个月和6个月的临床骨科评估，影像学评估和测力板步态分析来比较手术后的结果。为了客观比较地面反作用力，将数据与对照组进行比较。据报道主要并发症。结果所有接受手术治疗的狗的地面反作用力均得到了显着改善。在任何术后复查中，手术方法之间没有发现显着差异。关于峰值垂直力（PVF），在健康犬重新检查的3个月的参考范围内，TPLO的患者明显多于MMP的犬。术后6个月，TPLO与对照组之间的平均值比较无显着差异。与对照组相比，术后6个月TPLO组分别达到93.9％（PVF）和85.9％（垂直冲动[VI]），MMP组分别达到89.4％（PVF）和79.9％（VI）的平均值。 。在主要并发症或骨关节炎的进展方面未发现明显差异。结论尽管两种手术方法之间无显着差异，但TPLO患者在临床结局方面显示出优势。
