Objective The aim of this study was to describe short- and mid-term outcomes, complications, implant bioabsorption and owner satisfaction for a modified Maquet procedure (MMP) in which a novel bioabsorbable citrate-based implant is used as the wedge component to treat cranial cruciate ligament rupture in client-owned dogs.

Study Design Prospective clinical study of dogs (n = 13) undergoing MMP (n = 15). Intraoperative complications, postoperative complications, clinical follow-up using a 5-point lameness score and radiographs at 8 weeks and 6 months postoperatively were obtained. Mid-term outcome was assessed via physical examination, radiographs, canine orthopaedic index and owner satisfaction questionnaires.

Results No catastrophic complications occurred. Major complications occurred in 3/15 stifles. All were surgical site infections and one case required implant removal. Minor complications occurred in 9/15 stifles. Non-displaced cortical hinge fractures were the most common minor complication, and these occurred intraoperatively (4/15) or postoperatively (2/15). Three dogs achieved full function, eight dogs acceptable function and the outcome was unacceptable in two dogs. Most owners were satisfied with the procedure (11/13). Complete implant bioabsorption was not confirmed on mid-term radiographs.

Conclusion The described MMP with a citrate-based implant can produce satisfactory mid-term results. However, the long-term outcome of this procedure must be evaluated and technical modifications need to be implemented prior to larger-scale use of this implant.

目的 本研究的目的是描述改良 Maquet 手术 (MMP) 的短期和中期结果、并发症、植入物生物吸收和业主满意度，其中使用新型生物可吸收柠檬酸盐植入物作为楔形部件治疗颅骨客户拥有的狗的十字韧带断裂。

研究设计 接受 MMP ( n  = 15) 的狗 ( n = 13) 的前瞻性临床研究。获得术中并发症、术后并发症、使用 5 点跛行评分和术后 8 周和 6 个月的 X 线片的临床随访。通过体格检查、X光片、犬骨科指数和主人满意度问卷评估中期结果。

结果未 发生灾难性并发症。主要并发症发生在 3/15 膝关节。所有病例均为手术部位感染，其中 1 例需要移除植入物。9/15 窒息发生了轻微并发症。非移位皮质铰链骨折是最常见的轻微并发症，这些发生在术中 (4/15) 或术后 (2/15)。三只狗达到了全部功能，八只狗可以接受功能，两只狗的结果是不可接受的。大多数业主对程序感到满意 (11/13)。中期 X 光片未证实种植体的完全生物吸收。

结论 所描述的带有柠檬酸盐基植入物的 MMP 可以产生令人满意的中期结果。然而，在大规模使用该植入物之前，必须评估该手术的长期结果并需要实施技术修改。
