Cranial cruciate ligament rupture (CrCLR) is the most common orthopaedic cause of lameness in the hind limb in dogs. Many surgical treatments have been described, but tibial tuberosity advancement (TTA) is one of the most commonly used today. Since it was first described, TTA has evolved to reduce major complications and to arrest the progression of osteoarthrosis. The aim of this study was to assess a surgical technique called Porous TTA with flange prospectively. This study was performed in 61 dogs that underwent 65 Porous TTA with flange procedures, to validate it as an alternative CrCLR treatment. Complications and clinical outcomes (pain, lameness, weight bearing, flexion, extension, crepitation and atrophy) were reported over 3 months, i.e. at 3, 6 and 12 weeks postoperatively.
The results showed a positive clinical outcome, a minor complication rate of 47.69% at the first review 3 weeks postoperatively, 10.77% at the second one (6 weeks after the surgery) and 4% at the third one (at 12 weeks). Major complications were observed only at the last review, with one case that had an infection requiring implant removal; this represented 1.5% of cases. Variables evaluated for a relationship with complication scores and improvement were body condition score, sex, age, breed, body weight, breed size, side of the affected limb, traumatic anamnesis and time of lameness before surgery. No relationship was detected.
Clinical outcomes and complications show that Porous TTA with flange is an efficient alternative for surgical treatment of CrCLR in dogs.
犬后肢十字韧带断裂（CrCLR）是最常见的骨科跛行原因。已经描述了许多手术治疗方法，但胫骨结节前移术（TTA）是目前最常用的方法之一。自首次描述以来，TTA 已经发展到可以减少主要并发症并阻止骨关节炎的进展。本研究的目的是前瞻性评估一种称为带翼多孔 TTA 的手术技术。本研究对 61 只接受 65 例带翼多孔 TTA 手术的犬进行了研究，以验证其作为 CrCLR 治疗的替代方法。在 3 个月内（即术后 3、6 和 12 周）报告了并发症和临床结果（疼痛、跛行、负重、弯曲、伸展、弹响和萎缩）。
结果显示出积极的临床结果，术后 3 周第一次复查时的轻微并发症发生率为 47.69%，术后 6 周第二次复查时为 10.77%，术后 12 周第三次复查时为 4%。仅在最后一次复查时观察到主要并发症，一例感染需要取出植入物；这占病例的 1.5%。评估与并发症评分和改善相关的变量包括身体状况评分、性别、年龄、品种、体重、品种大小、患肢侧、创伤史和术前跛行时间。未发现相关性。
临床结果和并发症表明，带翼多孔 TTA 是犬 CrCLR 手术治疗的有效替代方法。
