Major complications associated with fork-based and screw-based tibial tuberosity advancement implants: 438 cases.

This study reports major complications in a large cohort of dogs following tibial tuberosity advancement using either a fork-based or a screw-based implant system. Four hundred thirty-eight stifles were included in the study and major complications occurred in 51 stifles. Explanatory variables evaluated included implant type and body weight. No variables evaluated were associated with major complications.

Complications majeures associées à des implants à base de fourche et de vis lors de chirurgie d'avancement de la tubérosité tibiale antérieure : 438 cas. Cette étude présente un rapport sur les complications majeures dans une grande cohorte de chiens après une chirurgie d'avancement de la tubérosité tibiale à l'aide d'un système d'implant à base de fourche ou de vis. Quatre cent trente-huit grassets ont été inclus dans l'étude et des complications majeures se sont produites dans 51 grassets. Les variables explicatives comprenaient le type d'implant et le poids corporel. Aucune variable évaluée n'a été associée à des complications majeures.(Traduit par Isabelle Vallières).

Tibial tuberosity advancement for stabilization of the canine cranial cruciate ligament-deficient stifle joint: surgical technique, early results, and complications in 101 dogs.

OBJECTIVE: To describe the surgical technique, early results and complications of tibial tuberosity advancement (TTA) for treatment for cranial cruciate ligament (CrCL)-deficient stifle joints in dogs. STUDY DESIGN: Retrospective clinical study. ANIMALS: Dogs (n=101) with CrCL-deficient stifles (114). METHODS: Medical records of 101 dogs that had TTA were reviewed. Complications were recorded and separated into either major or minor complications based on the need for additional surgery. In-hospital re-evaluation of limb function and time to radiographic healing were reviewed. Further follow-up was obtained by telephone interview of owners. RESULTS: Complications occurred in 31.5% of the dogs (12.3% major, 19.3% minor). Major complications included subsequent meniscal tear, tibial fracture, implant failure, infection, lick granuloma, incisional trauma, and medial patellar luxation; all major complications were treated with successful outcomes. All but 2 minor complications resolved. The mean time to documented radiographic healing was 11.3 weeks. Final in-hospital re-evaluation of limb function (mean, 13.5 weeks), was recorded for 93 dogs with lameness categorized as none (74.5%), mild (23.5%), moderate (2%), and severe (1%). All but 2 owners interviewed were satisfied with outcome and 83.1% reported a marked improvement or a return to pre-injury status. CONCLUSIONS: TTA is a procedure comparable with alternate methods of CrCL repair with expected good to excellent functional outcome. CLINICAL RELEVANCE: TTA procedure can be successfully used to obtain the dynamic stability of a CrCL-deficient stifle joint in dogs.
