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.

Evaluation of the triple tibial osteotomy. A new technique for the management of the canine cruciate-deficient stifle.

The triple tibial osteotomy (TTO) is a technique which combines the features of tibial tuberosity advancement and wedge osteotomy for the treatment of complete and partial cruciate ligament injuries in dogs. In this paper, the technique is described and the results of a prospective study of 64 consecutive cases are presented. TTO provided a satisfactory clinical outcome in a very high percentag...
