A total of 696 tibial plateau leveling osteotomy (TPLO) procedures were performed over a 30-month period following TPLO training. The overall complication rate was 18.8%. Complications were classified as perioperative (1%), short-term (9.3%), and long-term (8.5%). Examples of complications encountered during the study were hemorrhage, swelling at the incision site, premature staple removal by the dog, tibial tuberosity fracture, patella tendon swelling, and implant complications. Based on the rate of complications observed, clinical outcomes of TPLO procedures within 30 months of TPLO training were considered good.

SummaryObjectives: To evaluate a tibial plateau levelling osteotomy (TPLO) saw blade positioning technique and to retrospectively evaluate the accuracy of the osteotomy position.Methods: Preoperative and postoperative radiographs of 72 cases that had a TPLO surgery using a two-wire technique were reviewed. Three measurements (A1, B1, C1) were obtained in preoperative planning using a computer template system (Orthoview Vet) which mapped the intended osteotomy position. The postoperative radiographs were analysed to determine the variability of these three measurements (A2, B2, C2) and therefore the accuracy of the osteotomy.Results: On average the least variable measurement was B2 (5%) followed by C2 (7%) and then A2 (13%). The maximum mean difference between the intended position and achieved position was 1.5 mm.Clinical significance: Despite there being a significant difference between the intended and the actual position of the osteotomy, the variation between the intended and actual tibial tuberosity width was small (5%). None of the cases suffered a tibial tuberosity fracture, which also supports the clinical value of this technique. Care must be taken to avoid inadvertent cutting of the Kirschner guide wires.

SummaryObjectives: To investigate the conformation of the proximal tibia in small breed dogs with and without cranial cruciate ligament disease (CCLD) and to identify morphologic abnormalities that may predispose to development of CCLD.Methods: Mediolateral radiographs of the entire tibia of dogs <15 kg with surgically confirmed CCLD were retrospectively evaluated. Proximal tibial width (PTW), tibial plateau length (TPL), tibial plateau angle as described by Slocum and Slocum (sTPA), proximal tibial tuberosity angle (PTTA), tibial plateau angle as described by Inauen and colleagues (nTPA), and diaphyseal tibial width (DTW) were measured. The same variables were obtained from mediolateral radiographs of the entire tibia of dogs <15 kg without CCLD. In addition, a quotient nTPA/ PTW, relative tibial tuberosity width (rTTW), and relative body weight (rBW) were calculated for each dog. Independent two-sample t-test (p = 0.05) was used to compare mean ± SD of all measured variables between the two groups.Results: Gender, age, and weight mean ± SD were not significantly different between the two groups of dogs (p <0.05). Dogs with CCLD had significantly greater sTPA (p = 0.015) and rBW (p = 0.016).Clinical significance: In dogs of small breeds, a combination of an excessively steep tibial plateau and an increased relative body weight may predispose to early CCLD development. The slope of the tibial plateau was found to be caused by an abnormal caudal angulation of the proximal tibia, a phenomenon previously associated with CCLD development in small breed dogs in individual cases.

Persistent Instability

Persistent stifle instability is a recognized complication following tibial tuberosity advancement techniques (TTAT). The aim of this study is to report the feasibility and outcome of tibial plateau leveling techniques (TPLT) to treat dogs with persistent lameness, suspected to be secondary to persistent stifle instability, following (TTAT). Medical records of dogs presented for persistent lameness after TTAT were reviewed. Preoperative data included orthopedic examination, lameness score and radiographs. Inclusion criteria included performance of a surgery to address persistent lameness and suspected instability. Short-term follow up data included orthopedic examination and radiographs of the stifle. Long-term follow up was based on postoperative Liverpool Osteoarthritis in Dogs (LOAD) questionnaire. Seven dogs were included in the study. Mean subjective preoperative lameness score was 3 ± 1.53. Mean preoperative patellar ligament angle relative to the tibial plateau (PLATP) was 94° and mean tibial plateau angle (TPA) was 28°. Six dogs had tibial plateau leveling osteotomy and one had modified cranial closing wedge ostectomy. Mean postoperative PLATP was 79° and mean TPA was 5°. Mean subjective lameness score at follow up was 0.57 ± 0.49. Minor complications were present in 2 dogs and major complication in 1 dog. Mean LOAD questionnaire score was 6.6/52. TPLT can be performed after TTAT and may improve clinical function and stability in these cases in which persistent instability is suspected.

Objectives The aim of this study was to describe a screw fixation method of the tibial tuberosity after transposition during surgical treatment of patellar luxation and to report complications and outcome of the procedure. Materials and Methods Medical records (2010–2016) of dogs treated for patellar luxation with tibial tuberosity transposition stabilization using a cortical bone screw placed adjacent to the tuberosity were retrospectively reviewed. Radiographs acquired immediately after surgery were evaluated for fissures. Proximal tibial dimensions and tibial tuberosity segments were measured. Intraoperative and postoperative complications were recorded. Results One-hundred and six dogs and 131 stifle surgeries were included. Implant complications associated with the screw occurred in 2/106 dogs (1.9%). Two dogs developed tibial tuberosity fracture and proximal displacement within 1 week of surgery and required stabilization with pin and tension band. Patellar reluxation rate following surgery was 6.9% (9/131 procedures). Presence of a fissure on postoperative radiographs increased the odds of tibial tuberosity fracture development (p < 0.001), while greater tibial tuberosity size (p = 0.023) and larger distal cortical attachment (p = 0.018) decreased the odds of fissure formation. Clinical significance Tibial tuberosity transposition can be achieved with a cortical screw placed lateral or medial to the tibial tuberosity.
