Abstract Objective The aim of this study was to describe a technique for performing miniature tibial tuberosity transposition and advancement (mTTTA). The secondary objective of this study was to compare the short-term outcome and complications in small breed dogs weighing less than 12 kg undergoing surgical correction of cranial cruciate ligament disease with concurrent medial patellar luxation via either extracapsular stabilization with tibial tuberosity transposition (ECS + TTT) or mTTTA. Study Design This is a retrospective case comparison study. Results There was no significant difference in overall outcome between the ECS + TTT group and the mTTTA group when comparing 8-week postoperative radiographic healing scores as well as 2- and 8-week postoperative lameness scores. Conclusion This study concluded that the mTTTA procedure was feasible and the overall outcome and complications for the dogs that underwent ECS + TTT and those that underwent mTTTA were comparable.

SummaryObjective: To compare the resulting complications, short-term results, and client satisfaction for treatment of cranial cruciate ligament rupture using either unilateral or bilateral single-session tibial tuberosity advancement (TTA) in dogs.Methods: Medical records of 68 dogs (101 stifles) undergoing unilateral or bilateral single-session TTA were evaluated. Data gathered included signalment, history, physical examination findings, anaesthesia and surgical time, type of cranial cruciate ligament rupture and meniscal injury, implants, and intra-operative and postoperative complications. A mixed effect logistic regression analysis was performed to determine if complications were grouped by surgical procedure. Linear regression was performed to determine the influence of the variables on the occurrence of complications. Values of p <0.05 were considered significant.Results: No major intra-operative complications occurred. Twenty stifles (20%) developed a complication after surgery (11 minor, 9 major). There was no significant difference in occurrence of complications between dogs undergoing unilateral (n = 8) or bilateral single-session (n = 12) TTA (p = 0.69). The only risk factor found to be associated with complication occurrence was age.Clinical significance: This is the first report evaluating the use of bilateral simultaneous TTA. There was no significant difference in complication rates between unilateral and bilateral single-session TTA. Additional evaluation is needed to fully determine the extent of complications and long-term outcome of bilateral single-session TTA.

SummaryObjectives: This study set out to compare the outcomes of tibial tuberosity advancement (TTA) and tibial plateau levelling osteotomy (TPLO) procedures in the treatment of dogs affected with unilateral cranial cruciate ligament disease (CCLD) based on subjective parameters and objective pressure platform analysis (baropodometry).Methods: Twenty-seven adult dogs weighing over 20 kg that were presented with unilateral CCLD and were treated by the TTA (12 dogs) or TPLO (15 dogs) surgical procedure. Patient allocation to either group was based on tibial plateau angle (TPA), according to clinical guidelines (indication for TTA for dogs was a TPA up to 25°, and indication for TPLO was any TPA). Pressure platform analysis was performed prior to surgery and at four different postoperative time points (14, 30, 60 and 90 days).Results: Limb function significantly improved following TTA and TPLO, with no significant differences between groups.Conclusion: The TTA and TPLO surgical procedures were considered to be equally effective in promoting weight bearing capacity recovery in dogs affected with unilateral CCLD under the conditions of this trial.

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.

SummaryObjective: To retrospectively review and describe the incidence of complications associated with tibial tuberosity advancement (TTA) surgical procedures in a group of Boxer dogs (n = 36 stifles) and compare the data with a non-Boxer control population (n = 271 stifles).Methods: Retrospective analysis of medical records to identify all dogs that underwent TTA surgery due to cranial cruciate ligament disease. These records were categorized into two groups: Boxer dogs and non-Boxer dogs (controls – all other breeds).Results: Of the 307 stifles included, 69 complications were reported in 58 joints. The complication rate differed significantly for Boxer dogs (16/36 stifles) and non-Boxer dogs (42/271 stifles), corresponding to an odds ratio of 5.8 (confidence interval: 1.96–17.02; p-value <0.001). Boxer dogs were more likely to undergo revision surgery and to develop multiple complications. The incidence of tibial tuberosity fractures requiring surgical repair (2/36 versus 1/271) and incisional infections requiring antibiotic treatment (three in each group) was significantly higher in the Boxer group.Clinical significance: Boxer dogs had more major and multiple complications after TTA surgery than the control non-Boxer group; these complications included higher rates of revision surgery, tibial tuberosity fractures requiring stabilization, and infection related complications. The pertinence and value of breed-specific recommendations for cranial cruciate ligament disease appears to be a subject worthy of further investigation.

Cranial Cruciate Ligament Rupture

Patellar desmopathy in dogs after tibial plateau levelling osteotomy has been described in many studies. Tibial tuberosity advancement is a biomechanically different technique. It is assumed that the patellar ligament is loaded with little force similarly as after tibial plateau levelling osteotomy. Various aspects related to secondary patellar desmopathy are not completely understood. This study deals with computed radiography measurement of patellar ligament thickness after tibial tuberosity advancement in dogs with cranial cruciate ligament rupture. The thickness of the patellar ligament in exactly predetermined locations was measured from mediolateral radiographs of stifle joints. A total of 18 dogs (20 knee joints) with cranial cruciate ligament (ligamentum cruciatum craniale) rupture underwent three radiographic examinations of the knee (preoperative examination and control examination 7 and 15 weeks after the surgery). Significant difference was found between the thickness of the patellar ligament in the first and second examinations. Some of the demographic factors possibly related to patellar ligament thickness (age, sex, body weight, type of cranial cruciate ligament rupture, arthrotomy, cage size, meniscal injury, time between surgery and radiographic examination) were analyzed. However, statistical analyses did not show any effect of these factors on the thickness of the patellar ligament, except for the time between surgery and radiographic examination. These findings can extend the surgeons’ knowledge of biomechanical aspects of tibial tuberosity advancement.

The purpose of this retrospective study of 171 dogs that underwent 193 tibial tuberosity advancement (TTA) surgeries was to describe complications and owner satisfaction associated with the procedure. Complications occurred in 21 cases (11%). Subsequent meniscal tear was the most common complication (10/193, 5.2%). Increasing body weight (P=0.02–0.04) and small cage size (P=0.06) were significantly associated with postsurgical complications. Ninety-two percent of owners were satisfied with the outcome of the TTA procedure, but only 84% stated that they would be willing to have the procedure performed again. The authors concluded that TTA had a complication rate and owner satisfaction similar to other tibial osteotomies for the surgical correction of cranial cruciate ligament disease.

The objective of this study is to report on the short-term radiographic complications and bone healing associated with single-session bilateral tibial tuberosity advancements (TTAs). This retrospective study consists of 74 client-owned dogs with bilateral cranial cruciate ligament rupture that underwent consecutive single-session bilateral TTAs. Radiographs from 74 dogs (148 stifles) were evaluated for evidence of postoperative complications. One hundred forty-three of 148 stifles were scored for radiographic healing using a previously described scoring system. Variables evaluated for a relationship with radiographic complications and healing scores were: breed, age, body weight, sex, and TTA plate type. The overall radiographic complication rate was 17.6% (13/74). Twelve of the 13 radiographic complications were considered to be minor and one was major. Increasing body weight and use of a fork implant were statistically significant factors associated with an increased risk of complication. One hundred forty-three stifle radiographs met the inclusion criteria to be assessed for healing. The mean score was 2.96 out of 4.0. The overall radiographic complication rate and healing scores associated with single-session bilateral TTAs were found to be similar to those described for unilateral TTA.

ABSTRACT This study investigated the short-term radiographic healing of the osteotomy following tibial tuberosity advancement (TTA), maintenance of patellar tendon angle (PTA), and complications in dogs receiving a polyglycolic acid (PGA) TTA cage. Patients diagnosed with unilateral cranial cruciate ligament disease requiring a 9- or 12-mm TTA cage were included. Twenty-six consecutive client-owned dogs were prospectively selected for this clinical study. Age, weight, sex, breed, cage size, surgery date, and follow-up time were recorded. Radiographs were scored for healing and measured for PTA immediately, at 6 wk, and at 10 wk postoperatively. All stifles were assessed for complications throughout the study period. Stifles with PGA cages had similar overall healing scores compared to previously reported values for metallic cages, and the PTA was well maintained at 6 and 10 wk postoperatively. Polyglycolic acid cages were associated with a higher complication rate (10/26, 38%; 95% confidence interval, 0.19–0.61) compared with previously reported complication rates for metallic cages. Despite favorable healing scores and overall PTA maintenance, PGA cage use resulted in a high complication rate. Proposed advantages offered by this particular implant over currently used metallic cages are offset by this high complication rate. Additional investigation of bioabsorbable materials and implant design should be considered.
