Abstract Background Cranial cruciate ligament (CCL) rupture is one of the most common causes of limb lameness in dogs. Surgical techniques based on tibial osteotomies such as tibial plateau leveling osteotomy and tibial tuberosity advancement are used to eliminate dynamic thrust. Tibial tuberosity advancement (TTA) uses an osteotomy fixated by cage, plates, forks and screws to change the relationship of the patellar tendon and tibial plateau angle. Tension band wiring technique is one of the most common surgical methods used to treat a tension fracture and remains the gold standard for the treatment of tibial tuberosity fractures. In this study, we compared experimentally the biomechanical effect of application of tension band wiring compared to other techniques for the fixation of the TTA osteotomy. The techniques compared to are standard commercially available systems for TTA fixation. Results Tension band wiring (TBW) presented the higher resistance to failure compared to all the other surgical procedures, with the highest values found in the TBW group with 1.47 ± 0.07 N and the lowest in the TTA cage (0.82 ± 0.08) and TTA-2 (0.85 ± 0.06) groups with statistically significant differences in all cases (P < 0.001). TTA rapid and TTA plate groups exhibited a similar strength, and same happened between TTA-2 and TTA cage groups. All the other comparisons by pair were significantly different with P < 0.001. Conclusions Results suggest that fixating the osteotomy with tension band wiring increases the strength of the fixation and decrease the risk of implant failure. Further clinical studies are needed to demonstrate in vivo reliability and to test different variables such as size and weight of dogs. These results could have important clinical implications in the treatment of CCL ruptures.

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.

Abstract Objective The aim of this study was to compare outcomes after tibial plateau levelling osteotomy (TPLO) and modified Maquet procedure (MMP) for the treatment of cranial cruciate ligament rupture (CCLR) in dogs using clinical and radiographic evaluation and treadmill-based force plate gait analysis. Study Design This study was a prospective, randomized, controlled study. Materials and Methods Sixty-one dogs (76 joints) with CCLR were treated with TPLO (n = 30 dogs, 41 joints) or MMP (n = 31 dogs, 35 joints) and compared with a control group of 16 healthy Labrador Retrievers. Outcomes after surgery were compared by clinical orthopaedic assessment, radiographic evaluation and force plate gait analysis performed preoperatively, and then at 6 weeks, 3 and 6 months postoperatively. For objective comparison of ground reaction forces, the data were compared with the control group. Major complications were reported. Results A significant improvement in ground reaction forces was reached in all surgically treated dogs. No significant difference was found between the surgical methods at any postoperative re-examination. With regard to peak vertical force (PVF), there were significantly more patients with TPLO within the reference range of healthy dogs at the 3 months re-examination than dogs with MMP. There was no significant difference in mean value comparisons between TPLO and control groups 6 months postoperatively. Compared with the control group, mean values of 93.9% (PVF) and 85.9% (vertical impulse [VI]) were reached by the TPLO group and 89.4% (PVF) and 79.9% (VI) by the MMP group, 6 months postoperatively.No significant differences were found regarding major complications or progression of osteoarthritis. Conclusions Although no significant differences were found between the surgical methods, TPLO patients showed superiority with regard to clinical outcome.

SummaryObjectives: To evaluate the degree of lateralization achievable and strength of tibial tuberosity transposition and advancement (TTTA) relative to pin and tension band wiring (PTBW) for lateral tibial tuberosity transposition.Methods: Six pairs of cadaveric tibiae were used. Tibial tuberosity position was determined with computed tomography (CT); bones were then randomly assigned into TTTA and PTBW groups. The PTBW group had a tibial tuberosity osteotomy and fixation with pin and tension band wiring. The TTTA group had a tibial tuberosity advancement performed with lateralization of the tibial tuberosity by 50% of cage depth, using spacers on the cranial cage screw. Postoperative CT images showed lateralization and craniocaudal deviation. Single axial distractive loading was applied to the patella at 90° to the tibial plateau, and peak load, energy, and stiffness were calculated.Results: There were significant differences in lateralization (PTBW: 67.92 ± 5.1 %; TTTA: 88.51 ± 5.5 %) (p = 0.0173) and craniocaudal deviation (PTBW: –8.30 ± 1.4 %; TTTA: 6.83 ± 0.6) (p = 0.0001). There were no significant differences in peak load to failure (N) (PTBW: 1448 ± 121; TTTA: 1597 ± 43) (p = 0.4541), energy to failure (N/mm) (PTBW: 15013 ± 2719; TTTA: 17314 ± 887) (p = 0.646), or stiffness (N/mm)(PTBW: 102.8 ± 4.7; TTTA: 92.9 ± 4.8) (p = 0.2716).Clinical significance: The TTTA was more effective at lateralization of the tibial tuberosity, and of comparable strength to PTBW. Greater support of the osteotomized fragment with TTTA may resist cyclic loading, and requires evaluation.

Summary Objectives: To calculate the difference between the desired tibial tuberosity advancement (TTA) along the tibial plateau axis and the advancement truly achieved in that direction when cage size has been determined using the method of Montavon and colleagues. To measure the effect of this difference on the final patellar tendon-tibial plateau angle (PTA) in relation to the ideal 90°. Methods: Trigonometry was used to calculate the theoretical actual advancement of the tibial tuberosity in a direction parallel to the tibial plateau that would be achieved by the placement of a cage at the level of the tibial tuberosity in the osteotomy plane of the tibial crest. The same principle was used to calculate the size of the cage that would have been required to achieve the desired advancement. The effect of the difference between the desired advancement and the actual advancement achieved on the final PTA was calculated. Results: For a given desired advancement, the greater the tibial plateau angle (TPA), the greater the difference between the desired advancement and the actual advancement achieved. The maximum discrepancy calculated was 5.8 mm for a 12 mm advancement in a case of extreme TPA (59°). When the TPA was less than 31°, the PTA was in the range of 90° to 95°. Clinical significance: A discrepancy does exist between the desired tibial tuberosity advancement and the actual advancement in a direction parallel to the TPA, when the tibial tuberosity is not translated proximally. Although this has an influence on the final PTA, further studies are warranted to evaluate whether this is clinically significant.

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.

Summary Objectives: To compare tibial plateau angle (TPA) among Labrador Retrievers, Rottweilers, Boxers, and German Shepherd Dogs that had undergone tibial plateau leveling osteotomies (TPLO) for cranial cruciate ligament disease, and to determine if higher TPAs are associated with increased risk for concurrent meniscal injury. Methods: This was a retrospective study including 275 client-owned dogs of one of the four aforementioned breeds that received TPLO radiographs between 1999 and 2005 prior to undergoing the TPLO procedure. The TPA measured by the original surgeon was compared among four breeds and analyzed with respect to presence or absence of meniscal injury diagnosed via arthroscopy or arthrotomy at the time of surgery. Results: Labrador Retrievers, Rottweilers, Boxers, and German Shepherd Dogs had mean TPAs of 25.9°, 26.2°, 25.9°, and 28.2°, respectively. The TPA of German Shepherd Dogs was significantly higher than that of the other breeds of dogs examined. TPA higher than the mean for dogs in this study did not significantly increase the risk for concurrent meniscal injury. Clinical significance: German Shepherd Dogs with cranial cruciate ligament disease had a significantly higher TPA compared to the other breeds examined. Higher TPA did not increase the likelihood of meniscal tears in this study. However, several variables that were not assessed, including the degree of cranial cruciate ligament integrity at the time of surgery and the time between original CrCL deficiency and surgical assessment, could have affected this analysis.
