Cranial Cruciate Ligament Rupture

Summary Objective: The optimal surgical technique for treatment of cranial cruciate ligament rupture in canine has been scientifically discussed for decades. Despite the continuous debate, proximal tibial osteotomies such as tibial plateau leveling osteotomy (TPLO) and tibial tuberosity advancement (TTA) are increasingly common. The objective of this review was to systematically evaluate the literature reporting outcome and complications associated with TPLO and TTA. Materials and methods: A systematic search of literature databases identified articles published from August 2004 to February 2016 describing evaluations of short- or longterm outcomes as well as complications following TPLO or TTA. Results: Ninety-one studies were included in this review and assigned to one out of four evidence levels. Of those, 89 studies provided the lowest evidence level and only two were assigned to the third-best evidence level. A comparison of subjective gait analyses could not detect differences in the decrease of lameness between TPLO and TTA, while objective gait analysis supports the superiority of TPLO. Fewer patients treated with TPLO were diagnosed with postoperative joint instability and TPLO had a lower percent increase of osteoarthritis (OA) after surgery. Owner satisfaction was high for both techniques. For TPLO and TTA the average total, minor, major and catastrophic complication rates were 15.9 % and 20.8 %, 7.9 % and 11.6 %, 5.2 % and 13.2 % as well as 0.8 % and 5.6 %, respectively. Conclusion and clinical significance: The assessed literature supports the hypothesis that TPLO is associated with lower complication rates, an improved clinical-functional outcome and less increase of OA compared to TTA. The results are indicative for a long-term restoration of normal limb function after TPLO. However, the strength of available evidence and the comparability of each study’s results were poor and more comparative studies are needed to draw strong conclusions towards the superiority of the TPLO over the TTA.

PICO question In dogs over 15 kg, with cranial cruciate ligament rupture is there evidence of improved outcome following tibial plateau levelling osteotomy or lateral fabellotibial suture? Clinical bottom line Although the evidence is not conclusive, the literature reviewed here suggests that tibial plateau levelling osteotomy (TPLO) results in superior limb function and owner satisfaction compared to placement of a lateral fabellotibial suture (LFS). There is currently insufficient evidence to determine if there is a difference in complication rates or osteoarthritis (OA) development following TPLO or LFS.

Cranial Cruciate Ligament Rupture

SummaryThe objective of this study was to determine whether clinical outcomes were superior and complication rates were lower in dogs that had had a cranial cruciate ligament rupture treated by tibial plateau levelling osteotomy (TPLO), compared to those dogs that had been treated using the original cranial tibial wedge osteotomy (CTWO) procedure. Thirty-seven client-owned dogs with cranial cruciate ligament rupture were included in the study: 19 dogs underwent a TPLO procedure, and 18 dogs underwent a CTWO procedure. The study was retrospective, with the data being obtained from medical records and a review of radiographs. The long-term outcome was assessed by means of an owner questionnaire using a visual analogue scale. For the majority of factors that were reviewed, there was not a significant difference in outcome between the dogs that had a TPLO or those that had undergone a CTWO. All of the dogs showed a rapid return to weight bearing after surgery, and at the six week re-examination, the majority of the dogs did not have any pain on stifle palpation. They displayed a good stifle range of motion and significantly lower lameness scores than those prior to surgery. The complication rates did not differ between the procedures, however, within this small sample of dogs, complications following a CTWO were more likely to require revision surgery.

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.

Cranial Cruciate Ligament Rupture

SummaryThe influence of the tibial tuberosity conformation on cranial cruciate ligament (CrCl) rupture was evaluated and the size of the tibial tuberosity of healthy dogs (group H) was compared with dogs with CrCl rupture (group R) and dogs treated by tibial tuberosity advancement (TTA) (group T). The medio-lateral radio-graphs of 219 stifle joints were evaluated. Relative tibial tuberosity width (rTTW), proximal tibial tuberosity angle (PTTA), tibial plateau angle (TPA), tibial width (TW) and tibial plateau length (TPL) were measured on each radiograph. Body weight (BW) was measured and relative body weight (rBW) was calculated. The data from group H was compared with that of group R and group T. Group H had significantly larger rTTW, lower BW, lower rBW and smaller PTTA than group R. A comparison of groups H and T showed that dogs from group H were significantly younger, had a lower BW, a lower rBW, a greater PTTA and a smaller rTTW. In each of the comparisons, the TPA and the TW/TPL were not significantly different. The conformation of the canine tibial tuberosity has a significant influence on CrCl rupture. We hypothesized that the smaller the tibial tuberosity width, the larger the cranial tibial thrust, which results in more rapid CrCL degeneration, thus leading to rupture in a younger population of dogs. The rTTW could be a helpful measurement for breeding selection. Only dogs with a rTTW of more than 0.90 should be used for breeding.
