“…In order to determine the pattern of subsequent contralateral CrCLR in affected dogs, we performed a survival analysis of three populations of dogs from different regions of the USA; data from two of these cohorts has been previously published with limited analysis on contralateral CrCL survival [2], [3]. Dogs with unilateral CrCLR that were treated surgically were studied.…”

“…It is now widely recognized that mid-substance rupture of the CrCL often occurs during normal activity, with a high incidence of bilateral rupture at the time of initial clinical presentation in the range of 11–17% [2]–[4]. The CrCL in dogs is anatomically equivalent to the anterior cruciate ligament (ACL) in human beings, and the dog is a widely used model for research into ACL biology and repair.…”

“…Analysis of this risk has usually been reported as an incidence after surgery (percentage of patients within the cohort). This risk is in the range of 22–54% at 6 to 17 months of diagnosis [2], [3], [5]–[7]. One of the limitations of this approach to data analysis is that it yields little information on the pattern of subsequent contralateral rupture.…”

BackgroundNon-contact cranial cruciate ligament rupture (CrCLR) is an important cause of lameness in client-owned dogs and typically occurs without obvious injury. There is a high incidence of bilateral rupture at presentation or subsequent contralateral rupture in affected dogs. Although stifle synovitis increases risk of contralateral CrCLR, relatively little is known about risk factors for subsequent contralateral rupture, or whether therapeutic intervention may modify this risk.Methodology/Principal FindingsWe conducted a longitudinal study examining survival of the contralateral CrCL in client-owned dogs with unilateral CrCLR in a large baseline control population (n = 380), and a group of dogs that received disease-modifying therapy with arthroscopic lavage, intra-articular hyaluronic acid and oral doxycycline (n = 16), and were followed for one year. Follow-up in treated dogs included analysis of mobility, radiographic evaluation of stifle effusion and arthritis, and quantification of biomarkers of synovial inflammation. We found that median survival of the contralateral CrCL was 947 days. Increasing tibial plateau angle decreased contralateral ligament survival, whereas increasing age at diagnosis increased survival. Contralateral ligament survival was reduced in neutered dogs. Our disease-modifying therapy did not significantly influence contralateral ligament survival. Correlative analysis of clinical and biomarker variables with development of subsequent contralateral rupture revealed few significant results. However, increased expression of T lymphocyte-associated genes in the index unstable stifle at diagnosis was significantly related to development of subsequent non-contact contralateral CrCLR.ConclusionSubsequent contralateral CrCLR is common in client-owned dogs, with a median ligament survival time of 947 days. In this naturally occurring model of non-contact cruciate ligament rupture, cranial tibial translation is preceded by development of synovial inflammation. However, treatment with arthroscopic lavage, intra-articular hyaluronic acid and oral doxycycline does not significantly influence contralateral CrCL survival.

The tibial plateau angle measurement and its applicability have been reviewed based on the literature. The measurement was made on radiographs of the stifle joint with superimposition of the femoral condyles (with maximum tolerance of 2.0-4.0mm). Due to great variation among dog populations (size, breed), mean tibial plateau angles were found to be between 16.9° and 34°, but an excessive angle was described as >35°. An appropriate measurement of the tibial plateau angle can be made at about 108 days of age. The influence on the magnitude of the measured tibial plateau angle were the limb position during radiographic examination, the measurement technique (with modifications) and the experience level of the observer. Differences in magnitudes of the tibial plateau angles in dogs with and without cranial cruciate ligament rupture were not observed. The tibial plateau angle is commonly used in osteotomy of the tibia and its magnitude in order to select the proper surgical technique. The significance of the tibial plateau angle on the aetiopathogenesis of cranial cruciate ligament disease is questionable. Other measurements of the proximal tibia were attained to determine the risk factor of cranial cruciate ligament insufficiency. Knowledge of the tibial plateau angle and factors influencing measurement errors have great clinical importance.

“…Alterações conformacionais como a luxação medial de patela (BRINKER; PIERMATEI; FLO 1990), inclinação caudal excessiva do platô tibial (READ; ROBINS, 1982) e doença articular imunomediada, como a sinovite linfocítica plasmocítica (PEDERSEN et al, 1989;DOOM et al, 2008), podem agravar o processo degenerativo e predispor a ruptura precoce do ligamento. Entre 20 e 61% dos cães que apresentam ruptura unilateral podem sofrer ruptura do ligamento contralateral (DOVERSPIKE et al, 1993;MUELLERM, 2008;GRIERSON;ASHER;GRAINGER, 2011).…”

Agradeço ao meu orientador, Professor Cassio Ricardo Auada Ferrigno, a quem devo este trabalho. Palavras não são suficientes para agradecer os últimos 6 anos que passaram. Foram 6 anos de muito trabalho, conquistas e oportunidades em minha vida; ingressar na pós-graduação da Universidade de São Paulo era um sonho muito muito distante que pôde se tornar realidade. Obrigada professor Cassio por ter me aceito como orientada, por tudo que fez por mim, pelos ensinamentos profissionais e pessoais, aprendi tudo que sei dentro da ortopedia veterinária com o senhor e espero não tê-lo decepcionado. Obrigada pela confiança e por permitir que possa ter a honra de dizer daqui para frente que fui sua orientada.Obrigada a meus pais José Mutuo Ito e Rosa Sanae Ito por todo apoio em todos os momentos e por terem feito de mim uma pessoa de caráter.Obrigada a meus irmãos Edson Massao Ito, Katiuscia Namie Ito Hiroto e seus familiares por estarem presentes na minha vida e pelo apoio nos momentos que precisei.Ao meu noivo Leonardo Seizen Yamauchi e sua família agradeço pelo amor, companheirismo e muita paciência que teve durante este período.Ao amigo César Augusto Martins Pereira pelos desenhos dos dispositivos, pela prontidão nos momentos de dificuldade e pela ajuda incondicional na realização dos ensaios biomecânicos sem a qual não teria conseguido.Aos meus queridos amigos de trabalho... dos anciãos para os mais novos: Marcos
