“…The use of different pressure sensors for in vitro tibiofemoral contact analyses has been previously reported for canine, 18 porcine, 28 sheep, 14,29 and human knee joints. 11,12 To place the pressure sensors under the menisci, the meniscotibial coronary ligaments had to be dissected, but this has no impact on the contact mechanics under axial compression.…”

“…In our study no additional tool was used to secure the sensor, because no macroscopic sensor movement was observed during the loading cycles. DVRTs are frequently used in vitro to determine meniscal hoop strain in canine 18 and human knee joints. 16,22 However, limitations were reported due to the restricted local measurement 22 of the DVRTs and their sensitivity to interference from surrounding tissue.…”

“…However, contact mechanics of the uninvolved compartment is affected after total meniscectomy. 15,17,18 We hypothesize that a partial meniscectomy, as it is performed after radial tears in the posterior medial horn, affects both the medial and lateral compartments. In such cases, performing a wedge osteotomy could worsen the uninvolved compartment.…”

ABSTRACT:We examined the influence of partial meniscectomy of 10 mm width on 10 human cadaveric knee joints, as it is performed during the treatment of radial tears in the posterior horn of the medial meniscus, on maximum contact pressure, contact area (CA), and meniscal hoop strain in the lateral and medial knee compartments. In case of 08 and 308 flexion angle, 20% and 50% partial meniscectomy did not influence maximum contact pressure and area. Only in case of 608 knee flexion, 50% partial resection increased medial maximum contact pressure and decreased the medial CA statistically significant. However, 100% partial resection increased maximum contact pressure and decreased CA significantly in the meniscectomized medial knee compartment in all tested knee positions. No significant differences were noted for meniscal hoop strain. From a biomechanical point of view, our in vitro study suggests that the medial joint compartment is not in danger of accelerated cartilage degeneration up to a resection limit of 20% meniscal depth and 10 mm width. Contact mechanics are likely to be more sensitive to partial meniscectomy at higher flexion angles, which has to be further investigated. ß

“…O proprietário pode ouvir ruído com som semelhante a "clic" ou crepitação quando o paciente salta ou anda, e este som pode ser audível durante as manobras de flexão e extensão no exame físico 1 . A ruptura é mais frequente em cães de raças grandes e gigantes; nas pequenas, a lesão é menos comum, possivelmente porque depois da ruptura do ligamento cruzado o membro locomotor é mantido elevado e em flexão, diminuindo as cargas sobre os meniscos 2,7,8,9 . A maioria das rupturas de menisco é medial, envolvendo o corno caudal 1,2,3,6 .…”

“…Bennett e O tratamento instituído para a ruptura parcial de menisco foi a meniscectomia parcial e para a ruptura total a meniscectomia total, corroborando o tratamento utilizado por Bennet e May 10 . A meniscectomia total deve ser evitada com a finalidade de um melhor prognóstico para o animal e para a funcionabilidade do joelho 8 .…”

ResumoO trabalho descreve as lesões de menisco associadas com ruptura do ligamento cruzado cranial em 82 pacientes de diferentes raças, idades e pesos, com o objetivo de avaliar o tipo de ruptura de menisco associada a lesões do ligamento cruzado cranial. No período pré-operatório, os animais foram submetidos à avaliação clínica e radiológica. Todos os animais apresentaram ruptura total ou parcial do ligamento cruzado cranial; 21 (24,14%) animais não apresentaram nenhuma lesão de menisco, os restantes (75,86%) apresentaram apenas lesão no menisco medial. As lesões encontradas no menisco medial foram as seguintes: 33 joelhos (37,93%) apresentaram eversão do corno caudal (Tipo 1); 15 (17,24%) apresentaram lesão em alça de balde (Tipo 6); 3 (3,45%) lesão de fibrilação (Tipo 4); 3 (3,45%) ruptura longitudinal múltipla (Tipo 3); 3 (3,45%) lesão longitudinal (Tipo 2); 1 (1,15%) lesão tipo 7; e 10 (11,49) apresentaram lesões múltiplas. A meniscectomia parcial do menisco medial foi realizada em 63 (72,41%) joelhos e a meniscectomia total em 3 (13,04%). O procedimento cirúrgico para a resolução da ruptura do ligamento cruzado cranial incluiu: avanço da tuberosidade tibial (TTA) (49 joelhos), osteotomia niveladora do platô tibial (TPLO) (15 joelhos), osteotomia em cunha da tíbia (CWO) (14 joelhos), extracapsular (quatro joelhos) e meniscectomia (cinco joelhos). Todos os casos evoluíram com o retorno à função habitual do membro pélvico acometido na primeira semana do período pós-operatório, e com a ausência de complicações. A alta porcentagem (75,86%) de ruptura do menisco medial encontrada no presente trabalho demonstra a importância da avaliação prévia dos meniscos antes da realização da técnica de estabilização da articulação femorotibiopatelar.

AbstractThe following study describes meniscus ruptures associated to cranial cruciate ruptures, in 34 dogs of different breeds, ages and weights. Before surgery the animals underwent clinical and radiographic examinations. All animals presented either total or partial cranial cruciate ruptures: 21 (24.14%) of the animals didn't present any meniscus lesions, and the rest (75.86%) presented only a medial meniscus lesion. The lesions found in the medial meniscus were the following: 33 stifles (37.93%) presented with eversion of the caudal pole (Type 1), 15 (17.24%) showed a bucked handle lesion (Type 6), 3 (3.45%) presented with fibrillation lesion (Type 4), 3 (3.45%) multiple fibrillation lesion (Type 3), 3 (3.45%) longitudinal lesion (Type 2), 1 (1.15%) lesion type 7 and 10 (11.49%) presented multiple lesion. Surgical procedure for cranial cruciate rupture included: tibial tuberosity advancement (TTA) (49 stifle), tibial plateau leveling osteotomies (TPLO) (15 stifle), closing wedge osteotomy (CWO) (14 stifle), extracapsular (4 stifle) and meniscectomy alone (5 stifle), and all these techniques guaranteed weight baring and return to function in the first week after surgery, with no complications. Through this study we co...
