“…13,15 Despite the grossly normal appearance of menisci at this stage, these matrix changes initiate a cascade that subsequently leads to meniscal degeneration, gross fissuring and ultimately, complete maceration. 12 Results of an experimental study 14 in dogs indicated that the medial meniscus was grossly disrupted in 86% of cranial cruciate ligament-deficient stifle joints within 6 months.…”

“…[8][9][10][11] Secondary meniscal injuries occur weeks to months after rupture of the cranial cruciate ligament and are a consequence of craniocaudal subluxation of the femorotibial joint. [12][13][14][15] Meniscal injury may also be a complication that develops late after surgical reconstruction of the ruptured cranial cruciate ligament. 16 Most injuries of the medial meniscus involve the caudal pole, which may be torn from its capsular attachment and folded forward under the medial femoral condyle.…”

Centro instantâneo de movimento, na avaliação ex-vivo da reconstrução extra-articular fabelo-tibial, após transecção do ligamento cruzado cranial em cães

Este estudo comparou o efeito na biomecânica articular de dois fios de sutura, aço e polipropileno, na estabilização do joelho após transecção do ligamento cruzado cranial de cães, utilizando-se a técnica extra-articular de sutura fabelo-tibial. O centro instantâneo de movimento e o vetor velocidade resultante, foram calculados por meio de análise radiográfica das articulações fêmur-tíbio-patelares de doze cães, antes e após a desestabilização e estabilização articular. Todas as articulações apresentavam centro instantâneo e vetor velocidade normais antes da transecção do ligamento. Após a mesma, observou-se o posicionamento anormal do vetor velocidade em onze articulações. Na análise radiográfica posterior à estabilização articular, quatro articulações do grupo nos quais foi empregado o fio de aço continuaram apresentando posicionamento anormal do vetor velocidade, enquanto todas as articulações do grupo em que foi utilizado o fio de polipropileno apresentaram vetor velocidade em posição tangente às superfícies ósseas. Conclui-se que o fio de polipropileno é mais indicado na estabilização extra-articular por manter a biomecânica articular inalterada.

“…With the evidence of meniscectomy causing the progression of osteoarthritis (OA), treatment of meniscal tears is towards to maximal preservation of meniscal tissue. Since damaged portions of the meniscus should be removed to avoid the progression of OA, maximal retention of grossly normal menisci is desirable [3]. However, it is difficult to ensure that the grossly normal portions are without any pathologic changes.…”

The potential of optical coherence tomography in meniscal tear characterization

et al. 2009

Meniscal tear is one of the most common knee injuries leading to pain and discomfort. Partial and total meniscectomies have been widely used to treat the avascular meniscal injuries in which tears do not heal spontaneously. However, the meniscectomies would cause an alteration of the tibiofemoral contact mechanics resulting in progressive osteoarthritis (OA). To mitigate the progression of OA, maximal preservation of meniscal tissue is recommended. The clinical challenge is deciding which meniscal tears are amenable to repair and which part of damaged tissues should be removed. Current diagnosis techniques such as arthroscopy and magnetic resonance imaging can provide macrostructural information of menisci, but the microstructural changes that occur prior to the observable meniscal tears cannot be identified by these techniques. Serving as a nondestructive optical biopsy, optical coherence tomography (OCT), a newly developed imaging modality, can provide high resolution, cross-sectional images of tissues and has been shown its capabilty in arthroscopic evaulation of articular cartilage. Our research was to demonstrate the potential of using OCT for nondestructive characterization of the histopathology of different types of meniscal tears from clinical cases in dogs, providing a fundamental understanding of the failure mechanism of meniscal tears. First, cross-sectional images of torn canine menisci obtained from the OCT and scanning electronic microscopy (SEM) were be compared. By studying the organization of collegan fibrils in torn menisci from the SEM images, the feasibility of using OCT to characterize the organization of collegan fibrils was elucidated. Moreover, the crack size of meniscal tears was quantatitively measured from the OCT images. Changes in the crack size of the tear may be useful for understanding the failure mechanism of meniscal tears.

Pathologic changes in grossly normal menisci in dogs with rupture of the cranial cruciate ligament

Abstract: Histologic changes in meniscal cartilage correlate with gross appearance of the cartilage at time of surgery for rupture of the CCL. On the basis of minimal histologic changes, routine removal of grossly normal menisci does not appear to be warranted.
