Effects of freezing on the mechanical properties of articular cartilage.
Preventing cartilage injury is important in minimizing the long term debilitating effects of osteoarthritis. Accurate subfracture injury prediction must take into account the possible effects that freeze thaw cycles may have on the mechanical properties of cartilage tissue. This paper addresses this concern with matched pair testing of various low temperature storage techniques against fresh co...
متن کاملLocation dependent properties of cartilage measured by ultrasound and indentation: Two case studies of ovine and minipig knee articular cartilage
INTRODUCTION: The topographic analysis of cartilage mechanical properties has been of particular interest since it is known that physiological loading patterns differ with location in a synovial joint. Site-specific in vivo material characterization of articular cartilage has previously been performed using both ultrasound and indentation techniques [1-3]. Ultrasound biomicroscopy (UBM) uses hi...
متن کاملNonlinear optical microscopy of articular cartilage.
OBJECTIVE To assess the ability of nonlinear optical microscopy (NLOM) to image ex vivo healthy and degenerative bovine articular cartilage. METHOD Fresh bovine femoral-tibial joints were obtained from an abattoir. Articular cartilage specimens were harvested from the tibial plateau. Normal and degenerative specimens were imaged by NLOM and subsequently fixed and processed for histological ex...

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولValidation of Articular Cartilage Tensile Moduli from Transversely Isotropic Biphasic Indentation Fem Analysis
Indentation testing has frequently been used as a method to obtain the material properties of articular cartilage in compression [1]. To account for the wellestablished anisotropic nature of cartilage [2] previous studies have modeled the cartilage as a transversely isotropic biphasic material using optimized FEM curvefitting techniques to obtain the material properties of the tissue in compres...
