摩擦
摩擦测试确定两个表面在受到接触力时相互滑动的难易程度。在这些测试中通常观察到两种主要现象：静摩擦和动摩擦。静摩擦力是阻止物体从静止状态移动的力，而动摩擦力是在两个表面已经运动时作用于它们之间的力。BMM 开发的软件使用垂直平台施加法向力，而其他平台施加旋转或平移运动，您可以轻松确定测试中涉及的摩擦系数和力。摩擦测试的目的涵盖了广泛的兴趣领域。例如，测试一种新型润滑剂的有效性或比较两个样品的表面te性。

Introduction: During daily physical activities, joint articulation results in 3-10% compression in its overall thickness. There is also consensus that articulation is a combined process of shearing and sliding, with relative rotational and translational motions between femoral condyle and tibia cartilage at least at the millimeter scale 2,3. The macroscale motions in the joint which translates...Read More Development of a Sequence of Mechanical Tests for Articular Cartilage at a Single LocationSim S, Chartrand A, Lavallee AP, Tessier J, Garon M, Quenneville E and Buschmann MDOrthopeadic Research Society Annual Meeting in Orlando, 2016
In a recent study, our group has highlighted the importance of considering the natural topographic variability of the mechanical properties over the articular surface, particularly in the context of cartilage repair, where it can screen the effect of a treatment [1]. Moreover, the availability of test sample is limited in those repair studies since the regions of interest are often limited in size....Read More
ASTM D1894 - Standard Test Method for Static and Kinetic Coefficients of Friction of Plastic Film and SheetingASTM International, West Conshohocken, PA, 2014, www.astm.org
Significance and Use
4.1 Measurements of frictional properties may be made on a film or sheeting specimen when sliding over itself or over another substance. The coefficients of friction are related to the slip properties of plastic films that are of wide interest in packaging applications. These methods yield empirical data for control purposes in film production. Correlation...Read More
ASTM F1538 - Standard Specification for Glass and Glass Ceramic Biomaterials for ImplantationASTM International, West Conshohocken, PA, 2009, www.astm.org

Tailoring hydrogel surface properties to modulate cellular response to shear loadingMeinert C, Schrobback K, Levett PA, Lutton C, Sah R and Klein TJActa biomaterialia, October 2016. DOI: 10.1016/j.actbio.2016.10.011
Biological tissues at articulating surfaces, such as articular cartilage, typically have remarkable low-friction properties that limit tissue shear during movement. However, these frictional properties change with trauma, aging, and disease, resulting in an altered mechanical state within the tissues. Yet, it remains unclear how these surface changes affect the behaviour of embedded cells when the...Read More
Mechanical characterization of matrix-induced autologous chondrocyte implantation (MACI®) grafts in an equine model at 53 weeksGriffin DJ, Bonnevie ED, Lachowsky DJ, Hart JC, Sparks HD, Moran N and Bonassar LJJournal of biomechanics, 48(10), 1944-1949. (2015)
There has been much interest in using autologous chondrocytes in combination with scaffold materials to aid in cartilage repair. In the present study, a total of 27 animals were used to compare the performance of matrix-assisted chondrocyte implantation (MACIs) using a collagen sponge as a chondrocyte delivery vehicle, the sponge membrane alone, and empty controls. A total of three distinct types of...Read More
Effect of synovial fluid on boundary lubrication of articular cartilageSchmidt TA and Sah RLOsteoarthritis Cartilage. 2007 Jan;15(1):35-47. Epub 2006 Jul 21
OBJECTIVES: The lubrication of articulating cartilage surfaces in joints occurs through several distinct modes. In the boundary mode of lubrication, load is supported by surface-to-surface contact, a feature that makes this mode particularly important for maintenance of the normally pristine articular surface. A boundary mode of lubrication is indicated by a kinetic friction coefficient...Read More
Combined Mechanical Characterizations Increases Sensitivity in the Assessment of Human Cartilage DegenerationSim S, Hadjab I, Chevrolat L-A, Masse M, Tong AL, Lavigne P, Garon M, Quenneville E and Buschmann MDAccepted for a podium presentation at ORS 2017
Introduction: We published a recent study showing superior sensitivity of electromechanical and indentation (instantaneous response) assessments versus well-established techniques, including histological Mankin score, to characterize cartilage degeneration. This study aims to determine whether the combination of instantaneous, relaxation and equilibrium mechanical properties and friction...Read More
Evaluation of genipin for stabilization of decellularized porcine cartilageElder S, Pinheiro A, Young C, Smith P and Wright EJ Orthop Res. 2016 Nov 18. doi: 10.1002/jor.23483
Abstract
We speculate that an acellular osteochondral xenograft may be a good alternative to allografts for repair of focal articular cartilage lesions. In order to make a xenograft resistant to enzymatic degradation and to prevent a chronic immune response it may beneficial to stabilize it through crosslinking. The concept is analogous to treatment of porcine bioprosthetic heart...Read More
Biomechanics and MechanoBiology of Human Cartilage ArticulationHsu FH, Alonso E, Raleigh AR, Saleh AA, Masuda K, Lotz MK, Chen AC and Sah ROrthopeadic Research Society Annual Meeting, 2016, Orlando, USA, Poster abstract 1428
Introduction: During joint articulation, cartilage, particularly that near the articular surface, undergoes a complex combination of compression, shear, and sliding.1,2 In vitro analyses have focused on cartilage biomechanics in response to relative surface movement at a constant velocity after startup. However, joint movement typically involves variability in the relative surface velocity....Read More
Composite hydrogel: A high fidelity soft tissue mimic for surgeryTan, Z., Dini, D., Rodriguez y Baena, F., & Forte, A. E.Materials & Design, 160, 886894. https://doi.org/10.1016/j.matdes.2018.10.018
Accurate tissue phantoms are difficult to design due to the complex non-linear viscoelastic properties of real soft tissues. A composite hydrogel, resulting from a mix of poly(vinyl) alcohol and phytagel, is able to reproduce the viscoelastic responses of different soft tissues due to its compositional tunability. The aim of this work is to demonstrate the flexibility of the composite hydrogel...Read More
The role of synovial fluid constituents in the lubrication of collagen-glycosaminoglycan scaffolds for cartilage repairAustyn R. Matheson, Eamon J. Sheehy, Gregory D. Jay, W. Michael Scott, Fergal J. O'Brien, Tannin A. SchmidtJournal of the Mechanical Behavior of Biomedical Materials, 2021, 104445, ISSN 1751-6161, https://doi.org/10.1016/j.jmbbm.2021.104445
Abstract
Extracellular matrix (ECM)-derived scaffolds have shown promise as tissue-engineered grafts for promoting cartilage repair. However, there has been a lack of focus on fine-tuning the frictional properties of scaffolds for cartilage tissue engineering as well as understanding their interactions with synovial fluid constituents. Proteoglycan-4 (PRG4) and hyaluronan...Read More
