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 being...


Articulation-Induced Responses of Superficial Zone Chondrocytes in Human Knee Articular Cartilage - Effects of Shear and SlidingHsu FH, Hui AY, Chen AC, Lotz MK and Sah ROrthopeadic Research Society Annual Meeting in Las Vegas, Abstract 0256
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
Abstract

This specification covers the material requirements and characterization techniques for glass and glass-ceramic biomaterials intended for use as bulk porous or powdered surgical implants, or as coatings on surgical devices, but not including drug delivery systems. Glass and glass-ceramic biomaterials should be evaluated thoroughly for biocompatibility before human use....Read More

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

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
