Characterisation of native and decellularised porcine tendon under tension and compression: A closer look at glycosaminoglycan contribution to tendon mechanics

2022, Journal of BiomechanicsCitation Excerpt :Specifically, impinged regions of tendon possess fibrocartilage-like structural and compositional features that are lost when impingement is removed and are absent in non-impinged areas (Malaviya et al., 2000; Gillard et al., 1979; Maffulli et al., 2006). In some cases, this tendon fibrocartilage may be a protective adaptation that helps tendons withstand compressive forces from bone (Docking et al., 2013; Wren et al., 2000; Vogel and Koob, 1989; Koob et al., 1992). However, excessive impingement has also been implicated as a causative factor in several tendinopathies, thus motivating interest in understanding the link between impingement and altered tendon phenotype (Cook and Purdam, 2012; Almekinders et al., 2003; Giori et al., 1993).
Effects of electromechanical reshaping on mechanical behavior of exvivo bovine tendon
2020, Clinical BiomechanicsCitation Excerpt :Their coupling of high fixed charge density and charge-to-charge repulsion forces also provide resistance to high compressive loads (Berenson et al., 1996). Evidence that compressive loading of tendons regulates proteoglycan synthesis further emphasizes the importance of proteoglycans for tendon compressive integrity (Koob et al., 1992). The interaction of water molecules, free cations, and macromolecules with a fixed negative charge density such as collagen and proteoglycans play an essential role in tendon biomechanical properties.

2015, Journal of BiomechanicsCitation Excerpt :This indicates that the compressive response of tendon tissue is physiologically relevant and suggests that PGs are potentially involved in the load bearing mechanisms. Only few compression experiments on tendons have been reported (Koob et al., 1992; Lee et al., 2000; Williams et al., 2008; Fang et al., 2014) in contrast to tensile testing, which has been applied on various length scales, reaching from single collagen molecules (Sun et al., 2002, 2004; Bozec and Horton, 2005) and fibrils (Graham et al., 2004; Shen et al., 2008; Svensson et al., 2010, 2012) over fascicles (Screen et al., 2004, 2013; Clemmer et al., 2010; Thorpe et al., 2012) to whole tendons and tendon segments (Wren et al., 2003; Lake et al., 2010; Rigozzi et al., 2009; Kahn et al., 2010, 2013). Many of the aforementioned studies were used to identify the material parameters of constitutive models establishing relations between tissue stress and strain.
