“…It is also known that the particularities of the contact interface can have a significant role [1], including in biomechanics analysis [2]. In this sense, it is possible to infer that the vaginal and urethral erosion rates of synthetic sub-urethral slings may be related to the mechanical properties of the filament, among other characteristics of the meshes used, such as mesh geometry.…”

The aim of this study was the comparison of the stiffness of different meshes under two types of mechanical tests. Five different mesh types were mechanically tested. The methods used consisted on uniaxial tension test (tensile stiffness) and tape ring tests, experimental continuous compression of the mesh loops (flexural stiffness). The most significant difference of tensile stiffness behaviour appears between Aris and TVTO. From the analysis of the experimental data, we divided the flexural stiffness, in two main groups. The first group includes Auto Suture and Aris meshes. The two meshes seem to have a similar flexural behaviour. The second group includes TVTO, Uretex and Avaulta. The difference between these two groups is clearly evident comparing TVTO and Aris. This study shows that there are significant differences on the mechanical properties between urogynecology meshes.

“…In another study using the PF joint, significant mechanical softening of the retropatellar cartilage was documented at 2 years in a post-trauma, treadmill exercised model, while a model without exercise did not show a reduction in cartilage stiffness (Weaver and Haut, 2005). In that study the no exercise model showed significant ossification of the impacted cartilage.…”

“…The sections were stained with Safranin-O-Fast Green and examined under light microscopy. The thickness of the subchondral plate and the overlying articular cartilage were determined by three blinded readers (DI, JW, EM) averaging across the plateau with a calibrated eyepiece, using previous protocols (Newberry et al, 1998;Weaver and Haut, 2005). The histological scoring system was based on the previous works of Colombo et al (1983) and Mazieres et al (1987) (Table 1).…”

“…The hallmark of structural changes occurring in the OA joint is cartilage loss. Although, in animal studies, it has been shown that exercise may protect against cartilage degeneration [45,46], there is limited clinical trial showing the effects of exercise on the structure of cartilage. In humans, Roos et al [47] found that moderate supervised exercise improved knee-cartilage GAG content in patients at risk of OA and they also found that improvements in pain and function were observed in parallel with the structural improvement.…”
