BACKGROUND In tibial tubercle transfer (TTT) procedures, the osteotomized and transferred tibial tubercle is usually fixed into the host bone using metal screws. PURPOSE To compare the strength of fixation provided by a single bioabsorbable screw versus a metal screw for TTT. STUDY DESIGN Controlled laboratory study. METHODS Twenty-two pairs of human cadaveric tibiae were used to compare ...

In recent years, thin-walled accordion tubes under axial cyclic loading due to their appropriate energy absorption mechanism and behavioral characteristics were suggested as hysteretic metallic dampers. The effectiveness of accordion metallic damper (AMD) to protect and mitigate the response of structures under seismic loading is well established both experimentally and analytically. In this pa...

Response of soil depends on both the mechanical properties of soil itself and the nature of loading. Many geotechnical engineering problems are associated with dynamic and cyclic loadings, such as ocean wave or ice loading applied on foundations of offshore structures or bridges, dynamic loading applied on foundations of offshore wind power structures, ocean wave loading on harbor structures, s...

Background and Aim: The mismatch of the implant-abutment connection can produce instant stress and microleakage which result in mechanical and biological complications. This study aimed to investigate the influence of GapSeal® as a sealing material on the extent of microgap and microleakage at the external hexagon implant platform following cyclic loading. Materials and Methods: Sixteen implan...

BACKGROUND Successful anterior cruciate ligament reconstruction with use of soft-tissue grafts requires healing between tendon and bone. Little is known about the effect of mechanical load on the cellular and molecular cascade of tendon-to-bone healing. Understanding these mechanical influences has critical implications for postoperative rehabilitation following anterior cruciate ligament recon...

In this study, to explore the microstructure deformation mechanism of marine soft soil under cyclic loading, we analyzed dynamic properties loading via consolidation compression testing. Then, using Image-Pro Plus (IPP) 6.0 image analysis software, and according test results images from a scanning electron microscope (SEM), determined weakening effect soils different confining pressures, stress...
