BACKGROUND The current standard for treating complete tears of the anterior cruciate ligament (ACL) is reconstruction, which requires reaming a tibial tunnel. Based on recent anatomic and biomechanical studies, this reconstruction tunnel may cause injuries to the anterior meniscal root attachments. PURPOSE/HYPOTHESIS The purpose was to determine if injuries occurred to the anteromedial (AM) a...
Civil engineering structures, such as tall buildings and long span bridges, are typically designed based on the principles of material and structural mechanics. Finite element model (FEM) analysis and wind tunnel tests of scaled models are often carried out to assist structural design (see, e.g., Penman et al. 1999). However, loading conditions in the real world are always much more complicated...
Based on the comprehensive analyses of many risk factors leading to accidents in immersed tunnel engineering, it is concluded that engineering are very large and must be paid attention all aspects at stages project. This paper classifies identifies by investigating visiting relevant investigation, design construction units tunnel, then puts forward prevention control measures provide theoretica...
