Paradoxical anterior movement of the femoral condyles after total knee arthroplasty (TKA) often attenuates the extension mechanism and causes a suboptimal outcome. The medial-pivot implant design aimed to confine anterior movement and emulate physiologic knee kinematics. In our study, a consecutive series of 58 medial-pivot TKA were enrolled with a minimum(More)
Metaphyseal fractures of the distal tibia near the ankle joint are difficult to manage. Poor soft tissue coverage and comminution of the fracture complicate open reduction. This prospective study aims to evaluate the practicability of using interlocking nails to treat such fractures. Using the method of closed reduction and internal fixation with a(More)
Variable degrees of bony deficiencies often complicate revisional arthrolasties of acetabular components and represent challenges to orthopedic surgeons. Many solutions exist and cementless jumbo cup reconstruction had been proven to be a feasible and successful method. Our study aimed to access the results of these cementless giant cups for managing(More)
Spinal epidural lipomatosis is a rare disorder characterized by the pathological overgrowth of epidural fat and often causes extradural compression which may mimic other spinal disorders. Steroid administration is a well-documented etiology. We report a case of spinal epidural lipomastosis without history of steroid administration. The initial manifestation(More)
The function of type II collagen in cartilage is well documented and its importance for long bone development has been implicated. However, the involvement of type II collagen in bone marrow derived mesenchymal stem cell (BMSC) osteogenesis has not been well investigated. This study elucidated the pivotal role of type II collagen in BMSC osteogenesis and(More)
Novice learners demonstrate marked difficulty in using reading-study systems to read academic textbooks. One notable problem is that the process and constructed knowledge is complex. Novice learners are required to exert considerable effort in applying the process and in remembering the knowledge, resulting in lower motivation and fewer cognitive resources(More)

—Annotation is a frequently used learning skill. When taking note, the reader only focuses on partial content of a topic or a segment. The note would be non-organized and piecemeal. Therefore, the relationship between topic and annotation would be lost or indirect including the relationship among annotations. Thus, because of the dispersion of annotations,(More)
Numerous studies have proved that graphic strategies, such as graphic organization and concept mapping, can facilitate improving reading comprehension. However, the question as to what graphic strategies can improve argumentative essay reading comprehension ability is not yet resolved. To determine whether graphic strategies can improve students’ reading(More)
