Articular cartilage defects in the knee of young or active individuals remain a problem in orthopaedic practice. These defects have limited ability to heal and may progress to osteoarthritis. The prevalence of knee osteoarthritis among athletes is higher than in the non-athletic population. The clinical symptoms of osteoarthritis are joint pain, limitation(More)
In anatomic double-bundle anterior cruciate ligament (ACL) reconstruction, it is more technically demanding, even for experienced surgeons, to place 2 femoral tunnels within the ACL attachment than to place 2 tibial tunnels. We describe a technique using a three-dimensional (3-D) fluoroscopy-based navigation system to place 2 femoral tunnels accurately.(More)
In this paper, we propose a novel web content summarization method that creates a text summary by exploiting user feedback (comments, annotations etc.) in the social bookmarking service. We first analyze the feasibility to utilize user feedback in the summarization, and then demonstrate how the social summary which best represents the topics of the web(More)
The purpose of this study was to know which tunnel—the anteromedial (AM) bundle or the posterolateral (PL) bundle—should be prepared first to create the 2 femoral tunnels accurately in anatomic double-bundle (DB) anterior cruciate ligament (ACL) reconstruction. Thirty-four patients were divided into 2 groups of 17 depending on the sequence of preparation of(More)
From October 2003 to September 2004, we collected the specimen from 399 patients with lower respiratory tract infections in 12 institutions in Japan, and investigated the susceptibilities of isolated bacteria to various antibacterial agents and patients' characteristics. Of 474 strains that were isolated from specimen (mainly from sputum) and assumed to be(More)
Revision anterior cruciate ligament (ACL) reconstruction is accompanied by several technical challenges that must be addressed, such as a primary malpositioned bone tunnel, pre-existing hardware, or bone defects due to tunnel expansion. We describe a surgical technique used to create an anatomic femoral socket using a 3-dimensional (3D) fluoroscopy-based(More)
A single-chip MPEG-2 MP@ML codec, integrating 3.8M gates on a 72-mm die, is described. The codec employs a heterogeneous multiprocessor architecture in which six microprocessors with the same instruction set but different customization execute specific tasks such as video and audio concurrently. The microprocessor, developed for digital media processing,(More)
The purpose of this study was to evaluate the clinical results of anatomic double-bundle (DB) anterior cruciate ligament (ACL) reconstruction in which anatomic position of femoral socket apertures was validated using three-dimensional (3D) computed tomography (CT) modelling. Anatomic DB ACL reconstructions with hamstring autografts were performed in 34(More)
Interconnect delay is dominant in today’s high speed VLSI circuits and there have been various works to resolve it [1],[2],[3]. A repeater insertion tool “RePertory” has been newly developed to solve the interconnect timing problem on a 300MHz 128-bit 2-way Superscalar Microprocessor. Because of its practical simple algorithm, the location of over 5700(More)
BACKGROUND Medial collateral ligament tibial avulsion is rare. Consequently, diagnostic criteria and a treatment regimen for medial collateral ligament tibial side avulsions remain to be established. The purpose of this study is to clarify the clinical features of medial collateral ligament tibial side avulsions. METHODS We performed a retrospective(More)
