We carried out an anthropometric analysis using three dimensional computer tomographic measurements of the cut surface of the proximal tibia in 200 knees that were obtained from 50 male and 50 female Korean cadavers. We measured the mediolateral (ML), middle anteroposterior (AP), medial and lateral anteroposterior dimensions and the aspect ratio (ML/AP) of(More)
Unicompartmental knee arthroplasty (UKA) has regained popularity in recent years. However, limited data exist on how UKA affects knee biomechanics. The role of the anterior cruciate ligament (ACL) after fixed bearing UKA remains controversial. In this study, a robotic testing system was used to apply a quadriceps/hamstrings load to cadaveric knee specimens(More)
PURPOSE The aim of this study was to investigate the ability of a new surface-modified denture resin to reduce adhesion of Candida albicans to the denture surface. This material has a negative charge incorporated by copolymerization of methacrylic acid to methyl methacrylate. An in vitro system was designed to assess the adhesion of C. albicans to(More)
This study was aimed to compare robotic-assisted implantation of a total knee arthroplasty with conventional manual implantation. We controlled, randomized, and reviewed 72 patients for total knee arthroplasty assigned to undergo either conventional manual implantation (excluding navigation-assisted implantation cases) of a Zimmer LPS prosthesis (Zimmer,(More)
Although a recent study (Zhang et al. Cell Death Differ 2002; 9; 790-800) presented that acetylcholinesterase (AChE) might be an important common component in leading to various types of apoptosis, the molecular mechanism, by which AChE functions, had remained elusive before that study. We explored the role of AChE in apoptosis by silencing the AChE gene.(More)
OBJECTIVES The purpose of this study was to investigate an optical solution to eliminate the undesirable shine-through effect of implants on peri-implant mucosa by selecting an optimized implant neck color based on an objective and quantifiable method. MATERIAL AND METHODS The optical effect of color strips on 15 peri-implant mucosal sites of 14 patients(More)
BACKGROUND An analysis of contemporary total knee arthroplasty reveals that, on the average, patients rarely flex the knee beyond 120 degrees. The biomechanical mechanisms that inhibit further flexion after total knee arthroplasty are unknown. The objective of the present study was to investigate the capability of a single design of a fixed-bearing,(More)
Altered patellofemoral joint contact pressures are thought to contribute to patellofemoral joint symptoms. However, little is known about the relationship between tibiofemoral joint kinematics and patellofemoral joint contact pressures. The objective of this paper was to investigate the effect of tibiofemoral joint kinematics on patellofemoral joint(More)
OBJECTIVE The objective of this study was to investigate whether regions of cartilage in the tibiofemoral joint where cartilage-to-cartilage contact occurred was thicker than other regions. DESIGN In vivo human subjects. BACKGROUND The thickness of the cartilage in the knee has been investigated in various studies. However, the factors that influence(More)
Evodiamine is one of the major bioactive compounds that have been isolated and purified from the fruit of Evodiae fructus. Evodiamine exhibits antitumor activities against the human tumor cells, including multidrug-resistant tumor cells. However, the molecular mechanism involved in cell death induced by evodiamine treatment remains poorly understood. In the(More)
