Finite element analysis of the influence of the posterior tibial slope on mobile-bearing unicompartmental knee arthroplasty.

Background: The most common modes of failure reported in unicompartmental knee arthroplasty (UKA) in its first two decades were wear on the polyethylene (PE) insert, component loosening, and progressive osteoarthritis in the other compartment. The rates of implant failure due to poor component positioning in patients who have undergone UKA have been reported. However, the effect of the posterior tibial slope on the biomechanical behavior of mobile-bearing Oxford medial UKA remains unknown.

Biomechanical effect of tibial slope on the stability of medial unicompartmental knee arthroplasty in posterior cruciate ligament-deficient knees.

Aims: Unicompartmental knee arthroplasty (UKA) has become a popular method of treating knee localized osteoarthritis (OA). Additionally, the posterior cruciate ligament (PCL) is essential to maintaining the physiological kinematics and functions of the knee joint. Considering these factors, the purpose of this study was to investigate the biomechanical effects on PCL-deficient knees in medial UKA.

[Assessment of applicability of standardized rates for health state comparison among areas: 2008 Community Health Survey].

Objectives: This study shows the issues that should be considered when applying standardized rates using Community Health Survey(CHS) data.

Methods: We analyzed 2008 CHS data. In order to obtain the reliability of standardized rates, we calculated z-score and rank correlation coefficients between direct standardized rate and indirect standardized rate for 31 major indices.

Emergency medical information system for transferring patients to the medical institute by triage-result.

The Objective of this study was to triage the emergency patients in a pre-hospital stage and transfer them to the appropriate medical institute by the triaged result. For this, considering the pre-hospital emergence situation, we selected the Manchester system as the triage. So we analyzed the components of the ambulance records in Korea, transformed MTS components according to analysis-results of the ambulances and applied them to the information system in using a C# web application.
