This study aimed to identify the effect of anatomical tibial component (ATC) design on load distribution in the periprosthetic tibial bone of Koreans using finite element analysis (FEA). 3D finite element models of 30 tibiae in Korean women were created. A symmetric tibial component (STC, NexGen LPS-Flex) and an ATC (Persona) were used in surgical simulation. We compared the FEA measurements (von Mises stress and principal strains) around the stem tip and in the medial half of the proximal tibial bone, as well as the distance from the distal stem tip to the shortest anteromedial cortical bone. Correlations between this distance and FEA measurements were then analyzed.Aims

Aims. This study investigated the influence of body mass index (BMI)
on patients’ function and quality of life ten years after total
knee arthroplasty (TKA). Patients and Methods. A total of 126 patients who underwent unilateral TKA in 2006
were prospectively included in this retrospective study. They were
categorized into two groups based on BMI: < 30 kg/m. 2. (control)
and ≥ 30 kg/m. 2. (obese). Functional outcome was assessed
using the Knee Society Function Score (KSFS), Knee Society Knee
Score (KSKS), and Oxford Knee Score (OKS). Quality of life was assessed
using the Physical (PCS) and Mental Component Scores (MCS) of the 36-Item
Short-Form Health Survey. Results. Patients in the obese group underwent
We explored the outcome of staged bilateral total
knee replacement (TKR) for symmetrical degenerative joint disease
and deformity in terms of patient expectations, functional outcome
and satisfaction. From 2009 to 2011, 70 consecutive patients (41
female) with a mean age of 71.7 years (43 to 89) underwent 140 staged
bilateral TKRs at our institution, with a mean time between operations
of 7.8 months (2 to 25). Patients were assessed pre-operatively
and at six and 12 months post-operatively using the Short Form-12,
Oxford knee score (OKS), expectation questionnaire and satisfaction
score. The pre-operative OKS was significantly worse before the
