The purpose of this study was to determine how much sagittal rotation of the femoral component affects the flexion gap and femoral component sizing using a computer-simulation technique. The study comprised 25 knees scheduled for total knee arthroplasty (TKA). The femoral component was positioned at -2°, 0°, 2°, 4°, or 6° of flexion to the anterior femoral(More)
BACKGROUND The middle one-third of the tibial crest in the coronal plane and the fibula in the sagittal plane are known as landmarks for extramedullary guides in total knee arthroplasty (TKA). However, there are few foundational anatomic studies about them. We conducted this study to confirm whether these landmarks are reliable. METHODS We evaluated 100(More)
BACKGROUND Lymph node (LN) metastasis is common in papillary thyroid microcarcinoma (PTMC). The aim of this study was to investigate the impact of LN metastasis and its risk stratification on PTMC recurrence. METHODS We retrospectively reviewed the data of 336 patients with PTMC who underwent surgery from 2005 to 2006 at a single institution. LN(More)
Stepwise multiple regression analysis (forward method) was performed with 22 gait variables obtained from the free and slow gait of 35 normal controls (women without knee arthropathy). These 22 variables were target variables, and velocity, age, body height, and body weight were explanatory variables. Velocity showed the greatest effect on the gait(More)
In cases of follicular neoplasm identified by thyroid fine-needle aspiration (FNA), surgery is required to achieve a precise diagnosis. We investigated potential clinical factors for the preoperative prediction of malignancy in thyroid nodules with a cytological diagnosis of follicular neoplasm. We retrospectively reviewed the data of 97 patients who were(More)
PURPOSE The purpose of this study was to compare the uptakes and diagnostic accuracies between 3'-deoxy-3'-[(18)F]fluorothymidine (FLT) and O-(2-[(18)F]fluoroethyl)-L-tyrosine (FET) PET in patients with a clinical suspicion of having a recurrence of glioma after multimodality treatment. METHODS Thirty-two patients who underwent FLT and FET PET due to(More)
We aimed to discriminate subgroups according to the risk of brain metastases in patients with non-small cell lung cancer (NSCLC) lacking neurological symptoms. We performed a retrospective review of 433 patients with NSCLC who underwent chest computed tomography (CT), brain magnetic resonance imaging (MRI) and bone scans at an initial staging work-up(More)
In recent years, increasing interest has been centered on the biochemistry and physiology of the skin surface, in particular, its potential for resisting physical, chemical, and microbiologic challenges. Morphologically, the skin surface is composed of the stratum corneum, sweat and sebaceous gland ducts, and hair follicles that open onto the surface(More)
The aim of this study was to determine how much a distal femoral cutting error would affect the flexion-extension gap difference (flexion gap minus extension gap) in total knee arthroplasty (TKA). We evaluated 15 knees using a computer-simulation technique. Bone cutting errors of -2°, 2° and 4° of extension were simulated in three TKA systems. A distal(More)
