The effect of axial rotation between the femoral neck and ankle joint (total [TR]) on normal knees is unknown. Therefore, this study aimed to investigate TR knee kinematics. Volunteers were divided into groups large (L), intermediate (I), small (S), using hierarchical cluster analysis based in standing position. was measured three-dimensional (3D) bone models generated from CT. A two-dimensional 3-dimensional registration technique used assess spatial position femur tibia orientation during...
Case: A 75-year-old woman underwent cruciate retaining total knee arthroplasty (TKA) for osteonecrosis of the knee, converted from unicompartmental due to an intraoperative medial tibial plateau fracture. Four years later, she experienced persistent pain. Computed tomography revealed malalignments in 2 planes. In vivo kinematic analysis using single-plane fluoroscopy, which can visualize femorotibial contact, indicated varus thrust with lateral subluxation component and femoral recessing...
Abstract Introduction Patient satisfaction is an important outcome of total knee arthroplasty (TKA). However, we cannot predict how and why patients are satisfied or dissatisfied with TKA. The hypothesis this study was that patient-reported outcomes (PROs) correlate in vivo kinematics after Materials methods One hundred knees were analyzed deep bending motion estimated from single-plane fluoroscopy using a two-to-three-dimensional registration technique. Active flexion, femoral rotation...
Purpose: The impact of postoperative nutritional status on clinical outcomes and biomechanics following total knee arthroplasty remains largely unknown. This study aimed to assess this question using the prognostic index evaluate orthopedic participants.Methods: Patients with osteoarthritis who underwent (n=49) in Japan were divided into two groups based their 1-week index. Group L patients had a <40, whereas H comprised ≥40. Postoperative improvements Knee Injury Osteoarthritis Outcome...
Aim The purpose of this study is to investigate the three-dimensional (3D) kinematics preoperative osteoarthritic (OA) knees, and clarify validity findings in comparison with previous studies normal OA knees. Materials methods Fifteen knees were scanned by 3D computed tomography (CT) at three positions. We created bone models quantitatively evaluated motion knee joint using a markerless volume-based registration technique. Assessment categories comprised rotation angles anterior–posterior...
Glucocorticoid-induced osteoporosis (GIOP) lacks fully effective treatments. This study investigated the role of Piezo1, a mechanosensitive ion channel component 1, in GIOP. We found reduced Piezo1 expression cortical bone osteocytes from patients with GIOP and mouse model. Yoda1, agonist, enhanced mechanical stress response mass strength, which were diminished by dexamethasone (DEX) administration mice. RNA-seq revealed that Yoda1 elevated activating key transcription factor Hes1, followed...

Summary Background and Objective Inhaled corticosteroids ( ICS ) inhaled combined with long‐acting beta2‐agonist / LABA are standard treatments for asthma. However, factors that might help reduce medication in well‐controlled asthma unknown. We classified problems of patients into biological, psychological adherence factors, investigated associated the indication failure a step‐down treatment. Methods Two hundred twenty two receiving or were assessed physical psychiatric followed up one year...
Few studies have been reported about kinematic comparison between bicruciate stabilized and cruciate retaining total knee arthroplasty with the same anatomical surface geometry. The aim of this study was to demonstrate in vivo kinematics postoperative patient-reported outcomes these two surgeries We analyzed 17 18 arthroplasties using single-plane fluoroscopic surveillance two- three-dimensional registration techniques during squatting from minimum maximum flexion. Flexion angle, femoral...
<title>Abstract</title> <bold>Background: </bold>The single-radius design is one of the major total knee arthroplasty (TKA) designs and widely used all over world. The objective this study was to compare in vivo kinematics between anteroposterior (AP) with mediolateral (ML) (Non Restricted Geometry; NRG) ML dual-radius (Triathlon) during stair activities. <bold>Methods: </bold>A 21 knees 18 patients (NRG group: 10 7 patients, Triathlon 11 patients) a clinically successful posterior...
Abstract This study analyzed 31 patients with symptomatic osteoarthritic knees scheduled to undergo knee arthroplasty or high tibial osteotomy and demonstrated shape variations in their proximal tibia using an average three-dimensional (3D) bone model. Preoperative computed tomography of the affected was reconstructed as 3D models a triangle mesh surface layers. The initial case defined template, other were into homologous same number vertices that template. corresponding averaged evaluate...
The medial preserving gap technique has recently been used in total knee arthroplasty. Generally, the deep collateral ligament (DMCL) is released using this technique. However, effect of DMCL release on kinematics and length ligaments remains unknown. This study aimed to clarify how affects change during high flexion movements. Three cadaveric knees were examined a computed tomography-based navigation system. following parameters evaluated: femoral rotation varus-valgus angle relative tibia;...
Introduction: Whether the kinematics of cadaveric knees recreate those patient's after total knee arthroplasty (TKA) remains unknown. This study compared in vivo and vitro fluoroscopic TKA during bending using same implant design. Methods: Patients who had undergone cruciate-retaining cruciate-substituting (CR-TKA CS-TKA) did squatting motions. Fresh-frozen human were tested under dynamic closed-chain extension an Oxford rig. Fluoroscopic measured a 2-dimensional to 3-dimensional...
Abstract Mobile-bearing (MB) unicompartmental knee arthroplasty (UKA) has high conformity between the femoral articular surface and meniscal bearing; therefore, subsurface contact stress is reduced. Additionally, survival rate high. However, in vivo kinematics of MB UKA knees during high-flexion activities daily living remain unknown. The aim this study was to investigate three-dimensional living. A total 17 patients who could achieve kneeling after were examined. Under fluoroscopy, each...
