Numerical analysis of the effects of material parameters on the lubrication mechanism for knee prosthesis
(Taylor & Francis Ltd, 2006-03)
The tibial component of current knee prostheses made of Ultra Hig Molecular Weigth Polyethylene (UHMWPE) has a high degree of wear that causes knee inflammation, prosthesis loosening and and subsequent replacement in no ...
Lubrication model of a knee prosthesis, with non newtonian fluid and porous rough material
(Planta Piloto de Ingeniería Química, 2009-03)
Tibial component of knee prostheses, made of ultra high molecular weight polyethylene (UHMWPE), experiences a high degree of wear and may be expected to last twelve years on average. In this work, a steady state one-dimensional ...
The Phan-Thien and Tanner Model Applied to the Lubrication of knee prosthesis
(American Society of Mechanical Engineers, 2019-08)
This work aims to provide a contribution to determine a proper model for the study of fluid film lubrication for the reduction of knee prostheses failure due to polyethylene wear. The Phan-Thien and Tanner (PTT) rheological ...
Total knee arthroplasty in patients with rheumatoid arthritis
(SOC MEDICA SANTIAGO, 2004)
Background: Approximately 90016 of patients with rheumatoid arthritis (RA) will have one or both knees involved during the course of the disease. Total knee arthroplasty (TKA) allows restoring function and relieving Pain ...
STUDY ON IMPLANT STABILITY IN CEMENTLESS TOTAL KNEE ARTHROPLASTY
(ATHA COMUNICACAO & EDITORASAO PAULO, 2012)
Objetives: Determine the stability of tibial and femoral components of 20 cementless knee arthroplasties with rotating platform. Methods: The 20 patients (20 knees) underwent an analysis of dynamic radiographs with an image ...
Restless legs syndrome in subjects with a knee prosthesis: evidence that symptoms are generated in the periphery
(Faculdade de Medicina / USP, 2011-01-01)
OBJECTIVE: There are no data adressing the prevalence of restless legs syndrome in subjects who have knee prosthesis. Therefore, we conducted a cross-sectional survey of subjects who underwent knee prosthesis surgery. ...
ISOKINETIC EVALUATION OF PATIENTS SUBMITTED TO TOTAL KNEE ARTHROPLASTY
(ATHA COMUNICACAO & EDITORA, 2009)
Objective: In total knee arthroplasty, the minimally-invasive approach has been claimed to enable earlier rehabilitation because it spares the femoral quadriceps muscle. To check the influence of preserving the extensor ...
Revision after early aseptic failures in primary total knee arthroplasty
(SpringerNew YorkEUA, 2009)
