Paper #38 Early loosening of the tibial component of the posterior-stabilized insall-burstein knee prosthesisThe purpose of this study was to define the topography of the articular surface of the femoral condyles and to develop a method for computerized topographic matching of donor and recipient ...
Despite excellent results of bicondylar knee resurfacing when both the tibial and femoral components are cemented, loosening of the cemented tibial component (surface cementing) occurs in approximately 10% of the implants within a 4-year interval after the procedure. Based on our own experience, we...
This study's aim was to measure the loosening force of the femoral component in several PS-TKA designs during a simulated deep flexion activity.关键词: Classification Degenerative disc disease Adult thoracolumbar deformity Sagittal balance Adult scoliosis DOI: 10.1007/s00586-014-3219-9 ...
component looseningstress-shieldingfinite element modelingAseptic loosening caused by mechanical factors is a recognized failure mode for tibial components of knee prostheses. This parametric study investigated the effects of prosthesis fixation design changes, which included the presence, length and diameter ...
A series of 100 consecutive UCI knee replacements showed a 7 per cent incidence of reoperation due to loosening of the prosthesis associated with permanent deformation of the tibial component. Analysis of the clinical data, roentgenograms, and removed implants showed associations between failure and...
loosening is a process with aninitial pointthat progresses until the complete loosening of the implant and bone. In some implantations, bone–implant contact surfaces are large with different load transferring mechanisms at the interfaces. For instance, the contact surfaces of the knee tibial tray ...
TO WHAT EXTENT THE COMBINATION OF STEM LENGTH AND STEM INCLINATION DO AFFECT THE PERFORMANCE OF THE TIBIAL COMPONENT IN KNEE IMPLANTS? Mechanical loosening, instability, mechanical fractures and poor quality of bone are some factors that strongly influence the deterioration of knee implant... N Manga...
In this paper, a combined theoretical and experimental investigation is reported with respect to the influence of mechanical loading on the tibial part of implanted hinged knee prostheses with intramedullary stems. The theoretical analys... D. H. Campen,H Croon,J Lindwer 被引量: 1发表: 1979年...
High-viscosity cement (HVC) has been implicated as a possible cause for aseptic loosening of the tibial component. The purpose of this study was to evaluate the incidence of aseptic loosening of the tibial component in obese patients with the use of HVC and standard tibial tray.Crawford, David...
This study investigated whether a short extension stem for the tibial component in severely varus knees would reduce the failure rate due to loosening on the tibial side.Park, Min-hoBin, Seong-IlKim, Jong-MinLee, Bum-SikLee, Chang-RackKwon, Young-Hee...
