All-polyethylene versus metal-backed and stemmed tibial components in cemented total knee arthroplasty. A prospective, randomised RSA study.
We studied the quality of fixation of the tibial component using radiostereometric analysis (RSA) in 40 patients who had undergone a cemented Freeman-Samuelson total knee arthroplasty. They were prospectively randomised to either a stemmed metal-backed (MB) or non-stemmed all-polyethylene (AP) tibial component. The articulating geometry of the implants was identical, as was the operative techni...
متن کاملMetal-backed versus all-polyethylene tibial components in primary total knee arthroplasty
BACKGROUND AND PURPOSE The choice of either all-polyethylene (AP) tibial components or metal-backed (MB) tibial components in total knee arthroplasty (TKA) remains controversial. We therefore performed a meta-analysis and systematic review of randomized controlled trials that have evaluated MB and AP tibial components in primary TKA. METHODS The search strategy included a computerized literat...
متن کاملMetal-backed versus all-polyethylene unicompartmental knee arthroplasty
OBJECTIVES Up to 40% of unicompartmental knee arthroplasty (UKA) revisions are performed for unexplained pain which may be caused by elevated proximal tibial bone strain. This study investigates the effect of tibial component metal backing and polyethylene thickness on bone strain in a cemented fixed-bearing medial UKA using a finite element model (FEM) validated experimentally by digital image...
متن کاملMetal-backed and all-polyethylene tibial components in total knee replacement.
One hundred seventy-five patients with 243 consecutive primary Press Fit Condylar cruciate-substituting total knee replacements were evaluated at a mean of 5.5 years. One hundred thirteen knees had modular metal-backed tibial components and 130 had all-polyethylene tibial components. The mean knee score and functional score for the patients with unrevised components was not significantly differ...
متن کاملA Functional and Roentgenographic Preliminary Comparative Study Using Metal-backed and All-polyethylene Tibial Components in Total Knee Arthroplasty
OBJECTIVE To describe and clinically and radiographically compare patients who underwent total knee arthroplasty (TKA) with all-polyethylene (ALP) and metal-backed (MTB) tibial implants. METHODS Patients who underwent TKA between January 1988 and December 2004 were grouped according to the type of implant received: all-polyethylene or metal-backed. Sixty patients came for evaluations, totalin...
