Surface pretreatment for prolonged survival of cemented tibial prosthesis components: full- vs. surface-cementation technique
BACKGROUND One of few persisting problems of cemented total knee arthroplasty (TKA) is aseptic loosening of tibial component due to degradation of the interface between bone cement and metallic tibial shaft component, particularly for surface cemented tibial components. Surface cementation technique has important clinical meaning in case of revision and for avoidance of stress shielding. Degrad...
متن کاملTibial component fixation with cement: full- versus surface-cementation techniques.
Despite excellent outcomes with cemented tibial components in total knee arthroplasty, it still is debated whether the tibial stem should be cemented and what the optimal tibial stem design should be. Proponents of full cementation of the tibial stem and component state that better short-term and long-term component fixation is achieved when full cementation is used. Advocates for surface cemen...
متن کاملFull versus surface tibial baseplate cementation in total knee arthroplasty.
The use of a keel in the tibial component during modern primary total knee arthroplasty (TKA) has become common, and its cementation may affect the future performance of the prosthesis. Although proponents of cementing the entire tibial component argue that this technique provides better initial fixation and may prevent aseptic loosening, reasons exist to apply cement only to the tibial basepla...
متن کاملSurface vs. Implanted Emg for Multifunctional Prosthesis Control: Pilot Results
It has been hypothesized that, due to the potential to both provide a larger number of independent control sites and selectively record from forearm muscles (in particular the deep muscles), intramuscular EMG should be advantageous for multifunctional prosthesis control [1]. The use of surface electromyograms (EMG) to control a multiple degree-of-freedom prosthesis has been investigated for sev...
متن کاملTooth surface treatment strategies for adhesive cementation
PURPOSE The aim of this study was to evaluate the effect of tooth surface pre-treatment steps on shear bond strength, which is essential for understanding the adhesive cementation process. MATERIALS AND METHODS Shear bond strengths of different cements with various tooth surface treatments (none, etching, priming, or etching and priming) on enamel and dentin of human teeth were measured using...
