A 30-mm Cemented Stem Extension Provides Adequate Fixation of the Tibial Component in Revision Knee Arthroplasty

Tibial Component in Revision of Total Knee Arthroplasty: Comparison between Cemented and Hybrid Fixation

OBJECTIVE To compare the clinical, radiographic and medium-term follow-up results from two fixation methods for the tibial component in revision procedures on total knee prostheses: cemented (tray and stem) and hybrid (cemented tray and uncemented, nonporous canal-filling stem). METHODS Between August 1999 and November 2005, 30 revision procedures on total knee arthroplasties were performed o...

How Much Bone Cement Is Utilized for Component Fixation in Primary Cemented Total Knee Arthroplasty?

Dear Editor, We read with great interest the timely study by Satish et al., How Much Bone Cement Is Utilized for Component Fixation in Primary Cemented Total Knee Arthroplasty? (1). We applaud the authors, yet we hope they can clarify some points to make this study more applicable to a wider population.

How Much Bone Cement Is Utilized for Component Fixation in Primary Cemented Total Knee Arthroplasty?

Background: No scientific evidence exists regarding the amount of bone cement used and discarded in primarycemented Total knee arthroplasty (TKA). The aim of this study was to identify the exact amount of bone cement utilizedfor component fixation in primary TKA.Methods: In a prospective study carried out at five centers, 133 primary cemented TKAs were performed. One packof 40g Palacos bone cem...

Tibial component rotation in total knee arthroplasty

BACKGROUND Both the range of motion (ROM) technique and the tibial tubercle landmark (TTL) technique are frequently used to align the tibial component into proper rotational position during total knee arthroplasty (TKA). The aim of the study was to assess the intra-operative differences in tibial rotation position during computer-navigated primary TKA using either the TTL or ROM techniques. The...
