Total knee arthroplasty: A single centre review at 10 years of follow-up

Abstract

Background: Total knee arthroplasty is a common procedure for treatment of various non-infective arthritis. This study reviewed total knee arthroplasty cases up to 10 years of follow-up for the survival rate, reasons of revision and associated perioperative risk factors for revision. Methods: All cases to total knee arthroplasty performed in a single centre in the years 2007 and 2008 were reviewed. A total of 227 cases of total knee arthroplasty were performed during the 2-year period, with 156 cases followed up to 10 years. Perioperative information, follow-up information and information of possible complications were obtained. Results: The survival rate of total knee arthroplasty in this study is 98.2% at 5 years and 94.2% at 10 years of follow-up. The early post-operative complication rate was low, and majority of cases had improvement of function at 1 year after the operation. Early post-operative infection rate was low at 0.4%, and overall infection up to 10 years of follow-up was also low at 4.4%. Ten cases had undergone revision of arthroplasty by 10 years after operation. Conclusion: The survival rate of total knee replacement was high. The revision rate and infection rates were low up to 10 years of follow-up. The most common reasons of revision arthroplasty were infection and aseptic loosening. Cases which required revision arthroplasty had significantly longer operative duration compared with cases without revision at 10 years of follow-up ( p = 0.01).

Revision total knee arthroplasty longer term outcome and comparison between infection and aseptic loosening at mean follow-up of 10 years

“…In another study from a center with similar demographics, a longer operative team in the initial arthroplasty is related to subsequent revision arthroplasty. 30 In a recent local study, Siu et al 31 stated that gram positive Staphylococcus was most common infective organism. Similarly in this study, infective organism identified were predominately gram positive cocci (Table 2).…”

Roughness Digital Characterization and Influence on Wear of Retrieved Knee Components

“…Failure most commonly occurs due to fatigue and adhesive wear, which are responsible for the generation of micro particulate debris that, in turn, cause osteolysis around the replacements, ultimately leading to loosening and failure of the TKR [7][8][9]. The survival rate of total knee replacements (TKR) has been reported to increase along with the development of advanced technologies and operative techniques [10][11][12].…”
