Abstract:The purpose of this study was to assess the effects of a less-invasive midvastus exposure during total knee arthroplasty (TKA) on cement mantle grade compared with a standard parapatellar arthrotomy and standard TKA. Fifty consecutive cemented minimally invasive TKAs using a midvastus approach, patellar subluxation without eversion, and less-invasive instrumentation were compared radiographically with a control cohort of 50 consecutive cemented standard TKAs. To eliminate patient selection bias, the standard c… Show more
“…Minimally invasive TKA through the mid-vastus approach has reported to compromise the quality of the femoral cement Table 2 Cement void in different zones of the femoral, tibial, and patellar components in the conventional and computer-assisted minimally invasive total knee arthroplasty (TKA) group mantle and result in a higher rate of tibial cement debris. 17 However, one study reported no progressive radiolucency 6 months after minimally invasive or conventional TKA. 18 In our study, the only variable affecting the quality of cementation was the amount of exposure where minimally invasive TKA resulted in a wider cement void beneath the anterior flange of the femoral component and a higher rate of retained cement in the posterior or lateral aspects of the tibial component.…”
Minimally invasive TKA resulted in a wider cement void beneath the anterior flange of the femoral component and a higher rate of retained cement around the tibial component.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
