摘要：

Background: The ideal fixation for modern tibial components in total knee arthroplasty (TKA) remains controversial with uncertainty on whether cementless implants can yield equivalent outcomes to cemented fixation in early follow-up. Methods: A series of 70 consecutive cases with reverse hybrid cementless fixation were matched to 70 cemented cases from 2008 to 2015 based on implant design and patient demographics. Results: Cementless TKA demonstrated greater aseptic loosening (7 vs 0, P=.013) and revision surgery (10 vs 0, P=.001) than cemented fixation within 5 years of follow-up, but with no clinically significant differences in outcome scores. Conclusion: It remains unclear whether early aseptic loosening in cementless TKA can be reduced with enhanced adjunct fixation and what proportion of early failure justifies the potential lifelong fixation through biologic ingrowth of cementless tibial components.
