Abstract

Cementless total knee arthroplasty (TKA) has had limited use in the United States, however, recent reports have demonstrated promising results, but there has been no meta-analysis to examine these outcomes in the past 5 years. In this review, 37 studies (2,940 patients and 3,568 TKAs) were identified and used, comparing cementless to cemented TKA. Pooled implant survivorship was compared using a fixed-effect meta-analysis between cementless and cemented TKA, and between cementless TKA with and without screw fixation. Cementless TKA had implant survivorship comparable to cemented TKA (odds ratio, 1.1; 95% confidence interval [CI], 0.62–2.00). The mean survivorship at 10 years for cementless TKA was 95.6% compared with 95.3% for cemented TKA. At 20-year follow-up, implant survivorship decreased to 76 and 71%, respectively. No difference was observed between fixation with or without screws (OR, 1.1; 95% CI, 0.16–7.5). Implant survivorship for cementless TKA was comparable to the current gold standard cemented TKAs.
