Long-term implant survivorship of cementless total knee arthroplasty: a systematic review of the literature and meta-analysis

This report has been verified by one or more authors of the original publication.

37 articles were included in this systematic review and meta-analysis investigating survivorship of cementless component in total knee arthroplasty (TKA). Four RCT's were available for meta-analysis comparing cementless and cemented fixation in total knee arthroplasty. Pooled survivorship for various postoperative time intervals up to a minimum of 10 years was consistently 95% or higher, and meta-analysis of RCTs demonstrated no significant difference in survivorship between cementless and cemented fixation. Supplementary screw fixation did not exhibit a significant impact on cementless TKA survivorship rates.
