Abstract

Simultaneous bilateral unicompartmentsl knee arthroplasty (BUKA) is considered safe and effective. We performed a systematic review to assess the postoperative outcomes. The US National Library of Medicine (PubMed/MEDLINE), Google Scholar, and the Cochrane Database of Systematic Reviews were queried for publications. Ten articles were included with 765 simultaneous BUKA. Overall complication rate was 7.0%, survivorship was 97.6% at mean 17 months follow-up. No differences were reported between simultaneous and staged BUKA. Simultaneous BUKA is as safe as staged BUKA, it is associated with decreased length of stay and operative time, although it has an increased rate of blood transfusion.
