Screening status of all total knee and total hip patients between October 2011 and March 2013 (n = 4,042) who subsequently underwent revision surgery (N = 47). A subgroup analysis of the screened group compared those colonized with MSSA (methicillin-sensitive Staphylococcus aureus) with those who were noncarriers. p values relevant to the subgroup analysis are denoted with an asterisk.
