In our published study, Table 1 incorrectly states the total number of contemporary TKAs in the 17 studies published between 2001 and 2013. The correct total of contemporary TKAs is 1,834. The correct total number of rotating-platform TKAs is 930. The correct total number of fixed-bearing TKAs is 904.
