Seo SS, Kim CW, Lee CR, et al. - Between January 2009 and November 2013, researchers carried out a retrospective analysis on 52 individuals (52 knees) with advanced knee joint arthritis who underwent arthroscopic surgery or two-stage TKA using articulating cement spacer (ACS) for knee joint infection in order to contrast the functional outcomes and recurrence rate of TKA for infected arthritic knees. The infection recurrence rate was greater in the AS vs the ACS-TKA group. About the functional outcomes of the ACS-TKA group obtained during the last follow-up and following conversion to TKA and those of the AS group who underwent TKA following arthroscopic surgery, no important between-group variations were noted. Thus, for people with infected arthritic knees, considering infection control and functional outcomes, two-stage TKA using ACS could be an efficient alternative treatment.
