Fassihi SC, Gu A, Wessel LE, et al. - This study was attempted to ascertain whether knee arthroscopy prior to unicompartmental knee arthroplasty (UKA) is associated with increased rates of UKA failure or conversion to total knee arthroplasty (TKA). Researchers obtained data from the Humana insurance database from 2007-2017. A total of 8,353 UKA patients were included in the study. The findings indicated that knee arthroscopy within two years of UKA is correlated with an elevated rate of UKA conversion to TKA and a higher rate of UKA failure from aseptic loosening. Further research is required to better define these findings, although clinicians should be mindful of this association when performing knee arthroscopy in patients who may be indicated for future UKA.
