OR Odds ratio, CI Confidence interval, PPFx Periprosthetic fracture, SSI Surgical site infection, PJI Periprosthetic joint infection. Definitions: N/A Not Applicable. Odds ratio and confidence intervals were not calculable due to zero event rates in both groups or insufficient data for statistical analysis. < 11: Event rates less than 11 are not reported due to database privacy policies to prevent potential identification of patients
