Impact of Charlson indices and comorbid conditions on complication risk in bilateral simultaneous total knee arthroplasty

Both CCI and ACCI are predictors of post-operative complications with ACCI being the better predictive determinant. Hence, these predictors should be used for risk stratification prior to patient selection for BSTKA. The influence of hypertension, non-ischemic cardiac illness and moderate to severe chronic kidney disease should also be considered during patient selection. Moreover, optimum organ function at the time of surgery should be a priority to avoid these complications.
