Cerebrovascular disease is associated with outcomes after total knee arthroplasty: a US total joint registry study.

Abstract

We assessed the association of cerebrovascular disease preoperatively with patient-reported outcomes (PROs) of moderate-severe activity limitation and moderate-severe pain at 2- and 5-years after primary total knee arthroplasty (TKA) using multivariable-adjusted logistic regression; 7139 primary and 4234 revision TKAs were included. Compared to the patients without cerebrovascular disease, those with cerebrovascular disease had a higher odds ratio (OR) of moderate-severe limitation at 2 years and 5 years, 1.32 (95% confidence interval [CI]: 1.02, 1.72; P = .04) and 1.83 (95% CI: 1.32, 2.55; P < .001), respectively. No significant associations were noted with moderate-severe pain at 2 years or 5 years. In conclusion, we found that cerebrovascular disease is independently associated with pain and function outcomes after primary TKA. This should be taken into consideration when discussing expected outcomes of TKA with patients.
