Background
The knee joint remains the most affected joint in extra-intestinal manifestations of Crohn’s disease (CD). Given the increasing prevalence of CD and overall demand for total knee arthroplasty (TKA), it is likely that an increasing number of patients with CD will require TKA. The purpose of this study was to assess the inpatient postoperative complication in patients with CD undergoing TKA.
Materials and methods
We queried the Nationwide Inpatient Sample (NIS) database between the years of 2016 to 2019, including a total of 558,371 patients who underwent primary TKA. Among these, 1461 were in the CD group and 556,910 were in the non-CD group (controls). Data pertaining to demographics, length of stay (LOS), total healthcare cost, mortality, and in-hospital complications (blood loss anemia, blood transfusion, periprosthetic infection, periprosthetic dislocation, periprosthetic mechanical complication, acute renal failure, myocardial infarction, pneumonia, pulmonary embolism, deep vein thrombosis, superficial/deep surgical site infection, and wound dehiscence) were compared between the two groups.
Results
Patients diagnosed with CD had higher postoperative complications such as blood loss anemia (OR: 1.22, 95% CI: 1.07–1.39, p = 0.004), periprosthetic infection (OR: 1.80, 95% CI: 1.23–2.63, p = 0.006), and the need for blood transfusion (OR: 1.447, 95% CI: 1.01–2.06, p = 0.044) in comparison to the control group. In-hospital mortality and acute renal failure were similar in both groups. The CD group had a significantly prolonged LOS (2.54 vs. 2.35 days, p < 0.001). No statistically significant difference was noted concerning in-hospital charges between the two groups.
Conclusions
CD patients undergoing TKA experienced increased LOS and postoperative complications. However, these complications were minor and did not affect total hospital cost. Further prospective cohort studies could build upon the findings described to continue to maximize outcomes in CD patients undergoing TKA, which might extend to other cohorts.
