Objective: Comorbidities in patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA) may compromise outcomes with increased hospital stays, re-admission, and mortality rates. We aimed to determine whether chronic kidney disease (CKD) affects post-operative outcomes of patients undergoing total joint arthroplasty (TJA).Methods: To identify studies for this review and meta-analysis, two independent reviewers searched PubMed, Cochrane, EMBASE, and Google Scholar until April 1, 2019, and identified additional studies by manual search of reference lists. Prospective or retrospective studies with quantitative outcomes for patients undergoing TJA were selected. Outcomes were compared between patients with underlying CKD stage ≥ 3 or eGFR < 60 mL/min/1.73 m2 versus mild/non-CKD as controls. Main endpoints were mortality, re-operation, and re-admission rates.Results: Among 59 studies reviewed, 19 meeting the eligibility criteria were included, providing data of 2,141,393 patients. After THA or TKA, CKD was associated with higher mortality risk than non-CKD (pooled OR 2.20, 95%CI = 1.90 to 2.54; P < 0.001); no significant differences were seen in re-operation between CKD and non-CKD patients (pooled OR 1.26, 95%CI = 0.84 to 1.88; P = 0.266); and CKD patients had higher any-cause re-admission rates (pooled OR = 1.57, 95%CI = 1.27 to 1.94, P < 0.001).Conclusion: Underlying CKD predicts adverse outcomes after elective TJA with increased risk of mortality, re-admission, surgical site infection, and perioperative transfusion. Findings of this review and meta-analysis highlight CKD as a critical contributor to complications after TJA and may be helpful to surgeons when advising patients about associated risks of TJA.
