Patients with stage 1, 2 or 3 chronic kidney disease may have a higher rate of prosthetic joint injection after total joint arthroplasty, according to study results.
Researchers retrospectively reviewed electronic medical records for 377 patients with stage 1 to 2 kidney disease with 402 patients who had stage 3 chronic kidney disease. All patients underwent total hip arthroplasty (THA) or total knee arthroplasty (TKA) between 2004 and 2011.
Patients with stage 3 chronic kidney disease had a greater rate of overall mortality compared with patients with stage 1 to 2 chronic kidney disease, according to the researchers.
When adjusted for comorbid disease, the researchers found no significant increases in joint infection, readmission or early revision between patients with stage 1 to 2 chronic kidney disease compared with patients with stage 3 chronic kidney disease.
Compared with patients with end-stage renal disease, dialysis and kidney transplant, overall incidence of infection was high but much less in chronic kidney disease patients.
In a subgroup analysis, the significant difference in mortality rate persisted between the stage 1 to 2 group vs. the stage 3 group in patients who had undergone THA, but not in patients who had undergone TKA, according to the researchers.
Study results showed a slightly lower rate of 90-day readmission in patients with stage 1 to 2 chronic kidney disease who underwent TKA than in patients with stage 3 chronic kidney disease, whereas 90-day readmission was slightly higher in the THA subgroup.
