Background Clinical outcomes remain largely unknown beyond perioperative and short-term follow-up of solid organ transplant (SOT) patients undergoing total knee arthroplasty (TKA). Methods Patient mortality, implant survivorship, and complications of 96 TKAs (76 patients) after SOT were retrospectively reviewed through an internal joint registry. Mean age at index arthroplasty was 66 years, and mean follow-up was 4 years. Results Overall mortality rates at 1 year, 2 years, and 5 years from TKA were 2.6%, 7.9%, and 13.2%, respectively, and combined SOT patient survivorship was 92% at 2 years and 82% at 5 years. Implant survivorship free of any component revision or implant removal was 98% at 2 years and 93% at 5 years. There was a high rate of perioperative complications (12.5%), including periprosthetic fractures (5.2%) and deep periprosthetic infection (3.2%). Conclusion TKA does not appear to have any effect on SOT patient survivorship following the procedure. However, SOT patients may have a higher risk of perioperative complications and a lower implant survivorship than the general population of TKA patients at midterm follow-up.
