Survivorship After Primary Total Hip Arthroplasty in Solid-Organ Transplant Patients.

Overview

BACKGROUND: Although a growing number of primary total hip arthroplasties (THAs) are being performed on solid-organ transplant (SOT) recipients, long-term patient and implant survivorships have not been well studied in contemporary transplant and arthroplasty practices. METHODS: A total of 136 THAs (105 patients) with prior SOT were retrospectively reviewed from 2000 to 2013 at mean clinical follow-up of 5 years. The mean age was 59 years, with 39% being females. The most common SOT was renal (56%), followed by liver (24%). RESULTS: Patient mortality was 3.8% and 13.3% at 2 and 5 years, respectively. There were 9 revisions (6.6%), including 5 (4%) for deep periprosthetic infection. Implant survivorship free of any revision was 95% and 94% at 2 and 5 years, respectively. Transplant type or surgical indication did not significantly impact patient or implant survivorship. CONCLUSION: Compared with the general population, SOT patients undergoing THA have slightly higher mortality rates at 5 years. Implant survivorship free of revision was slightly lower than the general population, primarily due to an increased risk of periprosthetic joint infection.
