Outcomes of primary total joint arthroplasty after lung transplantation.

Abstract

Lung transplantation is increasingly common with improving survival rates. Post-transplant patients can be expected to seek total hip (THA) and knee arthroplasty (TKA) to improve their quality of life. Outcomes of 20 primary total joint arthroplasties (15 THA, 5 TKA) in 14 patients with lung transplantation were reviewed. Clinical follow-up time averaged 27.5 and 42.8 months for THA and TKA respectively. Arthroplasty indications included osteonecrosis, osteoarthritis, and fracture. All patients subjectively reported good or excellent outcomes with a final average Harris Hip Score of 88.7, Knee Society objective and functional score of 92.0. There were 4 minor and 1 major acute perioperative complications. 1 late TKA infection was successfully treated with two-stage revision. The mortality rate was 28.5% (4/14 patients) at an average 20.6 months following but unrelated to arthroplasty. Overall, total joint arthroplasty can be safely performed and provide good functional outcomes in lung transplant recipients.
