TJA in Rare Conditions
- Hemophilia A is a rare genetic disorder involving a deficiency of clotting factor VIII. Coagulation factor replacement therapy has prolonged the life expectancy of patients with hemophilia, but recurrent hemarthrosis of major joints is often a common occurrence. Therefore, orthopaedic adult reconstructive surgeons increasingly encounter hemophilic arthropathy in young adults and consider treating with total joint arthroplasty. In this report, the authors describe a patient with hemophilia A and severe knee osteoarthritis, who was subsequently treated with primary total knee arthroplasty.
- Patients with afibrinogenemia or hypofibrinogenemia present a unique challenge to the arthroplasty surgeon as fibrinogen is a key contributor to hemostasis. Patients with these disorders are known to have a higher risk for postsurgical bleeding complications. We present the case of a patient with hypofibrinogenemia who underwent an elective total knee arthroplasty. Our colleagues in hematology-oncology guided us initially to achieve and maintain appropriate fibrinogen levels in the early perioperative period.
- The opportunity for total joint arthroplasty (TJA) in patients with chronic infectious liver disease is rapidly expanding. This is the product of both superior survival of chronic hepatitis patients, evolving implant technologies, and improvement of techniques in TJA. Unfortunately, treating this group of patients is not without significant challenges that can stem from both intrahepatic and extrahepatic clinical manifestations. Moreover, many subclinical changes occur in this cohort that can alter hemostasis, wound healing, and infection risk even in the asymptomatic patient.
