Purpose: Plasminogen activator inhibitor 1 (PAI-1) is a critical enzyme that regulates coagulation and fibrinolytic systems. The aim of this study was to determine the role of PAI-1 4G/5G polymorphism in nontraumatic avascular necrosis of the lunate.
Methods: The study included 45 patients with Kienböck disease and 45 healthy individuals as a control group.
