The cementless knee: Intermediate term guarantee on parts and labor

While cemented fixation is the current gold standard in North America, biologic fixation to host bone has the potential for a more durable construct, particularly in young and active patients. Previous failures with cementless TKA constructs have been attributed to design-related issues such as poor tibial ingrowth surfaces, metal-backed patellas, screw track osteolysis, and issues with the polyethylene, including thin inserts and non-conforming articulations. Recent innovations such as tantalum have shown durable and reliable results with contemporary cementless TKAs. Additional advantages include diminished operative times, preservation of bone stock, ease of revision surgery, and elimination of third body wear.
