The bone cement with screw augmentation surgical technique in a 3D-printed customized total knee arthroplasty for a patient with severe bone defect.

ABSTRACT: The bone cement with screw augmentation (BCSA) technique is a valuable adjunct in complex total knee arthroplasty (TKA) cases with compromised bone stock. This surgical strategy enhances fixation in tibial and femoral defects, provides better load distribution, reduces micromotion, and improves the longevity of implants. The aim of this article is to explore the role of the BCSA technique, describe the technique itself, and review its outcomes specifically in the context of TKA. Additionally, we present a clinical case of an 80-year-old female patient with end-stage osteoarthritis and a severe tibial bone defect, who was treated with primary TKA using a 3D-printed cutting technique. The bone defect was managed using the BCSA technique with excellent imaging and clinical outcomes.
