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

## TL;DR

This paper discusses a surgical technique combining bone cement and screws to improve knee replacement outcomes in patients with severe bone loss.

## Contribution

The paper introduces the use of bone cement with screw augmentation in 3D-printed customized total knee arthroplasty for severe bone defects.

## Key findings

- The BCSA technique enhances implant fixation and longevity in patients with tibial and femoral bone defects.
- A clinical case demonstrated excellent imaging and clinical outcomes using the BCSA technique with 3D-printed surgery.
- The BCSA method provides better load distribution and reduces micromotion in compromised bone stock.

## 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.
