Area of Science:

Orthopedic Surgery
Biomedical Engineering

Background:

Femoro-tibial alignment is crucial for primary knee prostheses.
The efficacy of navigation in revision knee surgery remains under-evaluated.

Purpose of the Study:

To describe and evaluate a navigation-assisted procedure for knee revision surgery.
To assess the utility of navigation in complex cases with bone loss.

Main Methods:

Bone morphing acquisition of original implants followed by a tibia-first bone cut sequence.
Preoperative CT-scan of the femoral component and intraoperative knee balancing with trial components and original femoral implant in place.
Retrospective comparison of 19 navigated cases with 10 non-navigated cases.

Main Results:

Navigation assisted in reconstructing bone extremities and controlling the joint line level.
No significant difference in outliers between navigated and non-navigated groups.
Procedure demonstrated feasibility in cases with severe bone loss requiring reconstruction.

Conclusions:

Navigation appears to be a valuable tool for knee revision surgery, particularly in complex reconstructions.
Further prospective and comparative studies with larger patient series are required for definitive validation.
