Arthropathy of Knee Joint
Conditions
Brief summary
To compare the functional outcomes of Computer-Assisted Navigation (CAS) and Conventional Instrumentation TKA at the 8-year follow-up.
Detailed description
The data of the present study was collected from the review of the medical chart of the patients who were scheduled to undergo staged bilateral TKA and randomly assigned to receive Computer-Assisted Navigation (CAS) TKA in one limb and conventional TKA. Then, comparing the functional outcomes of CAS and Conventional Instrumentation was performed by statistical software.
Interventions
PROCEDUREComputer-Assisted Navigation TKA
TKAs were performed using the image-free CAS navigation system VectorVision

Secondary
| Measure | Time frame | Description |
|---|---|---|
| Radiographic evaluation | Baseline and 3 months after operation | Standard anteroposterior, lateral radiographs of the knee and standing long-leg radiographs of the lower extremity were obtained pre- and postoperatively. The lower extremities were fully extended so that the tibial tuberosities were facing forward and the lateral malleoli were 15 cm apart to ensure that the tibia was vertical and facing forward with minimal rotation. The X-ray beam (20-25 mA/s; 80-85 kV) was centered at the knee joint level at a distance of 120-140 cm.Radiographic data included the mechanical axis angle and the four component alignments described by Ewald: the femoral valgus (FV) angle; tibial valgus angle (TV); femoral flexion (FF) angle; and tibial flexion angle (TF) |
