Summary
Navigation-aided knee arthrodesis successfully corrected complex femoral deformities. This technique ensured accurate limb alignment, leading to pain-free ambulation and improved function post-surgery.
Area of Science:
- Orthopedic Surgery
- Biomechanical Engineering
Background:
- Complex limb deformities present challenges in achieving accurate surgical alignment.
- Traditional methods may struggle with precise bone cut orientation in cases of significant deformity.
Observation:
- A patient with a complex femoral deformity underwent navigation-aided knee arthrodesis.
- A wireless navigation system guided distal femur and proximal tibia osteotomies in coronal and sagittal planes.
- Bilateral monolateral external fixation was employed for stable arthrodesis.
Findings:
- The navigation system facilitated precise bone cuts, addressing the challenges posed by the complex deformity.
- Post-operatively, the patient experienced complete pain relief and regained unaided ambulation.
- The final mechanical axis of the limb was accurately restored to 180 degrees.
Implications:
- Navigation-aided surgery offers a viable solution for complex knee arthrodesis cases.
- Precise alignment achieved through navigation can significantly improve functional outcomes and patient quality of life.
- This approach may be beneficial for correcting limb deformities and restoring mechanical axis in orthopedic procedures.
