- Abstract:
- Objective To investigate the biomechanical changes of the tibial plateau following proximal fibula osteotomy by
three-dimensional finite element analysis for providing biomechanical evidences for the application of proximal fibular
osteotomy in knee osteoarthritis with varus deformity. Methods Based on the CT data of a healthy volunteer, an individual
knee joint finite element model was constructed by Mimics, Geomagic Studio2013 and Abaqus6.13 software. The stress of
any node on different sections of the tibial plateau before and after proximal fibular osteotomy was calculated by setting the
boundary conditions, loading material properties, applying loads and simulating proximal fibular osteotomy in the finite
element model. Results After the surgical removal of the fibular support, the stress of the medial tibial plateau was
inconsistent. The internal stress was reduced and the middle remained unchanged but the lateral was increased. However,
the stress of the lateral tibial plateau was increased, and the internal stress was the maximum. There was a trend that the stress
on the entire tibial plateau was concentrated in the middle. Conclusion Proximal fibular osteotomy is conductive to reducing
the stress on the medial tibial plateau, thus alleviating the pain and inconvenience of patients with knee osteoarthritis. Due to
the postoperative stress redistribution, the long-term efficacy and indications of the operation strategy still need to be further
researched.
