Implication

Finite element analysis demonstrates optimal knee joint load balancing under 4.5° valgus hypercorrection, indicating an effective surgical target to halt osteoarthritis progression.

Key Points

To evaluate how varying high tibial osteotomy correction angles alter stress distribution across knee articular cartilage and identify the optimal angle for balanced compartment loading.
Constructed a three-dimensional finite element model of the human knee joint validated against existing experimental and numerical benchmarks.
Simulated high tibial osteotomy alignment adjustments across a range of correction angles from 0° to 10° valgus.
Increasing valgus correction from 0° to 10° progressively shifted mechanical stress from the medial compartment to the lateral compartment, decreasing both Von Mises and shear stresses medially.
A valgus hypercorrection of 4.5° achieved optimal balanced stress distribution across both compartments, effectively unloading diseased medial cartilage.
