| Abstract | The strain distribution occurs on femoral bone while the loads transfer from proximal to distal part. The bone may be fracture after received more strain than 25,000 microstrain. Notching of the anterior femoral cortex after total knee arthroplasty can occur when making an anterior femoral bone cut. The notch of bone makes the stress concentration and transform to strain that should make the bone fracture. This study aims to vary the notch size with 3 depths as 1.5, 2.5 and 3.5 mm. and evaluate the strain distribution on the notch with finite element method under daily activities load to find the notch effect to strain distribution on Thai femoral bone. The result showed that the maximum strain occur 1,530 and 1,830 microstrain under walking and stair-climbing respectively. The rise of depth notch tend to increase the maximum strain on the femoral bone, which the surgeon will be avoid this condition for a good clinical result. |
