Abstract:
[Objective]A modified femoral resection method Was introduced for total knee replacement,by which the resection ofthe posterior femoral condyle was increased.This study is to verify the accuracy of resection.[Methods]In 81 knees undergoingtotal knee replacement,the thickness of vKrious cuts were measured and compared with the height of the implants.The mean val-ues of these measurements were calculated,and eompqrisons were made according to the mechanical axis using Student's t-test.[Results]On average,the thickness of bone resection in both the flexion and the extension gap was smaller than the thickness otthe prosthesis.In the varus group a minimum lateral over-resection in the flexion gap Was found,and in valgus group a minimummedial over-resection in the flexion gap was found.[Conclusion]The early clinical results with this modified resection method aregood.
