摘要：

We prospectively studied variations in valgus correction angle (VCA) and the influence of preoperative limb deformity on VCA in 503 consecutive total knee arthroplasties done in 393 patients. The percentage of limbs that had VGA values less than 5 degrees was 10.9%, and that with VGA values greater than 7 degrees was 44.9%. The percentage of limbs with VGA greater than 7 degrees was significantly more in varus knees, and that with VGA less than 5 degrees was significantly more in valgus knees; preoperative deformity showed a significant correlation with VGA. Choosing a fixed-routine VGA of 5 degrees to 7 degrees may cause an unacceptable planning error that may be minimized by individualizing VGA or using computer navigation.
