摘要：

Objectives: We assessed the accuracy of an extramedullary guide system for femoral component alignment in TKA. Methods: We retrospectively analysed 87 total knee arthroplasties using a newly developed extramedullary guide system. Results: Correct postoperative coronal plane femoral component, with deviation from neutral alignment by 3 degrees or less, was found in 87% of the study population. The percentages were 100%, 91% and 79% for HKA of 0-3 degrees, 3-10 degrees and >10 degrees respectively. Conclusion: The correct use of the extramedullary guide system allows the restoration of the neutral mechanical axes of the lower limb, especially in cases of limited varus deformity.
