Whether neutral alignment brings better clinical outcomes is controversial. Consideration of the preoperative knee condition patients and some limitations previous studies, we suggested that other index may be more important than a generic target 0° ± 3° axis to reflect changes in coronal after total replacement (TKR). The purpose this study was explore relationship between functional outcome with new grouping method concept correction rate.The included 358 knees, mean follow-up period 3.62 years. A adopted divide into three groups based on degree mechanical femoral-tibial angle (MFTA): under-correction (n = 128), 209) over-correction 21). Hospital for Special Surgery (HSS) score were compared among 3 (ANOVA or without LSD t-test). In addition, also attempt further whether rate can predict postoperative (Simple linear correlation analysis).HSS showed significant improvement all groups. There no difference HSS (88.27 vs 88 85.62) (p 0.88) incremental scores (26.23 25.22 22.88) 0.25) category MFTA at last follow-up. correlational analyses didn't show any positive results (r -0.01 p 0.95, r 0.97, 0.11 0.15, 0.01 0.90).Categorization optimal TKR impractical. But still believe are worthy research which reflects change alignment. Perhaps it used future.III.
