ABSTRACT
OBJECTIVE@#To analyze the relationship between the distribution of lower limb alignment and short term clinical efficacy in patients with varus-type osteoarthritis after primary total knee arthroplasty (TKA).@*METHODS@#From December 2016 to March 2018, 87 patients (101 knees) with knee osteoarthritis were treated with the first total knee arthroplasty by the same medical group, including 21 males(25 knees) and 66 females(76 knees), ranging in age from 51 to 85 years old, with a mean of (67.6±7.0) years old. According to the difference of hip knee ankle angle (HKA) after total knee arthroplasty, the patients were divided into 4 groupsneutral position group (group A), -3°≤HKA≤3°, 50 knees;slight varus group (group B), 3°0.05). There was no significant difference in knee joint activity among the 4 groups. The score of femoral prosthesis force line within ±3°was better than that of the other group (0.05).@*CONCLUSION@#The short term clinical efficacy of patients with knee varus osteoarthritis after primary total knee arthroplasty is related to the distribution of lower limbs alignment. The short-term clinical efficacy of slight inversion position can be similar to that of neutral position. The force line distribution of femoral prosthesis is related to the short term clinical efficacy after primary knee arthroplasty.
