Table 7 Comparison of functional knee score indexes of patients with four PCO changes 1 year before and after TKR

From: Effect of femoral posterior condyle offset on knee joint function after total knee replacement: a network meta-analysis and a sequential retrospective cohort study

  PCO ≤ − 2 mm (n = 25) − 2 mm < PCO < 0 mm (n = 43) 0 mm ≤ PCO < 2 mm (n = 27) PCO ≥ 2 mm (n = 8) p value
Flexion contracture (°) − 5.37 1.12 − 5.07 0.64 − 5.71 0.95 − 5.20 0.71 0.030*
Further flexion (°) 3.81 2.47 4.68 2.31 6.93 3.80 4.26 1.84 < 0.001
WOMAC score − 81.80 8.77 − 79.44 8.26 − 83.52 9.83 − 81.50 8.07 0.300
KS knee score 43.88 7.19 42.00 7.83 47.41 4.35 44.38 11.73 0.032*
KS function score 20.80 10.01 24.91 7.12 26.89 5.82 25.25 6.84 0.038*
  1. The measurement data (mean ± standard deviation) were analyzed using one-way ANOVA. *p < 0.05 indicated significant difference in the four PCO changes
