Table 6 Comparison of functional knee score indexes of patients with four PCO changes 1 year 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 (°) 0.97 ± 0.46 0.95 ± 0.42 0.57 ± 0.28 0.77 ± 0.23 < 0.001*
Further flexion (°) 120.42 ± 3.11 125.41 ± 2.93 126.87 ± 3.93 123.25 ± 1.46 < 0.001*
WOMAC score 28.76 ± 5.17 28.86 ± 5.79 29.30 ± 5.04 25.00 ± 7.82 0.291
KS knee score 83.24 ± 7.22 82.21 ± 7.24 85.89 ± 3.85 85.38 ± 9.18 0.137
KS function score 70.32 ± 9.29 73.58 ± 6.46 77.26 ± 3.37 75.75 ± 2.87 0.002*
  1. The measurement data (mean ± standard deviation) were analyzed using one-way ANOVA. *p < 0.05 indicated significant difference in the four PCO changes
