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

Table 6 Comparison of functional knee score indexes of patients with four PCO changes 1 year after TKR

	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*

The measurement data (mean ± standard deviation) were analyzed using one-way ANOVA. *p < 0.05 indicated significant difference in the four PCO changes
