From: Effect on inclined medial proximal tibial articulation for varus alignment in advanced knee osteoarthritis

  < 100% of WB passing point (n = 36) ≥100% of WB passing point (n = 66)  
Mean 95% CI Mean 95% CI p value

ΔWB line passing point (%) 12.6 5.2–20.1 32.1 26.7–37.4 < 0.0001*
ΔTibial position (°) 1.1 0.6–1.6 2.5 2.0–3.0 < 0.0001*

  1. MCT = medial compartment in the proximal tibia, WB = weight-bearing, Δ difference = difference in each parameter between non-WB and WB conditions, tibial position = the relative angle of WB line to x–axis in the tibial coordinate system, femoral position = the relative angle of WB line to a surgical epicondylar axis, 95%CI = 95% confidence interval; *Significant difference = p < 0.01
