Fig. 1From: Native knee kinematics is not reproduced after sensor guided cruciates substituting total knee arthroplastyAnalysis of knee flexion during Gait Cycle. A Heel-strike: both groups (PS TKA and healthy controls) showed a slight flexion contracture at heel-strike. The difference between the two groups was not statistically significant. B Mid-stance flexion angle. There was a trend that the average mid-stance knee flexion angle in the bi-cruciate substituting PS TKA group (16.1°) was lower than the healthy controls group (20.7°) (P = 0.07)Back to article page
