Footwear modification can beneficially alter knee loading in patients with knee
osteoarthritis. This study evaluated the effect of Masai Barefoot Technology
shoes on reductions in external knee moments in patients with knee
osteoarthritis. Three-dimensional motion analysis was used to examine the effect
of Masai Barefoot Technology versus control shoes on the knee adduction and
flexion moments in 17 women (mean age, 63.6 years) with radiographically
confirmed knee osteoarthritis. The lateral and anterior trunk lean values, knee
flexion and adduction angles, and ground reaction force were also evaluated. The
influence of the original walking pattern on the changes in knee moments with
Masai Barefoot Technology shoes was evaluated. The knee flexion moment in early
stance was significantly reduced while walking with the Masai Barefoot Technology
shoes (0.25+/-0.14Nm/kgm) as compared with walking with control shoes
(0.30+/-0.19 Nm/kgm); whereas the knee adduction moment showed no changes. Masai
Barefoot Technology shoes did not increase compensatory lateral and anterior
trunk lean. The degree of knee flexion moment in the original walking pattern
with control shoes was correlated directly with its reduction when wearing Masai
Barefoot Technology shoes by multiple linear regression analysis (adjusted
R2=0.44, P<0.01). Masai Barefoot Technology shoes reduced the knee flexion moment
during walking without increasing the compensatory trunk lean and may therefore
reduce external knee loading in women with knee osteoarthritis.
