CONCLUSION Lateral wedge insoles cause small reductions in the EKAM and KAAI during walking in people with medial knee OA .
Current evidence demonstrates that lateral wedge insoles appear ineffective at attenuating structural changes in people with medial knee OA as a whole and may be better suited to targeted use in biomechanical phenotypes associated with larger reductions in knee load
OBJECTIVE Lateral wedge insoles are intended to reduce biomechanical risk factors of medial knee osteoarthritis ( OA ) progression , such as increased knee joint load ; however , there has been no definitive consensus on this topic .
The aim of this systematic review and meta- analysis was to establish the within-subject effects of lateral wedge insoles on knee joint load in people with medial knee OA during walking .
Effects of a modified shoe on knee load in people with and those without knee osteoarthritis.
OBJECTIVE To evaluate the effects of a modified shoe that incorporates both lateral wedging and a variable-stiffness sole on knee joint loading in 3 population s : individuals with symptomatic and radiographic knee osteoarthritis ( OA ) , asymptomatic overweight individuals , and asymptomatic healthy weight individuals . METHODS Ninety participants ( 30 per group ) underwent a 3-dimensional gait analysis  across 3 test conditions : modified shoes , st and ard control shoes , and barefoot . For each condition , the first peak knee adduction moment ( KAM ) and knee flexion moment ( KFM ) ( both expressed as Nm/[body weight × height]% ) as well as the KAM impulse ( expressed as Nm.s/[body weight × height]% ) were determined . RESULTS The modified shoes significantly reduced the peak KAM as compared to the control shoes in both the OA ( P = 0.002 ) and the overweight ( P = 0.03 ) groups . In the OA group , there was no significant difference in peak KAM when walking in the modified shoe as compared to walking barefoot . In the overweight and the healthy weight groups , the peak KAM when walking in the modified shoe was significantly higher than that when walking barefoot ( P < 0.001 ) . Irrespective of group , the KAM impulse was significantly reduced when walking in the modified shoe as compared to the control shoe ( P < 0.001 ) and was significantly higher during both shoe conditions as compared to walking barefoot ( P < 0.001 ) . There was no change in the KFM between walking conditions for any group . CONCLUSION The findings illustrate that a shoe incorporating both a lateral wedge and a variable-stiffness sole can significantly reduce medial knee joint load . Further research examining the effects of these shoes on pain , function , and structural changes in the joint is warranted
