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 .
Combined effects of a valgus knee brace and lateral wedge foot orthotic on the external knee adduction moment in patients with varus gonarthrosis.
OBJECTIVE To test the hypothesis that a custom-fit valgus knee brace and custom-made lateral wedge foot orthotic will have greatest effects on decreasing the external knee adduction moment during gait when used concurrently . DESIGN Proof-of-concept , single test session , crossover trial . SETTING Biomechanics laboratory within a tertiary care center . PARTICIPANTS Patients ( n=16 ) with varus alignment and knee osteoarthritis ( OA ) primarily affecting the medial compartment of the tibiofemoral joint ( varus gonarthrosis ) . INTERVENTIONS Custom-fit valgus knee brace and custom-made full-length lateral wedge foot orthotic . Amounts of valgus angulation and wedge height were tailored to each patient to ensure comfort . MAIN OUTCOME MEASURES The external knee adduction moment ( % body weight [BW]*height [ Ht ] ) , frontal plane lever arm ( cm ) , and ground reaction force ( N/kg ) , determined from 3-dimensional gait analysis completed under 4 r and omized conditions : ( 1 ) control ( no knee brace , no foot orthotic ) , ( 2 ) knee brace , ( 3 ) foot orthotic , and ( 4 ) knee brace and foot orthotic . RESULTS The reduction in knee adduction moment was greatest when concurrently using the knee brace and foot orthotic ( effect sizes ranged from 0.3 to 0.4 ) . The mean decrease in first peak knee adduction moment compared with control was .36 % BW*Ht ( 95 % confidence interval [ CI ] , -.66 to -.07 ) . This was accompanied by a mean decrease in frontal plane lever arm of .59 cm ( 95 % CI , -.94 to -.25 ) . CONCLUSIONS These findings suggest that using a custom-fit knee brace and custom-made foot orthotic concurrently can produce a greater overall reduction in the knee adduction moment , through combined effects in decreasing the frontal plane lever arm
