Don't Just give Push Knee brace as the night splint in FFD in B/L T K R instead make them walk with knee braces to get the dynamic stretch and persistent results

Commonly Push Knee brace as the night splint to correct the Fixed flexion deformity { FFD} in B/L total knee replacement { T K R}. we do knee mobilization and stretching and get the improvement in the extension range but the improvement doesn't last for long time. So commonly push knee braces are used to correct and maintain it.
i get many references of gait training and correction of FFD in TKR. I don't just advice them to use it as night splint or put on when YOU are taking rest but  instead i make them walk with knee braces to get the dynamic stretch during the complex activity of walking. walking with knee brace helps in giving repeated stretch to knee flexion deformity during each stance. and this dynamic stretching happens in the weight bearing position. every time they walk in home they get repetitive stretch and correction of deformity.and this helps in improvement which lasts longer and persistent.
