Knee Disarticulation Flashcards
increase
2 - 24%
types
supercondylar tendoplasty
gritti-stokes
knee disarticulation
advantages of surgery
less traumatic (decreased bleeding)
end WBing (ideally)
long lever for muscle control
avoid bony overgrowth (peds)
disadvantages of surgery
delayed wound healing –> circulation
advantages of prosthetic
self suspension
distal end bearing/lower socket
decrease need for AD
longer level arm
better fxn all around
disadvantages of prosthetic
prominent femoral condyles
long RL/knee joint distal to socket
foot off the ground in sitting
prominent femoral condyles –> disadvantages
larger socket circumference
single walled socket
socket
similar to TF level
depends on shape of distal RL
suspension/interface
3S w/ strap
solid w/ compressible foam liner in walls
negative pressure suction
knee choice
single axis
knee joint
single pivot (SA) w/ fluid control
polycenturic with fluid or hydraulic (mechanical) swing control
mauch hydraulic
c-leg (micropressor knee)
