Patients with a knee disarticulation have a lengthened
thigh and subsequent shortened lower leg due
to the knee device built at the end of the upper leg.
We show that the amount of thigh lengthening varies
between 23 and 92 mm, depending on the knee device
used, while lower leg shortening varies between
3 and 50 mm. The most favorable knee devices are polycentric, whereas microprocessor-controlled knees
show less favorable characteristics because of their
extended lengthening of the thigh.
