Use spica bandaging to ensure even pressure.
To avoid too much pressure on certain bony parts (for example the tibia ridge, the rotula) as well as ensuring containment within concave areas, it may be necessary to use cotton wool pads around contoured parts.
Special care must be taken with diabetics and particularly patients with sensitivity disturbances. The bandage must avoid the rotula and small cotton wool pads may be needed around the tibia ridge. This must be frequently monitored.
Bandaging a femoral stump requires fairly long bandages.

Classic bandage.

The bandage must avoid putting pressure on the edges of the scar.

Flaps of flesh may be resorbed if the pressure is correctly applied.

Cross section of a knee disarticulation stump.
For anatomical reasons it is not possible to obtain uniform compression on the stump. There is a risk of necrosis of the rotula and the condyles of the femur.
Foam or cotton wool pads placed around prominent parts permit a uniform compression.
