Knee disarticulation leaves a long femoral lever and a bone end that can bear load directly. This lets the socket self-suspend over the condyles and transfer weight through the distal limb, sparing the groin.

The challenge is length: a conventional mechanical knee makes the prosthetic thigh sit longer than the sound side. We use a low-profile polycentric knee to keep the knee centres level and the gait symmetrical.

It is also the preferred level in children because it preserves the distal femoral growth plate, so the limb grows closer to normal and bony overgrowth is reduced.
