مريض بعد بتر تحت الركبة بسبب مرض الشرايين الطرفية. أي وضعية تمنع تيبس الركبة؟

After a below-knee amputation for PAD, which positioning prevents knee contracture?

1. Hang the knee over the edge of the bed for hours
2. Keep a pillow under the knee all day for comfort
3. Sit in a chair most of the day with the knee bent
4. Keep the knee straight and avoid a pillow under it

Answer: D) Keep the knee straight and avoid a pillow under it. Prolonged knee or hip flexion causes contracture that prevents prosthesis fitting. The limb is kept extended and prone lying is encouraged as tolerated. Elevation may be allowed in the first 24 hours as ordered.
