What is the ideal resting position for a transtibial amputation?

• A. Supine with hip flexion and knee extension
• B. Supine with hip neutral flexion and knee extension
• C. Sidelying with knee extended
• D. Standing with knee extended

Answer: (B)

The main idea is to prevent contractures in the joints near the amputation and keep the residual limb in a position that will allow comfortable, effective prosthetic fitting later. For a transtibial amputation, a hip flexion contracture is particularly problematic because it can make it hard to place the residual limb into full extension inside the prosthetic socket and can complicate gait. Keeping the knee in full extension preserves this joint’s range and helps ensure a proper socket fit. So the best resting position is lying on the back with the hip in a neutral position (not flexed or extended) and the knee extended. This reduces the risk of developing hip flexion contractures and knee flexion contractures while maintaining alignment for future prosthetic use. Lying on the side or standing during rest can encourage unwanted joint positions and is not ideal for preserving contracture-free alignment.
