What is the recommended position for preventing flexion contracture of the knee after a below-knee amputation (BKA)?

The recommended position for preventing flexion contracture of the knee after a below-knee amputation is to constantly straighten the knee while standing. This positioning is critical because it helps maintain the proper alignment and extension of the knee joint, which can otherwise become stiff and develop a contracture if left in a flexed position for prolonged periods.

Flexion contractures can significantly restrict mobility and function, making it essential to encourage knee extension to promote flexibility and prevent complications. Keeping the knee straight allows for better alignment of the leg and can facilitate the rehabilitation process, including walking and adapting to the use of prosthetics.

While there are other considerations for limb positioning, such as avoiding prolonged sitting or lying with a bent knee, these options do not provide the necessary support needed to prevent the complication in question. Maintaining the knee in a straighter position, especially during weight-bearing activities, is beneficial for long-term recovery and functionality after a below-knee amputation.
