In a patient with a right above-knee amputation and a long history of bilateral lower-extremity vascular insufficiency, which factor is MOST important to consider when establishing long-term goals for functional walking?

• A. Status of the wound at the amputation site.
• B. ROM of the right hip.
• C. Condition of the left lower extremity.
• D. Ability to maintain upright posture.

Answer: (C)

The most important factor is the condition of the left lower extremity because it serves as the primary weight-bearing and propulsion limb during walking with a right transfemoral prosthesis. Even with a functioning prosthetic knee and good residual limb healing, a healthy contralateral leg is essential for sustained ambulation. In bilateral vascular insufficiency, the left leg’s status—pain, claudication, ulcers, and overall perfusion—will largely determine how far, fast, and safely the patient can walk, how much endurance can be built, and what level of assistive device or support is needed. If the left leg is compromised, walking capacity will be limited regardless of the right-side prosthesis condition. Wound healing at the amputation site matters for prosthetic fitting and early rehabilitation, and right hip ROM can influence gait mechanics, but they do not set the ultimate long-term walking potential as strongly as the health of the remaining, contralateral limb. Upright posture is important for balance, yet without a healthy left leg to bear and propel the body, functional walking remains constrained.
