A 56-year-old male with diabetes presents with a gangrenous foot. After evaluation, it is determined that amputation is necessary. What is the most likely underlying cause of his condition?

A patient is recovering from a transtibial amputation and is in the early postsurgical phase of rehabilitation. The physical therapist assistant (PTA) has been asked to help with early rehabilitation activities. What should the PTA focus on during this phase?

The following scenario has five questions that are related. Answer each question by indicating the Question # and your choice. For example: Question #1: F Question #2: E Scenario:You are working with a 56-year-old patient who has undergone a transtibial amputation (TTA). The patient is in the early stages of rehabilitation and you are assessing their range of motion (ROM) for optimal prosthetic use. The goal is to ensure the patient achieves full knee extension and hip extension to support proper gait mechanics and prosthesis fitting. Question 1: What is the primary reason for ensuring full knee extension in a patient with a transtibial amputation (TTA)? A) To improve balance and reduce fall risk B) To prevent knee flexion contractures and optimize prosthetic function C) To enhance muscle strength in the residual limb D) To decrease the risk of phantom limb pain Question 2: What is the key benefit of maintaining full hip extension for a transtibial amputation (TTA) patient? A) It facilitates smoother prosthetic gait and proper alignment during ambulation. B) It decreases the risk of skin breakdown around the prosthetic socket. C) It reduces swelling in the residual limb. D) It improves the patient’s ability to bear weight on the residual limb. Question 3: Which of the following is most likely to occur if the patient with TTA does not achieve full knee extension during rehabilitation? A) Improved prosthetic fit B) Difficulty in maintaining balance during walking C) Increased muscle mass in the residual limb D) Enhanced gait speed Question 4: As a PTA, what would be an appropriate intervention to address limited knee extension in a TTA patient? A) Encourage extended periods of sitting with knee flexion to stretch the joint. B) Begin passive range of motion (PROM) exercises focused on knee extension. C) Apply resistance exercises for the quadriceps and hamstrings. D) Use a prosthesis immediately to encourage knee extension. Question 5: If a TTA patient is struggling to achieve full hip extension, which of the following techniques would most likely help improve their ROM? A) Prone positioning with hip extension stretches to target the hip flexors. B) Sitting in a chair with the knee flexed to promote hip extension. C) Avoiding all weight-bearing activities to prevent hip strain. D) Applying cold therapy to reduce swelling in the hip joint.  

Which of the following positioning guidelines should be followed to prevent contractures in patients with transtibial amputation (TTA)? A. Encourage prolonged hip and knee flexion positioning   B. Maintain knee extension while seated   C. Elevate the limb on pillows in bed (envision one of these legs as the amputated limb)   D. Place a towel under the knee for comfort
