What is the optimal socket flexion angle for a patient with a 5-degree contracture?

The optimal socket flexion angle for a patient with a 5-degree contracture is 5 degrees. This alignment considers the existing contracture in the patient's limb, allowing for a more functional and comfortable fit of the prosthesis. Maintaining the socket flexion angle at 5 degrees aligns the prosthetic socket with the patient's actual anatomical position, optimizing comfort, stability, and function during ambulation.

When the socket is flexed to match the contracture, it enables the user to walk with a more natural gait without undue stress on their hip and knee joints, which can happen if the socket angle is too extended. A flexion angle equal to the degree of the contracture - in this case, 5 degrees - accommodates the patient's anatomical limitations while preventing further complications, such as skin irritation or pressure sores, which can arise from misalignment.

On the other hand, zero degrees may not account for the existing contracture, potentially leading to discomfort and difficulty in movement. Similarly, choosing a higher flexion angle, such as 10 or 15 degrees, could result in an unnatural gait and additional strain on the patient's joints, increasing the risk of injury or discomfort. Therefore, matching the socket flexion angle directly to the degree of the contracture
