Which is a major downside of the supracondylar prosthetic design?

The major downside of the supracondylar prosthetic design being a higher trimline is particularly significant due to its impact on the user's comfort and levels of mobility. Higher trimlines of the supracondylar design can restrict the range of motion during walking, running, or engaging in other activities, making it more difficult for the user to achieve a natural gait. This design primarily aims to provide some degree of stability around the knee joint, but the trade-off is often a limit in the flexibility that can be experienced by the user.

Conversely, certain advantages offered by lower trimlines include increased ease of movement and better adaptation to varied terrains or walking conditions. While stability is a crucial aspect of any prosthetic design, in the case of supracondylar options, the higher trimline can lead to challenges in terms of comfort and mobility, making it a disadvantage in the overall assessment of functional performance. Therefore, the higher trimline indeed stands out as a notable drawback in this specific prosthetic design.
