Which of the following is true about knee disarticulation socket principles?

The correct choice asserts that subischial or 3/4 sockets are appropriate for knee disarticulation. This is due to the unique challenges and anatomical considerations associated with a knee disarticulation amputation.

In a knee disarticulation, the residual limb includes the femur but the knee joint has been removed. Therefore, the socket design must accommodate the residual anatomy while providing effective load distribution and stability. Subischial sockets leave a portion of the ischial tuberosity exposed, allowing for comfort and reducing pressure on sensitive areas. They also offer a lower profile, which can enhance the cosmetic appearance and functionality of the prosthetic limb. 3/4 sockets are also designed to provide adequate support while accommodating any specific anatomical needs of the individual.

The other options suggest certain limitations or specifics about the amputation that do not align with the reality of socket design. For instance, stating that anatomical suspension is the only option overlooks the fact that various suspension systems can be utilized effectively based on individual needs. Requiring above-knee support ignores the design flexibility available with knee disarticulation sockets. Lastly, the exclusivity to children disregards the fact that knee disarticulation can occur in individuals of any age,
