A rotationplasty leg prosthesis cover is a specialized covering designed to aesthetically and functionally enhance the appearance of a prosthetic limb used by individuals who have undergone rotationplasty. Rotationplasty is a surgical procedure typically performed for bone cancer patients, where a portion of the limb is removed and the remaining part is rotated and reattached. This unique procedure often results in the foot being positioned where the knee would typically be, allowing the ankle to function as a knee joint.
