Prosthetic augments to improve muscle mechanics are disclosed herein. A prosthetic augment of the present disclosure includes an augment member configured to engage a bone, the augment member having a first face adapted for contacting the bone; and a second face adapted for contacting an underside of a muscle, wherein at least a portion of the second face includes a bulbous surface adapted to alter a wrapping angle of the muscle around the bone, wherein a first thickness is defined between the first face and the second face at a first position on the augment member, wherein a second thickness is defined between the first face and the bulbous surface of the second face, and wherein the first thickness and the second thickness are not equivalent so as to result in the augment member having a non-uniform thickness.
