Calf implants enhance the shape and size of the calf muscles by placing soft, solid silicone implants in pockets overlying the existing gastrocnemius muscles. The calf muscle is a two-headed muscle (one head on the upper inside of the leg and the other on the upper outside of the leg) on the back of the leg that attaches on each side of the femoral bone just above the knee and extends down the leg ending as the Achilles tendon at the heel.
These implants which may be one to each leg or two depending on the desired effect are placed through small incisions in the creases behind the knee. A person may desire to have only the inner head of the muscle enlarged, the outer head, or both. The result is that the existing musculature is made to appear larger and more defined.
