Calf implants, made of FDA-approved solid silicone, enhance the proportion and definition of the lower legs as well as correct muscle imbalance caused by physical defects. Patients lie on their stomach as the surgeon makes an incision in the natural crease located behind each knee. A pocket is created between the muscle and the fascia (tissue that covers the muscle) for the implant to be placed below the muscle (submuscular) or above the muscle (subfascial). The implants can also be placed on the medial (upper inside) or lateral (outside) of the leg for a larger appearance.
