Calf augmentation, via implants, adds definition and bulk to the calf muscles while improving the look of the lower legs and correcting muscle imbalance from physical defects. An incision in the natural crease behind the knee creates a pocket large enough to place the calf implant on either the outside of the leg or the upper inside of the leg. Calf implants, available in silicone gel and solid silicone, can be placed subfascially (beneath the fascia) or submuscularly (within the muscle). Subfascial placement is less invasive and has a faster and less painful recovery time. Submuscular placement is more difficult because the surgeon must dissect deeper into the muscle tissue.
