Calf Augmentation with Silicone Implants. Our 31 year-old male patient underwent a calf augmentation procedure with silicone implants to improve the outer look of his legs. Calf augmentations with implants is a plastic surgery procedure to increase the size and shape of the calfs to improve their look. Patients seek calf implants to tone and add definition to the lower legs, in most cases, if it cannot be achieved with routine exercise, or to correct an imbalance of the muscular structure as a result of a physical or birth defect. To further increase the size of his calves and contour Dr. Tehrani also added some of the patient’s own fat as a finishing touch. The patient’s final result was natural looking muscular and toned calves.
