I was born with a clubfoot my calf in the one leg is extremely thin. How can I improve this?

Other than favorable genetics combined with rigorous consistent exercise, there is no other way to augment the calf muscles besides calf implants.  This applies to various acquired diseases and genetic/traumatic deformities as well.  Buyer beware - Fat transfer will NOT work, period!  Surgical prices vary by region, surgeon reputation, and surgical experience.  However, very few plastic surgeons specialize in this operation so you may have to travel a long distance to one that does. The implants are made of soft semi-solid silicone rubber and placed surgically through a small (3/4 inch) incision in a natural crease behind the knee. When the implants are properly sized and placed under the muscle fascia, they should blend in and look natural. There are too many critical nerves and blood vessels under the muscle to risk this technique. All surgery comes with post-operative pain and recovery.  For calf implants, the first two weeks after surgery is the most difficult time because walking is painful. Recovery usually progresses at a smooth steady pace from there until unlimited activity/sports/exercise is allowed at 6 weeks. Glad to help.
