How will calf implant surgery affect my ability to practice sports involving intense leg movements?

Depends/likely: The calf implants for cosmetic enhancement of your leg will have some impact on your calf muscle performance. Okay to ask/talk to your cosmetic surgeon about this issue. Like a breast implant, the calf implants are usually under the muscle, sometimes they can be above the muscle. Take a friend with you to help with the risk/benefit visit. Good luck.
