When I first started out in the gym at Main Event (Sting and Luger's gym) there was a surgeon there that did almost everyone in the gym for a discount price. They all looked nice but had the tell-tale scar behind the knee that stood out. One guy went to another surgeon and his implants must have been done wrong because on the outside of the calves he had an oval red shape there. Like a tiny surf board bulging under the skin. The skin was always red and when he walked it looked really weird. The first surgeon offered to correct it for him and he refused. But a few years later he had them removed by someone else because he was having trouble walking and afterwards he ended up with nerve damage in the area and was confined to a wheel chair. Wasn't even 30 years old either.
