Hip surgery: anyone know anything about femoral head resurfacing?

[Flaxbee]

Anyone have such surgery, or know someone who did, or know anything about it?

Not asking for medical advice! Just wondering what the experience was like.... my dad has enormous amounts of hip pain and is thinking about it.
