My initial break was complex enough that they needed to incisions. One of them is kind of the front of my groin/pelvis, and that site got infected and required some intervention to heal. It healed ugly, with lots of scarring.
NORMALLY, though, for a replacement that's exactly where they'd go in ("anterior approach"). My surgeon wisely demurred and opted for the older posterior entry, around the back of my left thigh and buttock, but that means a slightly more complex recovery with more restrictions for longer. Basically, if I bend too much a given way, or twist, or put too much load on it, I risk dislocating the implant, which would be VERY VERY BAD. Even so, the scar tissue & such presented too much of a risk of healing issues, infection, etc, so it's a trade we were okay with.
You, though, will probably GET the anterior approach, which doesn't have this risk.
