@Mojo333 In have both had the numbness or the feeling my quad was kicked by a horse this time around.
The previous surgery? Yes, absolutely. There around The LTHR incision and around the side to the trochanter felt like it had been kicked by a horse, or hit with a #10 sledge hammer. I'd have to look back in my timeline, but it was months before that sensation went away. It was several more months before I could sleep on my left side.
Right after surgery I had about a square-foot of area on my upper leg that was numb/ pins-and-needles kind of feeling. As the feeling of getting kicked subsided, the sensation of touch came back. Now, I have a two square inch area at the bottom and to the left of the scar they has no skin sensation. I can feel pressure, but not touch or temp. I almost got all of it back. I have a friend who had his first hip done before anterior approach was available. He has no feeling in his lower leg. The muscles work, but he can cut his foot and not know it. He can tell if his shin gets banged. But not hot or cold.
I was told that during anterior approach, the stress put on your quad is the equivalent of 10,000 leg extensions. So that is why you feel like you were punched. I'm essence, you were.
All things considered, it is still better than it was.
I do have a small patch of feeling loss on the RTHR. It is the same relative location as the other leg. It is probably 4 in sq. It just never felt like it had the same level of trauma as the other side.
Vastus Lateralis?
