How is muscle/tethered scar released after explant? (photos)

I had my implants removed and had a capsulectomy, and a capsulotomy done on the right side (I got CC twice). Now the bottom of my breast crease seems to have contracted upwards and have lost some volume on the bottom outside of my breast. It also seems that my tissue is stuck to my muscle because when I push my breast to have cleavage, the center most part doesn't move. Maybe considering fat grafting but am afraid of cysts.
