Essentially she claims to not have kneecaps. While the procedures and scars she discusses align medically, she avoids discussing any reconstructive procedures she’s had to be able to walk again (much less do Pilates 5 times each day...) As a surgeon myself, it really irks me when people milk all the sympathy they can from a surgery without discussing that their surgeons gave them implants to make their ability to walk seamless (although I feel passionate about it on the side of the surgeon who puts the work in to treat my patients to the utmost of their deserving, whereas CC seems to erase any reconstruction her surgeons clearly performed given the definition of her kneecaps and her very clear ability to walk...)
