You may be the victim of the internet, both with it's over abundance of misinformation, simultaneous with it's ability to give detailed information that can't be adequately processed by the general public. There is nothing in the plastic surgery literature about 'double plication' of the rectus fascia with regards to it's application to athletes. That's because our goal is to perform individual tasks within a procedure, e.g. rectus plication during a tummy tuck, that is maximally effective and durable in every patient. How this is accomplished is a surgeon preference, based on training and experience. In my hands, the rectus fascia is plicated with individual stitches to near maximum tension. Then a second stitch is run from top to bottom to smooth out the contour along the entire abdominal wall; this is done for cosmetic purposes, not increased durability. In fact, we know from the general surgery literature that too many sutures can lead to a break down of a repair due to diminished blood flow to the area being repaired. So, all is not what it seems in medicine and surgery, especially when complex information is being given to a lay person. My recommendation is to visit a few ABPS certified/ASAPS member surgeons that have been doing tummy tucks for decades. Best of luck!
