Every plastic surgeon has had the same conversation a thousand times across a desk. The patient is in for a consultation about a planned operation. The operation is well-understood, the indication is clear, the plan is in place, and then the patient asks, quietly, almost as an afterthought, the question that turns out to matter most. What is the scar going to look like.
The honest answer, for years, has been a list of variables that the surgeon controls only partially, layered on top of a list of variables, like genetics and skin type, that the surgeon does not control at all. That answer has been mostly true. It has also been incomplete, because one of the variables sitting right at the surgeon’s hand has been almost entirely absent from the conversation.
The variable is the blade itself. A 114-patient clinical study I served as a principal investigator on, picked up by MPO Magazine in early 2025 under the headline “Significant Reduction in Hypertrophic Scarring Seen With Planatome’s Surgical Blades,” put a hard number on what I had been suspecting in my own practice for years. A cleaner cut produces a quieter scar.
This is the longer surgeon-to-surgeon version of that finding, and what it means for the consultation that starts with “what is my scar going to look like.”
The Study, in One Paragraph
I co-led the 114-patient clinical study evaluating the Planatome surgical blade alongside Michael Sanchez, PhD. The Planatome blade is manufactured with a polishing process that produces a smoother, sharper cutting edge than a standard surgical blade. The study followed patients through standardized incisions and assessed scar quality at multiple time points. The headline finding was a measurable reduction in hypertrophic scarring in the Planatome arm. The trade industry coverage called the reduction significant. I will let other investigators replicate the finding on other populations and in other operations before I make stronger claims, but the result is internally consistent and clinically meaningful.
Why a Cleaner Cut Produces a Quieter Scar
The wound healing cascade begins the moment the blade enters the skin. The depth of the cellular insult at the incision edge is one of the largest single inputs into the inflammatory response that follows. A standard surgical blade, even a brand-new one straight out of the package, has microscopic irregularities along the cutting edge that are functionally invisible to the surgeon at the time. Under a high-magnification image, those irregularities tear the tissue along the incision rather than cleanly transecting it. The cells along the wound edge respond not to the surgeon’s intent but to the cellular environment they are actually in.
A polished, sharper edge produces a different cellular environment. The cells along the incision are cleanly transected rather than crushed. The local inflammatory cascade is quieter. The fibroblast recruitment, the collagen deposition, and the final remodeling that produces the mature scar all start from a different baseline. In the patient who would have formed a flat, fine scar under almost any technique, the difference is invisible because the result was always going to be good. In the patient who would have formed a raised, thickened, hypertrophic scar under any technique, the quieter starting point shifts the curve.
This is the kind of finding that, in retrospect, looks obvious. A sharper knife should produce a cleaner cut and a quieter cellular environment. The reason we needed a study to confirm it is that “obvious” is the most dangerous word in medicine, and the difference between intuition and data is the difference between marketing and a recommendation a surgeon can stand behind.
What the Study Did Not Claim
The study did not claim that blade quality is the only variable in scar formation. It did not claim that a sharper blade will turn a keloid-prone patient into a fine-line healer. It did not claim that the blade matters more than the closure technique, the incision design, the tension on the wound, or the genetics the patient brought with her.
It did claim that, holding the other variables steady, the edge of the blade itself moves the needle. That is a meaningful claim. It is not the only claim.
What I Tell Patients at the Consult
Scar quality is decided across six decisions and one variable I do not control.
The variable I do not control is the patient. Genetics, skin type, anatomic risk, and personal scar history all enter the room with her.
The six decisions are mine. The incision location. The incision orientation. The incision length. The blade. The closure plan, including the layers and the suture choice. The post-operative scar care plan, including silicone, compression, sun protection, and any post-op laser or microneedling on indication.
A sharper blade is the easiest of those six decisions to make. The hardest is honest expectation setting with the patient about what her skin will actually do, regardless of any decision I make.
Where This Lands in Practice
I use the Planatome blade in operations where scar quality is most consequential, including breast augmentation, tummy tuck, mommy makeover, facelift, and any operation on a patient at elevated risk for hypertrophic or keloid scarring.
I also use the study’s existence at the consultation. The patient who wants to know what can be done to give her the cleanest possible scar gets a real answer rather than a vague reassurance, and the answer includes a study I helped design rather than a generic platitude about being careful with the incision.
The trade industry coverage in MPO Magazine framed the result as significant. I would agree. I would also frame it as one of several variables a surgeon can and should optimize for scar quality, and the variable that is easiest to control. The reason it took a 114-patient study to put the finding on the record is that the field genuinely needed the data.
A Brief Word on What the Field Should Do Next
The Planatome study is one data point in a larger conversation about how blade geometry, blade manufacturing, and blade sharpness interact with the inflammatory cascade and the final scar. The questions worth answering next are predictable. Does the effect hold across all skin types and all anatomic locations. Does it hold for procedures that involve electrocautery for the deeper dissection but a cold blade for the initial skin incision. Does it interact with newer scar management modalities, like silicone alternatives, post-op fractional laser, and microneedling at the right interval.
Other investigators will answer those questions in time. The study I co-led is the floor for that work, not the ceiling.
How I Talk About the Whole Scar Equation
When a patient asks “what is my scar going to look like” at a consultation, the honest answer takes ten minutes. It is the most useful ten minutes of the consultation, because the scar is the part of the operation she will see in the mirror for the rest of her life. The plan we make about the scar is the plan we make about her relationship to the result of the operation.
The blade is one part of that ten minutes. The study makes it possible to discuss the blade as a variable backed by real data rather than as a vague reassurance about surgical care. The rest of the ten minutes is still about the patient, the operation, the closure, the post-op plan, and the contingency plan if the scar does not behave the way we hope.

If a planned operation is on your mind and the scar is part of what you are weighing, the first conversation is a consultation. The ten minutes about the scar will be the most useful ten minutes of the visit.
