Yes, I realize they are both invasive and yes, probably a marketing ploy. However, if you look it up, that’s what it is called. Basically, it’s cutting the quad muscles vs not cutting the quad muscles, from what I understand. My former co-worker had the quads cut, whereas I did not. Her recovery, from the same facility as mine, is very very different. From what I have known, with what they call minimally invasive is the incision is shorter, how they move the patella is different and what they cut is different. It is a newer technique but still invasive and painfuL. I know of the robotic assisted and yes, realize that is also invasive. There is no getting around knee replacement as non-invasive. It may be a marketing ploy, but trying to say it as to how it seems to be interpreted when talking to people, at least around here. It is as question that many of my former co-workers have asked as many of either our selves or our parents have gone through it. Did they cut the quads? Which surgery did you have?
