A surgeon argues that robots and AI in hip replacement are marketing hype that add nothing clinically. Robots can only position a cup; the surgeon does the rest. Real improvement comes from better implant design, specifically dedicated right-left stem designs, not from technology.

The robots are being used as marketing tools. They're marketing, they're bling, they're sales tricks. A robot can't even examine a patient, let alone put them on the table, position them, adjust things and know how to position them for surgery. They can't prep and drape, they can't make the incision, they can't do the dissection. All they do is bring this thing in to tap the cup into place and say, oh, that's accurate. And then out it goes, and then someone else, people have got to sew it up. And get the patient off the table, look after them post-op. So if you look at the robot's contribution to that whole event, it is minuscule. It's trivial, but it's been pumped up as a marketing trick to influence referral patterns. And hospitals are using it to say, we've got the best surgeons because they're robotic. It is total BS. And as a surgeon, I feel really strongly about it. That's called acumen. It's judgment, and robots don't have it. And AI doesn't have acumen and judgment either. I mean, it's brilliant, don't get me wrong, AI is brilliant, but I can't see AI ever— it'll be just like the robot. AI can tell the robot how to plan the surgery, how to put it in there, and it still won't be any good if the implant isn't improved. So AI is not the answer, robot's not the answer. Go back to the implant.
