Latest / Becker’s Healthcare Podcast / Hip Replacement Innovations, Robotics and Patient Safety with Dr. Daniel Sun
Transcript
- 0:00- Hi, everyone, and welcome to the Becker Spine
- 0:02- and Orthopedic podcast. I'm Haley Bosek, a staff
- 0:05- writer here at Becker Spine Review. Today, we're
- 0:07- pleased to be joined by Doctor. Daniel Sun,
- 0:09- an orthopedic surgeon at Tufts Medical Center and
- 0:11- assistant professor at Tufts University School of Medicine.
- 0:14- Doctor. Sun specializes in hip and knee arthritis
- 0:17- care, including interior hip replacement, knee and partial
- 0:20- knee replacement, robotic arm assisted surgery, and complex
- 0:23- revision cases such as periprosthetic
- 0:25- joint infections and fractures.
- 0:27- Hip replacement has changed dramatically over the last
- 0:30- two decades.
- 0:31- Patients who once spent days in the hospital
- 0:33- and weeks on a walker are now going
- 0:34- home in the same day, sometimes walking with
- 0:36- hour... Within hours of surgery.
- 0:38- Anesthesia has become more targeted, surgical techniques less
- 0:42- disruptive, and implants are being designed to last
- 0:44- longer than ever, which matters as patients come
- 0:46- to surgery younger and more active. But every
- 0:49- advance raises new questions. Are faster recoveries always
- 0:52- better? Which innovations are truly improving outcomes? And
- 0:55- what you're mostly marketing? And as payers push
- 0:57- care into outpatient settings, how do surgeons make
- 1:00- sure speed doesn't come at the expense of
- 1:01- safety?
- 1:02- Today, we'll dig into what's really changed in
- 1:04- the hip replacement, what the evidence says, and
- 1:06- where doctor Sun thinks the field is headed.
- 1:09- So let's just get started. You, said in
- 1:11- a recent article that due to ongoing innovations
- 1:13- in the field, hip surgeries are now not,
- 1:15- quote, your grandmother's hip replacement. From where you
- 1:18- stand, what's the single biggest change that makes
- 1:20- this true? And, what maybe has stayed stubbornly
- 1:23- the same?
- 1:24- Yeah. I think that our modern protocols for
- 1:27- getting patients up and moving have really been
- 1:29- the biggest difference maker. You know, something like
- 1:32- maybe twenty years ago, patients would expect to
- 1:34- stay at least three, four, five days in
- 1:37- the hospital
- 1:38- hip or knee replacement. And like you said,
- 1:40- these days,
- 1:41- sometimes they go home hours later after the
- 1:43- operation.
- 1:44- And I think that's been a real game
- 1:45- changer for us as physicians
- 1:48- and also for patients, you know, to get
- 1:50- them back to comfort in their home safely,
- 1:52- is, I think, huge for their recovery. What
- 1:55- stays definitely the same, I think,
- 1:57- is, you know, the biggest thing that we've
- 1:59- had a hard time putting a dent into
- 2:01- is the risk of infection after a joint
- 2:03- replacement.
- 2:04- We've tried a lot of different things. The
- 2:05- rate of people who get that complication have
- 2:07- stayed relatively the same,
- 2:09- despite a lot of the different things that
- 2:10- we've tried. So that's a big topic for
- 2:12- us.
- 2:13- Absolutely. And when we're sort of thinking of
- 2:15- those innovations such as interior approaches, robotics, and
- 2:18- new implant material, you know, you're seeing all
- 2:20- this hype every day. Which do you think
- 2:22- has made the most measurable difference in outcomes
- 2:25- and maybe what gets a little more credit
- 2:26- than data supports?
- 2:29- I think that the biggest thing that's made
- 2:31- the biggest difference for patients actually has been
- 2:33- the piece of plastic that we're currently using.
- 2:37- It's referred to as highly pro... Polyethylene,
- 2:40- and first got popularized in kind of the
- 2:42- late nineties, early two thousands.
- 2:45- And it's been a real game changer because
- 2:46- the wear through the plastic used to cause,
- 2:49- a lot of bone resorption and bone complications.
- 2:51- And now that we've basically eradicated that problem,
- 2:55- patients with replacements are lasting much longer for
- 2:57- them.
- 2:58- And that's been a huge win and basically
- 2:59- taking out one major complication
- 3:01- from, you know, the the profile of things
- 3:03- that we're having to deal with.
- 3:05- I think maybe something that gets a little
- 3:06- bit more credit than it deserves might be
- 3:09- robotics right now, which is, kind of a
- 3:11- hot topic that's,
- 3:13- up for debate in our field. But, you
- 3:15- know, obviously,
- 3:16- lots of people hear robot. They're very excited
- 3:19- about it. They think that, you know, it's
- 3:20- gonna be this amazing technology that makes things
- 3:23- perfect and pain free.
- 3:25- And the reality is that all the robots
- 3:27- have helped to advance a lot of stuff
- 3:29- in our field. We're still not sure, I
- 3:31- guess, what the specific targets are for that
- 3:33- and how much is really gonna impact the
- 3:34- patient. Thinking kind of what you said about
- 3:36- the material that you're using in specific implants,
- 3:39- I've heard this more and more, and I'm
- 3:40- sort of curious your take, like
- 3:42- how much has observation of bone health been
- 3:45- important in your approach to surgery in the
- 3:47- last couple of years? Was it something you're
- 3:49- thinking about going forward and is it something
- 3:51- you're still watching to see if data comes
- 3:53- back and just in general, how much does
- 3:55- bone health affect, you know, your surgical outcomes?
- 3:58- Yeah. Definitely. I think bone health plays a
- 4:00- big, has a big impact on patients' recovery
- 4:02- afterwards. Definitely, you know, when we put the
- 4:04- metal in, we put it in quite tightly.
- 4:06- So in patients who have poor bone health
- 4:08- and bone quality,
- 4:09- the risk of, for example, fracture during the
- 4:11- operation is a bit higher. So it's something
- 4:14- something that we counsel patients on pretty extensively,
- 4:16- preoperatively.
- 4:18- You know, for the most part, bone remodeling
- 4:20- and improvements in bone health can be kind
- 4:22- of slow for patients. And, obviously, most people
- 4:24- who come to us hoping for a surgery
- 4:26- are not looking to have a surgery,
- 4:28- years down the line. So most of the
- 4:30- time, it just comes into the form of
- 4:32- patient counseling.
- 4:33- Sometimes we can use adjuncts during the surgery
- 4:35- like bone cement to help fix the metal
- 4:37- better into their bones and kind of give
- 4:39- the bone a little bit more sense. Those
- 4:41- quietly become one of the biggest drivers of
- 4:43- a better outcomes.
- 4:44- How has the way you and your anesthesia
- 4:46- colleagues manage patients changed, and what difference does
- 4:49- it make overall for patient safety in your
- 4:51- practice?
- 4:53- I think that, you know, the biggest thing
- 4:56- has been that we collaborate a lot with
- 4:57- the anesthesiologists.
- 4:59- At our hospital, we have a meeting every
- 5:01- month just to make sure we're all remaining
- 5:02- on the same page. This includes physical therapy,
- 5:05- nursing, just everyone in the perioperative space.
- 5:08- And, you know, with things like shorter acting,
- 5:11- spinal anesthetics,
- 5:12- nerve blocks around the anesthesia, and everyone agreeing
- 5:16- on, you know, preoperative pain medication protocols, postoperative
- 5:19- pain medication. Yeah. Absolutely. It's like that flow
- 5:22- between both pain management, anesthesia,
- 5:24- as long as the surgeon seems
- 5:26- like really critical to overall patient outcomes,
- 5:29- that sort of seems,
- 5:31- what's most important.
- 5:33- I also wanted to ask same day hip
- 5:35- replacement is becoming routine and CMS has pushed
- 5:38- more joint procedures into an outpatient and ASC
- 5:40- setting. And I'm curious from your perspective, is
- 5:43- faster recovery always better recovery and how do
- 5:45- you interpret that in your own practice?
- 5:49- Sure. So I think, you know, it's important
- 5:50- to distinguish between
- 5:52- faster discharge and faster recovery. So CMS is
- 5:55- definitely pushing for faster discharges.
- 5:58- Whether that's necessarily associated with faster recovery or
- 6:01- not, you know, I think he's a little
- 6:02- bit patient dependent.
- 6:04- You know, of course, most of the people
- 6:06- who are being done as outpatient joints are
- 6:08- naturally going to recover a bit faster, so
- 6:10- I think that correlation is always going to
- 6:12- be there.
- 6:13- But I think that, you know, for the
- 6:14- patients that are qualified to be outpatient,
- 6:18- outpatient has been great for them. You know,
- 6:20- I think most patients do recover better in
- 6:22- the comfort of their own home. Yeah. Totally.
- 6:25- And that... Sort of thinking about that, a
- 6:26- lot of what I'm hearing is also, like,
- 6:28- candidate decision is really important.
- 6:30- And I'm curious how you decide who's a
- 6:32- good candidate for maybe same day discharge and
- 6:34- maybe who isn't. And has the patient patient
- 6:37- population for outpatient joint expanded maybe too fast,
- 6:40- not fast enough, or is it, like, really
- 6:42- just dependent on making sure you're just sending
- 6:44- the right person for the same day procedure?
- 6:47- Yeah. I think for for myself, somebody who's
- 6:51- good for outpatient surgery is somebody who's healthy
- 6:53- enough to tolerate the surgery.
- 6:55- Of course, number one, meaning that they don't
- 6:57- have any significant thing, for example, like cardiopulmonary
- 7:00- comorbidities
- 7:01- that really need a specialized anesthetic team.
- 7:04- It's somebody who has good support at home,
- 7:06- and that doesn't mean that they have to
- 7:07- have twenty four hour support. They have to
- 7:09- have, you know, someone readily available to help
- 7:12- them with tasks or come over in case
- 7:13- they're in some sort of,
- 7:15- you know, some sort of conundrum.
- 7:17- As far as has outpatient surgery expanded too
- 7:19- fast,
- 7:21- I think, you know, obviously, CMS is really
- 7:23- pushing things forward. And I think they're pushing
- 7:25- the pace at this point faster than the
- 7:27- surgeons are. For example, this year, CMS decided
- 7:30- that revision hip and revision knee could be
- 7:32- outpatient procedures,
- 7:34- which in my opinion is a little fast.
- 7:37- Of course, CMS wants to cut down costs.
- 7:40- But revision
- 7:41- hip and knee is, you know, there's a
- 7:43- wide variety there,
- 7:45- and a lot of complexity.
- 7:46- And I think pushing it towards the outpatient
- 7:49- coding system,
- 7:50- is almost encouraging surgeons to kind of take
- 7:52- on a little bit more risk.
- 7:55- Yeah. Kind of going deeper into that. I'm
- 7:56- curious. It's it's on the top of my
- 7:58- mind with bundled payment models like CMS and
- 8:00- team programs putting more financial pressure on episode
- 8:03- costs, sort of like what we were talking
- 8:05- about.
- 8:06- How do you balance the system rewarding both
- 8:08- speed and lower spending with protected patient safety?
- 8:11- You know, CMS kinda wants to see both
- 8:13- surgeons and physician wanna see patient safety, and
- 8:16- everybody likes the idea of speedy recovery,
- 8:20- but with less spending. So what do you
- 8:22- think in your practice? How do you balance
- 8:23- those?
- 8:25- Yeah. I think when we're thinking of things
- 8:27- like teams and bundled payment models and, you
- 8:29- know, surgical episode costs losers,
- 8:33- it's important to recognize that patient safety and
- 8:35- financial loss go hand in hand. Right? If
- 8:38- a patient is, not safely taken care of
- 8:40- and they come back to the hospital, well,
- 8:42- that's a huge financial hit for you in
- 8:44- a bundled payment system.
- 8:46- Whereas, you know, you just maybe spent a
- 8:48- little bit more on patient safety. Sure. Your
- 8:50- margin might be a little bit thinner. But
- 8:52- in the end, everybody kind of wins. So
- 8:54- I think those things do kind of go
- 8:56- hand in hand. Obviously, like you said, everyone's
- 8:58- trying to push the envelope as far as
- 9:00- where's the fine line between speed and safety.
- 9:03- But I think as long as the hospital
- 9:05- systems are, you know, conscientious and have meetings
- 9:08- to make sure things are appropriately taken care
- 9:10- of, which I think most hospitals out there
- 9:12- are. Yeah. Yeah. And that's always the dreaded
- 9:14- thing that I'm hearing from physicians to surgeons.
- 9:16- Like, no matter what you do, whatever you
- 9:18- spend, you just don't want readmission. Right? Like,
- 9:20- that's the main goal.
- 9:22- Yes. And kind of towards that too, patient
- 9:24- education has been a huge,
- 9:26- huge tool as far as decreasing
- 9:29- e... ER admissions,
- 9:30- you know, readmissions to the hospital. So I
- 9:32- think,
- 9:33- patient education has really expanded too, as we
- 9:36- lead up into the surgery. Yeah. And I
- 9:38- don't think you can talk about orthopedics without
- 9:40- talking about that looming topic of an ever
- 9:42- aging population.
- 9:44- And, patients are coming to hip replacements younger
- 9:46- and more active, and how many expect them
- 9:49- to see a new joint last than the
- 9:51- rest of their life. So I'm sort of
- 9:53- curious about that. How close are we to
- 9:55- a hip replacement that truly lacked a lifetime?
- 9:59- Yeah. So, you know, depending on what age
- 10:01- they are, I think, for some people that's
- 10:03- already a realized reality, especially with the newer
- 10:05- plastic like we talked about before.
- 10:08- You know, it's been on market for, you
- 10:10- know, close to thirty years now,
- 10:12- and the plastic wear properties have been looking
- 10:15- really, really good. And, typically, the plastic would
- 10:17- be the main limiting step as far as,
- 10:20- you know, what people would consider to be,
- 10:22- needing a piece of the hip or knee
- 10:24- replacement changed, if at all. And so with
- 10:27- the plastic lasting, you know, really, really strong,
- 10:29- even thirty years out, we're not even sure
- 10:32- how long it is gonna look good for
- 10:33- because it hasn't even been on market for
- 10:35- that long yet.
- 10:36- So I think we're getting, you know, closer
- 10:38- all the time. There's been improvements in the
- 10:41- plastic and the implants that we use. Obviously,
- 10:43- technology,
- 10:45- robotics or other types of enabling technology has
- 10:48- also been huge as far as improving patient,
- 10:51- implant longevity.
- 10:52- Yeah. I'm also curious where do revision surgery
- 10:56- and joint infections... Like, you treat all of
- 10:58- these... Like, while we're on the topic of
- 11:00- that, what do these failed cases teach you
- 11:02- about maybe what we haven't solved in,
- 11:06- hip repair in the first place when you
- 11:08- when you go back in those revision surgeries?
- 11:10- What's the most common thing you're seeing when
- 11:12- you're going in?
- 11:14- Yeah. So I think, you know, some of
- 11:15- the top reasons why people need their hips
- 11:17- and knees are done. Number one is infection
- 11:19- like we talked about. We've tried a lot
- 11:20- of different things. Unfortunately, haven't been able to
- 11:22- make a huge dent in this, pre catastrophic
- 11:25- problem for patients.
- 11:27- You know, mechanical instability or fractures are also
- 11:30- leading causes for why people need all of
- 11:32- that stuff redone.
- 11:34- And, you know, ultimately,
- 11:37- sometimes I think just, no matter what you
- 11:39- do, know, unfortunate complications do happen, but it's
- 11:42- important.
- 11:43- And I think everyone across our country has
- 11:45- been doing a really good job of this
- 11:47- to optimize patients as much as possible, meaning
- 11:50- that, you know, we don't just look at
- 11:52- a patient with arthritis and sign them up
- 11:53- for surgery the next day anymore.
- 11:55- Most hip and knee surgeons out there are
- 11:57- making sure that everything that can be optimized
- 11:59- is optimized,
- 12:01- so that we can decrease the risk of
- 12:02- all these complications.
- 12:04- Yeah. We sort of talked earlier about the
- 12:05- idea of, you know, robotics and where they
- 12:07- stand with all these different innovations and what
- 12:08- you're looking at. And I'm curious with robotics
- 12:10- and navigation and AI driven planning and wearable
- 12:13- recovery tracking and personal implants, entering joint replacements.
- 12:16- There's so much exciting stuff, but I'm curious,
- 12:19- like, when you see it with people, I
- 12:21- keep reading AI, but I don't really know
- 12:23- what, you know, procedure, what is the hype,
- 12:25- what is actually worth it. This is what
- 12:27- people are sort of balancing when it comes
- 12:29- to the headlines. And I'm curious when you
- 12:32- weave through the curiosity,
- 12:34- what do you think ten years from now
- 12:36- will stick? What will help replacement look like?
- 12:38- What will it be? What do you hope
- 12:40- and, you'll be seeing, you know, in ten
- 12:42- years from now?
- 12:43- Sure.
- 12:45- Well, I think that,
- 12:46- you know, the the surgical approaches that we're
- 12:49- using now, I think, will kind of always
- 12:51- be around. You know, there's a variety approach...
- 12:54- Of approaches that people use out there.
- 12:56- You know, and experienced hands, they're all doing
- 12:58- a great job for the patients. So I
- 13:00- don't see any,
- 13:02- fewer surgical approaches being done, you know, ten
- 13:05- years from now. I think,
- 13:07- AI is here to stay. So I think
- 13:08- in ten years, AI is certainly gonna be
- 13:10- contributing
- 13:11- a lot to how we're putting in implants,
- 13:14- you know, whether that's implant positioning,
- 13:17- or how we think that certain implants are
- 13:19- going to affect patients' postoperative,
- 13:22- outcome and satisfaction scores.
- 13:24- So I think AI is definitely here to
- 13:26- stay. I think robotics and navigation
- 13:28- will continue to play a role. Just as
- 13:30- the technology gets better and better, I think
- 13:32- we're gonna be able to see, really where
- 13:34- they shine as far as what patients are
- 13:36- getting out of them.
- 13:37- And then as far as wearable technology, I
- 13:39- think, you know, smart implants are already on
- 13:42- the market.
- 13:43- And I think that some patients are really
- 13:45- enjoying that. And I know some companies have
- 13:47- found,
- 13:48- some really cool uses for their wearable technologies
- 13:51- and smart implants.
- 13:52- And I think as long as that continues
- 13:55- to get better as well, I don't... Can't
- 13:57- see how that and AI is going to
- 13:59- probably become a bigger facet of joint replacement
- 14:01- in the future. Totally. Yeah. Last question I
- 14:03- have here. What's one thing about hip replacement
- 14:05- that you'd like patients and referring physicians,
- 14:07- to leave this conversation with?
- 14:10- I think it would be that,
- 14:12- you know, although hip replacement is one of
- 14:14- the most common procedures we do, and the
- 14:16- vast majority of patients love their hip replacement
- 14:18- and get through the surgical episodes without a
- 14:20- hitch, it is not a minor procedure. I
- 14:23- think sometimes patients come in asking for hip
- 14:25- replacement or other referring physicians tell patients to
- 14:29- get a hip replacement,
- 14:30- almost treating it like a teeth cleaning when
- 14:32- it's actually a pretty major procedure with some
- 14:35- real complications
- 14:36- that are, potentials. And so, you know, although,
- 14:39- seems like everybody knows someone who's had a
- 14:41- hip replacement, you know, just keeping in the
- 14:43- back of their mind that it is still
- 14:44- a major operation.
- 14:46- Well, Doctor. Sun, thank you so much for
- 14:48- the conversation. It's really great to have people
- 14:50- with insights like you to help us wade
- 14:52- through all the interesting innovations.
- 14:55- Thank you so much for walking us through
- 14:57- how far hip replacement has come and for
- 14:59- being candid about the questions the field still
- 15:00- needs to answer. That's all for today's episode
- 15:03- of the Becker Spine and Orthopedic Podcast. A
- 15:05- big thank you again to Doctor. Danielson for
- 15:07- joining us and sharing his insight.
- 15:09- Thanks for listening, and we'll see you next
- 15:10- time.
