Robotic Hip Replacement Surgery

Free consultation

Send your hip X-rays and find out whether replacement is the right operation for you

The review costs nothing and commits you to nothing. Send a standing pelvis X-ray of both hips, any hip CT or MRI you already have, a list of your current medicines, and a note of how far you can walk before the pain stops you. An orthopaedic surgeon reads the images and tells you whether a replacement is warranted yet, whether the robotic approach would change anything in your case, and what the operation would involve, before you spend money on flights.

What the robot does in theatre

Robotic hip replacement surgery is an ordinary total hip replacement in which a CT scan of your own pelvis and thigh bone is turned into a three dimensional plan before the operation, and a robotic arm then keeps the surgeon inside that plan while the socket is prepared and the implant is seated. The damaged joint surfaces come out. A metal shell goes into the socket of the pelvis, a liner of plastic or ceramic goes inside the shell, and a stem with a ball on top goes down the thigh bone. That part is the same operation surgeons have been doing for sixty years.

The arm does not cut, drill or place anything on its own.

Your surgeon makes the incision, moves the muscle, holds the tool and does the reaming, and the arm resists when the tool strays outside the planned boundary. Surgeons call that haptic guidance, which means the machine pushes back against your hand instead of taking over from it. The software also reports the angle and depth it is seeing as the work goes on, so a socket sitting two degrees off the plan is visible at the moment it happens instead of on the X-ray the next morning.

Clinics use the phrase loosely, so it helps to know what sits behind it. Two systems account for most robotic hip replacements worldwide. Stryker's MAKO platform, cleared in the United States for total hip replacement in 2015, plans the operation from a CT scan taken beforehand and then holds the surgeon's reamer inside that plan. Zimmer Biomet's ROSA Hip, cleared in 2021, was designed around the direct anterior approach and works from live X-ray images taken during the operation instead of a CT, reporting cup angle, leg length and offset as the surgeon goes. Private hospitals in Turkey advertising robotic hip replacement are usually running one of these two.

Plain computer navigation is a different and older thing. It shows the surgeon angles on a screen with no robotic arm holding the instrument, and it is not what the trials on robotic hip replacement are testing. Ask which of the three is in the theatre where your operation would happen.

From CT scan to closing the wound

Planning begins with a CT scan of the pelvis, the hip and the knee, taken days or weeks before surgery. Software builds a model of your bone from it and the surgeon sizes the implant on that model, choosing where the centre of the new joint sits, how much the leg lengthens, and how far the ball sits out from the pelvis, which surgeons call offset. Getting offset and leg length right is what decides whether you walk evenly afterwards and whether the muscles around the joint have the tension they need.

Fluoroscopy-based systems work differently. They skip the CT and build the plan from X-ray images taken in theatre, which takes one scan and its radiation dose out of the process, and everything after that runs much the same way.

Anaesthesia is worth asking about separately. Many hip replacements are now done under spinal anaesthesia with sedation rather than a general anaesthetic, which tends to mean less sickness afterwards and an easier first few hours, though the choice depends on your heart, your lungs and any blood thinning medicine you take.

Posterior or direct anterior

Two routes into the hip account for most replacements worldwide, and robotic systems work through either one. The posterior approach comes in from behind the hip and detaches a small group of muscles at the back, which are repaired at the end. The direct anterior approach comes in from the front, between muscles rather than through them, and needs no muscle detachment at all.

Patients who research this often arrive convinced the anterior route is simply better. The honest position is narrower than that. Anterior surgery tends to give a slightly faster first two or three weeks, with less early limping and fewer restrictions on sitting and bending. By three months the two groups are usually indistinguishable on function scores, and the anterior route carries its own specific problems, including numbness over the outer thigh from irritation of a small sensory nerve, and more difficulty in patients who are heavily built around the hip.

What matters more than the approach is which one your surgeon does several times a week. A surgeon who has done two thousand posterior hips will get a better result from a posterior hip than from a technique they adopted recently, and no robotic system compensates for that.

Am I a candidate?

Candidacy rests on the X-ray and on how much of your life the hip has taken, and both have to point the same way. The picture that supports surgery is a joint space that has narrowed to bone against bone, pain in the groin that wakes you at night, a walking distance that has shrunk to a few hundred metres, and difficulty with socks, shoes and stairs. Osteoarthritis is the commonest reason. Avascular necrosis, in which the ball loses its blood supply and collapses, hip dysplasia carried since childhood, rheumatoid arthritis and a badly healed fracture account for most of the rest.

Where the robotic version helps most

Difficult anatomy is where accurate planning earns its place. A shallow socket from childhood dysplasia, a hip that has already been operated on, a leg that is visibly shorter than the other, a very small or very large frame, and a previous fracture that has healed crookedly all make the standard landmarks unreliable, and a plan built from your own CT gives the surgeon numbers to work to instead. Patients whose two hips already differ in length gain the most. Leg length is the one measurement the robotic systems reduce consistently across the published trials, and it is the measurement patients notice.

Who should not have this operation abroad

Some people are turned down, and being told so plainly is more useful than being flown in and reassessed. An active infection anywhere in the body, including a dental abscess or an infected leg ulcer, rules out surgery until it is treated, because bacteria settle on new implants. Poorly controlled diabetes raises the wound infection risk enough that most surgeons want the blood sugar brought down first. A body mass index above roughly 40 raises infection and dislocation risk and many units will ask for weight loss before booking. Severe heart or lung disease that makes anaesthesia dangerous, a recent heart attack or stroke, and cancer under active treatment all need clearance from the treating specialist rather than an orthopaedic opinion alone.

Travelling adds two more. Anyone who cannot arrange a companion for the first fortnight, and anyone with no realistic access to a doctor at home for wound checks and blood tests, should think carefully before booking a hip replacement in another country, because the operation is only the first two hours of a process that runs for months.

Is robotic better than conventional surgery?

Four systematic reviews published between 2022 and 2025 give a consistent answer, and it is more measured than most clinic pages suggest. A 2025 meta-analysis in The Journal of Arthroplasty pooling 38 comparative studies and 10,055 patients found that robotic assistance placed significantly more sockets inside the accepted safe zone and restored the natural centre of the joint more closely, with a lower overall complication rate, while operating time was longer and patient reported scores such as the Harris Hip Score and the Forgotten Joint Score showed no difference at all between the two techniques.

A 2024 review in the Journal of Robotic Surgery narrowed the question to randomised trials only, eight of them covering 1,014 patients. Leg length discrepancy came out about 4 mm smaller with the robot. Major complications, revision rates and patient reported outcomes were no different, and the authors graded most of their pooled estimates as low certainty because the individual trials were small and inconsistent.

A 2023 meta-analysis in the Postgraduate Medical Journal covering 3,600 hips reached the same place and went further in its recommendation. Accuracy improved and limb length discrepancy fell, but with operating times longer, complication and revision rates unchanged and long term follow up still missing, its authors declined to recommend robotic assistance for routine hip replacement. A separate 2023 meta-analysis in The International Journal of Medical Robotics and Computer Assisted Surgery, covering 2,845 hips, found better socket angles, better stem alignment and fewer complications overall, but reported more dislocations in the robotic group, which is the one clearly unfavourable finding in this literature and deserves saying out loud.

So the fair summary is that the robot improves the numbers on the post-operative X-ray, reliably, and that those numbers have not yet been shown to change how your hip feels at one or two years. The theory behind it is sound, because implants placed badly do fail sooner, and the position the robot achieves is the position associated with longer survival. Proving that link takes ten to fifteen years of follow up on patients operated on with this generation of equipment, and that data does not exist yet. Anyone telling you robotic hip replacement is proven to last longer is ahead of the evidence.

Risks you should know before travelling

Hip replacement is one of the most reliable operations in surgery and it still carries real risk, which rises when the patient is going to be a long way from the operating team a fortnight later.

Two risks belong specifically to the robotic version. Pins are fixed into the bone to hold the tracking arrays, and the pin sites can very occasionally fracture or become infected. And every system depends on the registration step being accurate, so a plan matched slightly wrong to the real bone produces confident numbers on a screen that are quietly incorrect, which is a reason to care about how often the surgeon uses the system rather than whether the hospital owns one. Operating time with these platforms falls as a team gains experience on them, so how many robotic hips the surgeon does in a month is a fair question to put before you book.

Recovery week by week

Walking starts on the day of surgery in most units, with a frame or crutches and a physiotherapist beside you, and the first attempt is short. Standing and taking a few steps within hours is now routine, and it is one of the main reasons clot rates have fallen.

Days one to five

Pain is managed with a combination of tablets rather than one strong drug, and most patients describe the ache as heavy rather than sharp. Physiotherapy covers getting in and out of bed, walking on the flat, and climbing stairs one step at a time. Discharge from the ward comes when you can do those three things safely, which for most people falls between the third and the fifth day.

Weeks one to three

Crutches stay in use and the walking distance grows a little each day. Swelling in the thigh and down to the ankle is normal at this stage and worse in the evening. Stitches or clips come out around day twelve to fourteen, which is the appointment that decides when it is sensible to fly.

Weeks four to twelve

Most people move from crutches to a stick somewhere in the fourth to sixth week and then to nothing. Driving usually becomes possible between four and six weeks, once you can perform an emergency stop without hesitating, and desk work often restarts around the same point. Physical jobs involving ladders, lifting or long periods standing take three months or more.

Three months to a year

Swimming, cycling, golf and hill walking are all reasonable once the wound has healed and strength has returned, and most surgeons ask patients to avoid running and contact sport permanently to protect the bearing surfaces. The last of the stiffness and the muscle bulk around the hip continues to improve until roughly the one year mark. A hip that keeps aching at six months is worth investigating.

How long you stay and when you can fly

Packages published by Turkish hospitals and medical travel agencies commonly plan 10 to 14 days in the country for a single hip replacement, with 3 to 5 nights on the ward and the rest in a hotel nearby. Robotic packages sit at the longer end, because the planning scan adds a day before surgery. The pattern behind those numbers is straightforward. You arrive two or three days early for blood tests, a chest X-ray, heart tracing, the planning CT and the anaesthetic review. Surgery follows. Then you need to reach the point where the wound is dry, the stitches are out and a surgeon has looked at you before you leave.

Flying too early is the mistake that causes the most trouble. Sitting still in a pressurised cabin with a freshly operated leg raises the risk of a clot at exactly the point when that risk is already at its highest, and airlines can refuse boarding to a passenger who cannot manage the aisle. Most surgeons will clear a short flight of a few hours from around two weeks, once the wound is healed and you are walking comfortably with crutches, and will ask patients facing a long haul journey to wait longer, often to four to six weeks. An aisle seat, blood thinning medicine as prescribed, compression stockings and standing up every hour are the standard precautions on the flight itself.

Allowing 14 to 16 days instead is worth considering. Stitches or clips normally come out around day twelve to fourteen, and having that done by the team who operated removes the one appointment most likely to go wrong once you are home.

Book a flexible return ticket. Wounds sometimes need a few extra days and a fixed date turns a small delay into a real problem.

What moves the price

Price differences between two quotes for the same operation almost always come from six things. The implant matters most, because a ceramic on highly cross linked polyethylene bearing costs more than a standard metal on polyethylene one, and cemented, uncemented and hybrid fixation all price differently. Robotic assistance adds the cost of the planning CT, the disposable instruments used with the arm and the extra theatre time. Then come the number of nights on the ward, whether one hip or both are being replaced, whether your other medical conditions need specialist input during the stay, and how much physiotherapy is included.

A package quote from a Turkish hospital normally covers the airport transfers, the pre-operative tests, the surgeon and anaesthesia fees, the implant, the nights on the ward, physiotherapy starting the day after surgery, an interpreter, a set number of hotel nights, and the follow up appointments before you fly. What it normally leaves out is the flight, travel insurance, an extra hospital night if one becomes necessary, and the treatment of a complication.

Read what a quoted figure covers before comparing it with another. The questions that separate a real price from a headline one are whether the implant brand is named, whether the pre-operative tests and the planning CT are inside the figure, how many physiotherapy sessions are counted, what happens financially if you need an extra night, and whether the follow up consultations before you fly are included.

Medical tourism price aggregators publishing 2026 figures put a single hip replacement at Istanbul hospitals at roughly 7,500 to 15,000 US dollars, and they price the robotic version 10 to 20 percent above the conventional one, which puts most robotic quotations in the 10,000 to 15,000 band. The same operation in the United States, the United Kingdom or Western Europe costs several times that. Those are indicative figures compiled from public sources rather than quotations, they move with the implant and the hospital, and none of them has seen your X-rays.

Arranging the trip

Bring somebody with you. For the first fortnight after a hip replacement you will need help with shopping, bags, stairs and getting to appointments, and a companion is the single practical thing that makes a trip like this work. Hotel rooms near the hospital should be checked for lifts and for step free access to the bathroom, since a walk-in shower matters more than the view when you are on crutches.

Ask the hospital directly about the things that differ by country and by household instead of assuming them. Which languages the international patients team works in, whether a female surgeon can be requested, how meals accommodate a restricted diet, where a companion sleeps and whether that is inside the quoted price, and what the hospital sends for a visa invitation letter and how long that takes.

How the remote assessment usually works

Hospitals in Turkey that treat international patients run the first stage the same way, and knowing the sequence makes it easier to judge whether you are being handled properly. A coordinator receives your reports and imaging, routes them to the relevant unit, and a specialist reads them. What comes back is a written opinion, a proposed plan and an itemised estimate, in your own language, before anything is booked. At most of these hospitals that review costs nothing. A quote that arrives with no written clinical opinion behind it is worth questioning.

Travel insurance deserves a careful read before you book. Ordinary policies commonly exclude anything arising from planned treatment abroad, so check whether complications after surgery are covered, and if they are not, ask what a longer stay would cost if it became necessary.

After you fly home

Aftercare is where a hip replacement abroad succeeds or fails, so settle it before you travel. Ask for your discharge summary, the operation note, the implant identification labels and the post-operative X-ray as files you can keep, in English, because a doctor at home who has none of that is working blind. Ask who you message when something worries you at eleven at night, and how quickly somebody replies.

Remote follow up for a hip replacement is mostly photographs and questions. A picture of the wound at two and six weeks, a note of how far you are walking, and a report from any physiotherapist you see locally are enough for the surgical team to tell whether recovery is on track. Standard checks after that are an X-ray at around one year and then every few years, and those can be done at home and sent on.

Some things need a local doctor the same day instead of a message. Spreading redness or a wound that reopens, fever above 38 degrees, calf pain with swelling on one side, sudden breathlessness, or a leg that has become short and turned in after a twist. Go to an emergency department for any of those and tell them you have had a hip replaced, because that fact changes what they look for.

Registry data still gives the best answer to the question everyone asks about how long the new hip will last. Pooled national registry figures published in The Lancet in 2019 show around 58 percent of hip replacements still in place 25 years after surgery, and case series report higher figures than that. Your own odds depend on your age, your weight, your activity and the implant used, and none of the robotic systems has been in use long enough to have its own 25 year number.
