What is robotic knee replacement surgery and how does it work?
Robotic knee replacement surgery is an operation in which a worn knee joint is replaced with a metal and plastic implant, with a robotic arm helping the surgeon to prepare the bone. The robot does not operate on its own. Before or during the operation a three-dimensional plan of your knee is built, either from a CT scan or from points the surgeon maps on the bone, and the surgeon sets the implant size, position and alignment. During surgery the robotic arm holds the saw or burr inside the planned boundary, so the bone cuts follow the plan closely and stop at its edge. Hospitals in Turkey offer robotic-arm assistance for both total and partial knee replacement.
This guide explains how the operation works, what the evidence says, what it costs compared with the UK, US and Germany, what recovery involves and how to check a hospital. The wider range of operations is in our orthopedics treatments in Turkey hub.
Does robotic knee replacement surgery work, and how does it compare with conventional surgery?
The honest answer is that it works very well, but a long-term advantage over the conventional method is not yet proven. Knee replacement itself is a long-established operation that relieves pain and improves movement for most people with advanced arthritis. Studies of robotic-arm systems consistently show more accurate bone cuts and implant alignment than manual instruments, and some report slightly less early pain and a quicker return of movement.
What is less certain is whether that accuracy leads to longer-lasting knees or better function years later. Large registry data have not yet shown a clear difference, and many experienced surgeons get excellent results without a robot. The operation can also take a little longer. A trustworthy surgeon will present the robot as a precision tool, not as a guarantee of a different knee.
Who needs a knee replacement, and who is a good candidate?
Surgery is usually considered when arthritis has worn the cartilage so that pain limits walking, sleeping or daily life, and when exercise, weight management, physiotherapy, painkillers and injections have not given enough relief. X-rays show how narrow the joint space is, but the decision rests on your symptoms as much as the images.
You are less suited if you have an active infection anywhere in the body, poorly controlled diabetes or heart disease, severe circulation problems in the leg or a very weak thigh muscle that cannot be rehabilitated. Smoking and a high body weight raise the risks, and many surgeons ask you to address them first. Younger, active patients with damage limited to one side of the knee may be offered a partial replacement or an alternative such as tibial osteotomy, which realigns the bone instead of replacing the joint.
Robotic knee replacement surgery cost in Turkey compared with the UK, US and Germany
The figures below are approximate ranges for one knee, not hospital quotes. The price depends on whether the replacement is total or partial, the implant brand and robotic system, the length of hospital stay, rehabilitation and the package. Each hospital confirms its price in a written quote.
| Country | Approximate cost range |
|---|---|
| Turkey | €9,000 – €18,000 |
| United Kingdom | €13,000 – €24,000 |
| United States | €30,000 – €65,000 |
| Germany | €14,000 – €28,000 |
A package normally includes pre-operative tests, the implant, the robotic-assisted operation, anaesthesia, hospital nights, inpatient physiotherapy, medication and transfers. Ask which implant is used, whether a revision warranty exists, what blood-thinner and compression stocking supplies are provided and whether a second knee costs less. Our free quote page asks the hospital to list these items in writing.
Robotic, conventional or partial knee replacement: what are the differences?
Three choices are common. Conventional total knee replacement uses mechanical guides, robotic-arm total knee replacement uses the plan and the robotic arm, and partial replacement resurfaces only the damaged compartment. If you are considering a partial replacement with a robotic arm, see our page on knee Makoplasty.
| Option | Best suited to | Typical limits |
|---|---|---|
| Robotic-assisted total knee | Arthritis across the whole joint, desire for planned alignment | Longer set-up, device cost; long-term advantage not proven |
| Conventional total knee | Most patients with advanced arthritis | Alignment depends more on surgeon technique |
| Partial knee replacement | Damage limited to one compartment, intact ligaments | Not suitable if arthritis has spread; may need later conversion |

How is the operation done step by step?
You are given a spinal anaesthetic with sedation or a general anaesthetic. If the system uses a CT-based plan, the scan is done beforehand and the plan is reviewed by the surgeon; others map the bone surface during surgery. A cut is made over the front of the knee, the damaged cartilage and a thin layer of bone are removed within the robotic boundary, the surgeon checks the balance of the ligaments with the trial implants and then fixes the final components, often with bone cement. The wound is closed and a dressing applied. The operation usually takes one to two hours, and most hospitals start walking with a frame the same or the next day.
What results can you realistically expect?
Most people notice that the arthritic pain has gone within weeks, while swelling and stiffness take longer to settle. By three months many people walk comfortably without aids and manage stairs; by six to twelve months the knee feels at its best. A knee replacement does not feel identical to the original joint; you may notice occasional clicking, a different sensation when kneeling and a limit to deep bending. Surgeons usually advise against high-impact sport such as running. Implants commonly last fifteen to twenty years or longer, but how long yours lasts depends on your weight, activity and bone quality.
Robotic knee replacement surgery recovery: how long should you stay in Turkey?
Most patients stay in hospital for three to five nights and remain in Turkey for ten to fourteen days so that the wound, swelling and walking can be checked before the flight. Walking starts on the day of surgery or the next day, supported by a physiotherapist.
- Week 1: walking with a frame or crutches, painkillers, blood-thinning injections or tablets and exercises to bend and straighten the knee.
- Weeks 2 to 6: stitches or clips removed, swelling and bruising ease, you progress to one stick and then none.
- Weeks 6 to 12: driving and light activity usually resume if the surgeon agrees.
- 3 to 12 months: strength and bending continue to improve with physiotherapy at home.
Flying carries a clot risk in the weeks after joint surgery, so the surgeon will advise on timing, compression stockings and blood thinners. A video check-in and a physiotherapy plan for home are part of good follow-up.
What are the risks and complications?
Common effects are pain, swelling, bruising and stiffness. More serious but uncommon problems include infection, blood clots in the leg or lung, nerve or blood-vessel injury, loosening or wear of the implant and a knee that stays stiff. The NHS and the American Academy of Orthopaedic Surgeons explain that the risk is small but real and is lowered by good fitness, not smoking, careful wound care and following rehabilitation advice. Robotic assistance does not remove these risks. Ask the surgeon how many robotic knees they have performed and what happens if an implant needs revision, which is discussed in our guide to revision knee replacement.
How to choose a hospital and what to ask
Check that an orthopaedic surgeon specialising in joint replacement will operate, that the hospital is licensed and has anaesthesia, intensive-care and physiotherapy on site, that the implant brand and size are named in the quote and that you receive a written plan before you pay a deposit. Red flags include promising that the robot guarantees a perfect result, no review of your X-rays, an unclear price and no follow-up plan. See how our process works for the steps from your X-rays to surgery.

Frequently asked questions
It is a knee replacement in which a robotic arm helps the surgeon prepare the bone according to a three-dimensional plan. The surgeon stays in control, and the arm keeps the saw within the planned boundaries.
It gives more accurate implant alignment, and some studies show slightly less early pain. Evidence that it makes the knee last longer or work better years later is not yet clear.
Approximate costs are €9,000 to €18,000 per knee in Turkey, against about €13,000 to €24,000 in the UK. The price depends on the implant, the system, the hospital stay and the rehabilitation included.
You are under anaesthesia during the operation. Afterwards pain is controlled with medication and nerve blocks, and most people find the arthritic pain gone within weeks, though swelling lasts longer.
You walk with a frame the day after surgery, use a stick after two to six weeks and resume driving at around six to twelve weeks. The knee keeps improving for up to a year.
Plan for about ten to fourteen days, including three to five nights in hospital, so the wound and mobility can be checked before the flight.
Knee implants commonly last fifteen to twenty years or longer. Lifespan depends on weight, activity, bone quality and the implant, not only on whether a robot was used.
People with an active infection, uncontrolled medical conditions, severe leg circulation problems or mild arthritis that still responds to other treatment may be advised against it. The surgeon decides after examination and X-rays.
Some hospitals offer it for selected fit patients, but it increases the strain of recovery and the clot risk. Many surgeons prefer to operate on one knee at a time.
It is usually allowed after the surgeon has checked the wound, often after about ten to fourteen days. Clot prevention with stockings, movement and sometimes blood thinners is advised.
