What Patients Should Ask Their Surgeon About Robotic Joint Surgery: 12 Essential Pre-Op Questions

If you’re suffering from joint pain or arthritis that limits your movement and daily activities, you may have heard about robotic joint surgery — one of the most advanced surgical options available today. But before you decide, it’s important to understand what to expect, how it works, and how recovery looks after surgery.

To make your journey easier, we’ve compiled the 12 most important questions every patient should ask their surgeon before robotic joint surgery — along with simple, medically accurate answers.

Q1. What Is Robotic Joint Surgery and How Does It Work?

Robotic joint surgery is a cutting-edge, computer-assisted procedure that helps surgeons perform joint replacements with unmatched accuracy. The system creates a 3D model of your joint, helping the surgeon plan the surgery precisely to your anatomy.

During surgery, the robotic arm guides the doctor to remove damaged tissue and place the implant at the perfect angle. The surgeon stays fully in control — the robot simply enhances precision. This ensures less pain, smaller cuts, faster healing, and better long-term movement compared to traditional surgery.

Q2. How Many Days of Rest Are Required After Knee Replacement?

After robotic knee replacement, most patients stay in the hospital for 2–3 days. Rest is important during the first week, followed by gentle physiotherapy.

(For detailed recovery milestones, see Question 12 below.)

Q3. Which Is Better — Traditional or Robotic Knee Replacement?

Both traditional and robotic knee replacements aim to restore function and relieve pain, but robotic joint surgery offers far greater precision.

The robotic system provides a 3D image of your knee and helps the surgeon align the implant more accurately, which improves stability and longevity. Traditional methods rely solely on manual skill and standard guides, which can vary slightly between patients. Robotic surgery ensures more personalized results, less pain, and a quicker return to activity.

Q4. What Is the Age Limit for Robotic Knee Replacement?

There isn’t a strict age limit for robotic knee replacement. Typically, it’s suitable for patients aged 45 to 80, depending on bone strength and overall health.

Your eligibility depends more on joint condition, activity level, and medical fitness than on age alone. Even older adults in good health can be excellent candidates. Your orthopedic surgeon will assess your knee’s condition and your general health before recommending surgery.

Q5. Which Type of Implant Is Commonly Used?

Most robotic knee replacements use fixed-bearing or mobile-bearing implants, made from durable metal alloys and medical-grade polyethylene.

• Fixed-bearing implants are ideal for older or less active patients.
• Mobile-bearing implants offer greater flexibility for younger, more active individuals.

Your surgeon will select the implant that best matches your bone structure, age, and activity goals, ensuring comfort, stability, and long-term success.

Q6. Why Do Surgeons Prefer Robotic Surgery?

Surgeons increasingly prefer robotic surgery because it offers enhanced accuracy, control, and patient safety.

With real-time 3D imaging and robotic assistance, the implant is placed with near-perfect precision, reducing risks like misalignment or uneven wear. It also minimizes tissue trauma, speeds up recovery, and leads to better long-term joint function.

For patients, this means less pain, smaller scars, fewer complications, and quicker rehabilitation.

Q7. What Happens During Surgery, and How Long Does It Take?

During robotic joint surgery, the surgeon uses a robotic arm to carefully remove damaged bone and cartilage and replace it with an artificial implant.

The robot helps maintain perfect alignment and depth, ensuring a more natural joint motion. The surgery typically lasts about 1.5 to 2 hours. You’ll be under anesthesia throughout the procedure, so you won’t feel pain.

After surgery, most patients are encouraged to walk with assistance within 24–48 hours.

Q8. What Is Artificial Knee Surgery?

Artificial knee surgery, also called knee replacement, involves replacing worn-out or damaged knee surfaces with metal and plastic components.

Artificial knee surgery, also called knee replacement, involves replacing worn-out or damaged knee surfaces with metal and plastic components.

These implants act as a smooth, durable joint surface, allowing pain-free movement and stability. It’s usually recommended when arthritis or injury causes severe pain or stiffness that doesn’t respond to medication or therapy.

Robotic-assisted techniques make this surgery more precise and minimally invasive, helping patients recover faster and enjoy better long-term outcomes.

Q9. How Much Pain Will I Have After Surgery?

Pain after robotic joint surgery is typically milder than with traditional surgery. Advanced anesthesia and pain management help minimize discomfort during and after the operation.

Most patients report pain levels around 3 out of 10 within the first few days, and noticeable improvement within 3 to 6 weeks. Following your physiotherapy routine and your doctor’s advice will help control swelling and speed up healing.

Q10. What Should I Expect Immediately After Surgery?

Right after surgery, you’ll spend a short time in the recovery room under observation. You might feel mild stiffness or soreness — which is normal.

Your medical team will help you manage pain and start light movement, often within 24–48 hours. Most patients can go home after 2–3 days, depending on their progress.

Q11. What Activities Will I Be Able to Do After Surgery?

Once you recover, you’ll be able to resume most daily and low-impact activities, including:

• Walking
• Climbing stairs
• Swimming
• Swimming
• Gardening

High-impact sports like running or jumping should be avoided to protect your implant. Most patients regain 90% of their knee function in 3–6 months and experience long-term pain relief and stability.

Q12. What Can I Expect During Recovery?

Recovery after robotic joint surgery is usually faster than traditional methods.

Here’s a general timeline:

• Day 1–3: Begin assisted walking and light physiotherapy.
• Week 2–3: Walk more independently with minimal support.
• Week 6–8: Resume most daily routines.
• Month 3–6: Regain full strength, flexibility, and joint stability.

Following your physiotherapy plan, eating a protein-rich diet, and attending follow-ups are key to a smooth recovery
