For patients who have bad knee arthritis, knee replacement surgery in Firozabad now has a choice that wasn’t there ten years ago. Patients can choose between robot-assisted surgery or regular surgery that a doctor does with their hands. Many patients come in asking for the robot thinking it is the best option. As doctors we need to give patients answers based on evidence not just what is being advertised.

Both techniques aim to relieve pain and restore movement, but they differ in how the bone cuts are planned, how precisely the implant is aligned, and what the recovery experience looks like in the days after surgery. An experienced orthopedic doctor in Firozabad can help match the right technique to your knee, your activity goals, and your surgeon’s experience.

“The robot helps the doctor make accurate cuts. It does not guarantee results for every patient. What makes the biggest difference is the doctors experience. Using good ways to line up the implant no matter which tool is being used.“
— Dr Parv Mittal, Consultant Orthopedic Surgeon, Firozabad

In conventional total knee arthroplasty, mechanical instrumentation has been developed, refined, standardized for decades and it is used by surgeons. The surgeon places cutting blocks against the fixed anatomical landmarks, cuts the damaged bone surfaces and inserts the implant in accordance with methods proven in millions of surgeries throughout the world. It is still the most commonly performed technique worldwide and has a long history of long-lasting, well understood success.

Many of the concepts in robotic surgery that have made it appealing have also been incorporated into the more traditional approach; for example, the concept of personalised alignment and intentional protection of soft-tissue landmarks have been used in the standard procedure in recent years.

• Time tested: Decades of long-term survivorship and complication data from a wide range of patient populations.
• Broad applicability: Applies to most patient types, activity levels and knee anatomies including those with previous surgeries and/or hardware.
• Efficient: This usually means an operative time that is shorter on the table, which may be important for patients with other health concerns.
• Widely available: Not reliant on the presence of robotic equipment, so scheduling is not a big factor. 

In robotic knee surgery at Firozabad, the surgeon plans the cuts and alignment of the bones before cutting anything using the images of the patient’s knee acquired before surgery. The system allows the surgeon to receive real-time feedback during surgery, and helps to contain the surgeon’s instruments in the surgical range of motion so the room is less available for freehand deviation. The surgeon is always at the helm during the procedure the robot works under his guidance, it does not do it by itself.

This precision has facilitated the reliable planning and delivery of personalised, kinematic alignment strategies which were technically not routinely achievable with manual instrumentation alone. 

• Precision guided cuts: Minimizing outlier alignment and deviation from the intended axis, when compared to conventional jigs.
• Personalized alignment: Simplifies the implementation of kinematic/functional alignment planning to a native patient’s anatomy, repeatability and reproducible manner.
• real time feedback: Fine intra-operative adjustments to ligament balance and limb alignment.
• Growing option: Increasingly used in complex deformities or where more precise control of bone resection is required, Growing option is offered.

• Patients with prior soft-tissue concerns: Where deliberate, minimally invasive ligament balancing is desired, patients with previous soft tissue problems are the ideal candidates for the procedure.

Total knee replacement (TKR) surgery is a safe, predictable, and equally effective option for most patients. 

• For normal anatomy: The two techniques are equally effective when the knee is not significantly deformed.
• Shorter surgery:  A shorter time for the operation, which may be significant for patients with cardiac or anaesthetic or other health issues.
• Established outcomes: The longest duration and largest patient population of long-term survivorship and complication data for different patient groups.
• Cost and access factors: These are items that are available at all hospitals that are equipped, and not dependent on robotic scheduling.
• Surgeon familiarity: twenty or more years of practice have made the experienced surgeon adept at perfect alignment without the aid of the telescope.

In a large propensity matched study of Total Knee Arthroplasty patients at Cleveland Clinic, the robot was beneficial for shorter length of stay and higher same-day home discharge rates, and manual surgery was beneficial for greater 90 day flexion and operative time, with no difference between groups in pain scores, opioid usage, or 90 day complication rates. The Cleveland Clinic Consult QD (Cleveland Clinic Question of the Day) noted that the two surgeries are almost equal in terms of patient outcomes.According to the Cleveland Clinic Consult QD (Question of the Day), patient outcomes are almost the same with both surgeries.

The trend is similar across the research literature; numerous randomized controlled trials and meta-analyses, including a pooled analysis of more than 2,600 knees conducted in 2025 and a long-term randomized study (RT) in which more than 1,400 patients were followed for 10 years, all demonstrate that although robotic platforms can achieve better mechanical alignment, patient-reported outcomes, pain scores and implant survivorship are statistically equivalent at 1-year post-surgery.

• Structured rehabilitation: Both procedures use a similar physiotherapy program to regain strength, flexibility and confidence in the joint, which usually takes many weeks.
• Go back to daily activities: Most patients return to light daily activities in a few weeks and progressively increase their strength over the next few months.

The overall weekly trend is similar for both techniques. Our knee replacement recovery, week by week guide provides a detailed explanation of what you can expect each week. 

Both techniques involve risks of any large joint surgery (infection, blood clots, stiffness, and eventual implant wear), but some risks are specific to the techniques.

• New-technology learning curve: As robotic technology continues to be developed, and as more surgeons gain experience with the devices in future years, things may get even better.
• Soft-tissue preservation matters most: It’s not the robot itself, but rather soft-tissue preservation (i.e., avoiding unnecessary ligament releases), which is most strongly associated with greater pain and function scores, according to research. Robotic platforms make this much easier to accomplish on repeat.
• Alignment philosophy matters more than the tool: Whether performed with robotic arm assistance or with traditional instrumentation in the hands of an experienced surgeon, alignment philosophy is more important than the tool: Functional outcomes can be similar using a personalised or kinematic alignment strategy.
• There is also a role for implant choice: In pooled data, the functional scores at short-to-mid-term time points have been similar between the two implant designs, while the rates of complications have been equivalent, and cruciate-retaining implants have demonstrated superior 10-year survivorship.
• Metal and hardware considerations: Like any implant, patients with specific anatomical concerns or those who are sensitive to metal should discuss with their surgeon what implant material and design is best for them.
• Watching for problems: Any ongoing pain, clicking, swelling or decreased movement months following either procedure should always be evaluated timely and not attributed to wear and tear, as issues can be detected and addressed early.
