Apollo Hospitals deploys robotic surgery system for joint replacements
The surgeon remains in control—treatment decisions stay with the person holding the instruments.
Mark
So the robot is doing the surgery?
Mimi
No, that's the key thing. The surgeon does the surgery. The robot is more like a very precise assistant that helps execute a plan.
Luke
But we should be clear—the source doesn't actually say what the clinical outcomes are yet. It says the system is designed to improve precision, but we don't have data on whether patients actually heal better or faster.
Mimi
Right. What we know is that Apollo has deployed the technology and the surgeons are learning where it adds value. That's the current state.
Mark
Why would a surgeon need a robot to help with something they've been doing by hand for decades?
Mimi
Consistency, partly. A robot can execute the same movement the same way every time. And implant positioning matters—even small variations can affect how long the replacement lasts.
Luke
But again, we'd want to see the data on that. The source talks about potential and design intent, not proven outcomes.
Mark
How many surgeries have they done with this system?
Mimi
The source doesn't give a number. It mentions this is an expansion of their program, so they've done some, but we don't know how many.
Luke
That's a gap. Without volume, it's hard to assess whether they've actually learned what works and what doesn't.
Mark
Is this common in hospitals now?
Mimi
Robotic surgery exists in other specialties—urology, gynecology. But for joint replacement specifically, it's still relatively new. Apollo is positioning itself as an early adopter in Chennai.
Luke
The source doesn't compare this to what other hospitals in the region are doing, so we can't really say whether Apollo is ahead or just keeping pace.

- Traditional joint replacements have always depended entirely on individual surgical skill, creating natural variation in outcomes that robotic precision now has the potential to reduce.
- Apollo's adoption of Mako SmartRobotics introduces a pre-operative planning phase using 3D CT imaging, shifting part of the surgical process out of the operating room and into careful digital preparation.
- A robotic arm guides execution during surgery, but surgeons retain full decision-making authority — the tension between automation and human judgment is deliberately resolved in the human's favour.
- Senior surgeon Arun Kannan cautions that the technology's value is not universal — identifying the right patients and the right moments in a procedure is itself a clinical skill the team is actively developing.
- Apollo marked the expansion with a gathering of six senior orthopaedic robotic surgeons, signalling institutional commitment and the beginning of a knowledge-sharing effort around strategic deployment.
At Apollo Hospitals in Chennai, the ancient partnership between healer and tool has taken a new form — surgeons now plan joint replacements in three dimensions before the first incision, then guide a robotic arm that translates their judgment into millimeter-level precision. The Mako SmartRobotics system, developed by Stryker, does not supplant the surgeon's authority but extends it, offering consistency where human technique has historically varied. This quiet expansion of orthopaedic capability invites a broader question the hospital is already asking: not whether the machine can help, but precisely when and for whom its help matters most.
Apollo Hospitals on Greams Road in Chennai has expanded its orthopaedic capabilities by introducing robotic-assisted surgery for knee and hip replacements. The system at the centre of this shift is Mako SmartRobotics, built by Stryker, which pairs three-dimensional CT imaging with detailed pre-operative planning to give surgeons a precise blueprint before they enter the operating room.
The process begins with imaging. Surgeons map each patient's unique anatomy, plan bone preparation, and determine implant positioning in advance. When surgery begins, a robotic arm helps carry out that plan with a level of consistency difficult to achieve by hand alone — while the surgeon retains full control over treatment decisions and clinical judgment throughout.
Senior orthopaedic robotic surgeon Arun Kannan noted that working with the technology has sharpened the team's understanding of where it genuinely adds value. Robotic assistance is not uniformly beneficial across every patient or every moment in a procedure; the skill lies in knowing when to deploy it. For patients, better implant positioning can mean a longer-lasting, better-functioning replacement. For surgeons, it offers a way to standardise aspects of a procedure that have historically depended on individual technique.
Ilankumaran Kaliamoorthy, who leads Apollo's Chennai operations, described the adoption as part of a wider commitment to equipping surgeons with better tools. The hospital marked the occasion with a gathering of six senior orthopaedic robotic surgeons who delivered keynote addresses — a signal that this is not merely a technology acquisition, but the beginning of a more deliberate, experience-driven approach to robotic surgery.
Apollo Hospitals on Greams Road in Chennai has begun using robotic assistance for knee and hip replacement surgeries, marking an expansion of the hospital's orthopaedic capabilities. The system, called Mako SmartRobotics, is made by Stryker and works in tandem with three-dimensional CT imaging and detailed planning done before the patient enters the operating room.
The workflow begins with imaging and analysis. Surgeons use the three-dimensional scans to map out each patient's unique anatomy, then plan exactly how bone will be prepared and where the implant will be positioned. This pre-operative blueprint becomes the guide for what happens next. When surgery begins, a robotic arm assists the surgeon in carrying out that plan with precision. The system is built to provide real-time information and guidance during the procedure, but the surgeon remains in control—treatment decisions and surgical judgment stay with the person holding the instruments.
Arun Kannan, a senior orthopaedic robotic surgeon at the hospital, explained that the team's experience with the technology has taught them something practical: robotic assistance works best when deployed strategically. Not every patient needs it, and not every step of every procedure benefits equally from it. The value comes from understanding which cases and which moments in surgery are where the robot's precision adds something the surgeon's hand alone cannot achieve.
Ilankumaran Kaliamoorthy, who leads Apollo Hospitals' Chennai operations, framed the adoption as part of a broader commitment to giving surgeons better tools. The hospital marked this expansion with a gathering of senior orthopaedic robotic surgeons—Arun Kannan, Kornad Kosygan, Kunal Patel, Navaladi Shankar, Vijay Kishore Reddy, and Madhan Thiruvengada—who delivered keynote addresses on the topic.
The introduction of robotic assistance to joint replacement surgery represents a shift in how these procedures can be approached. Traditional knee and hip replacements rely entirely on the surgeon's skill and experience. Adding robotic guidance does not replace that skill; instead, it creates a partnership where the surgeon's judgment is augmented by the robot's ability to execute a plan with millimeter-level consistency. For patients, the potential benefit lies in better implant positioning, which can affect how long the replacement lasts and how well it functions. For surgeons, it offers a way to standardize certain aspects of a procedure that have historically varied based on individual technique.
