Reverend Stryker and the Emergence of MAKO Robotics: A Fresh Perspective

Stryker Reaffirms Their Position as the Number 1 Medical Device Company Using MAKO SmartRobotics - Written by Ivan Dejan


Stryker Is Quietly Winning the Race in AI and Robotics for Orthopedic Surgery

As artificial intelligence (AI) continues its rapid integration into nearly every sector of society, healthcare stands as a domain where these technologies offer augmentation—not replacement—of human expertise. In particular, orthopedics is witnessing a transformative shift with the convergence of AI, robotics, and precision imaging. Leading this movement is Stryker, whose Mako SmartRobotics™ system is redefining how knee and hip replacements are planned, executed, and evaluated.



Redefining the Role of AI in Surgery

While public discourse often centers on AI as a job-displacer, in medicine the conversation is more nuanced. AI is not here to replace surgeons but to enhance the quality and efficiency of surgical interventions. From diagnostic decision support to predictive modeling of patient recovery, AI is increasingly being used to tailor medical care. Nowhere is this more evident than in orthopedic surgery, where the Mako system offers unprecedented precision, reducing procedure times by up to 30%, improving post-operative range of motion, and ultimately enhancing patient quality of life.



What Is Mako SmartRobotics™?

Traditionally, joint replacements relied on two-dimensional imaging—such as radiographs and CT scans—to assess joint alignment and deformities. Surgeons would interpret these images manually, making intraoperative decisions based on their training, experience, and tactile feedback.

Mako revolutionizes this paradigm. By converting CT scans into three-dimensional, patient-specific anatomical models, Mako enables individualized preoperative planning. It accounts for variables like bone spurs, composite density, and alignment deviations, providing a custom-fit implant strategy. This level of precision not only improves surgical outcomes but also minimizes unnecessary bone removal.

How It Works: Precision Engineered by AI

  1. Preoperative PlanningUsing CT imaging, Mako constructs a detailed 3D model of the joint. Surgeons can pre-select implant size and alignment, accounting for patient-specific deformities (e.g., varus or valgus angulation). The system allows fine-tuned adjustments to balance joint mechanics before the first incision is made.

  2. Intraoperative ExecutionDuring surgery, the system uses optical trackers and navigation arrays to register the patient’s anatomy in real time, ensuring spatial accuracy to within 0.05%. The robot interprets the surgeon’s manipulation of the limb—capturing coronal and sagittal alignments—and quantifies ligament tension, joint laxity, and natural contractures. This data is used to dynamically adjust implant position for optimal joint balance.

  3. AccuStop™ Haptic TechnologyMako’s robotic arm features haptic feedback, restricting bone cuts within the pre-defined surgical plan. This not only preserves healthy bone but also protects surrounding soft tissue. The system updates intraoperatively based on newly gathered tension data to refine positioning.

  4. Post-Resection EvaluationAfter resection, ligament integrity (PCL, ACL, MCL, LCL) is reassessed under tension. The system recalculates joint balance using updated laxity metrics, guiding final implant positioning to ensure both structural integrity and kinematic alignment.



Why It Matters: Moving Beyond Human Estimation

In conventional knee replacements, surgeons must rely heavily on tactile feedback and visual estimation—a process inherently limited in precision. As one surgeon aptly put it, “The human eye can’t reliably differentiate between 30° and 60° inside the joint—let alone a 5° variance.”

Mako addresses this gap. It provides real-time data and visualizations that quantify previously immeasurable variables. Moreover, it offers access to posterior and transverse joint structures that are difficult to visualize with anterior surgical approaches, reducing the risk of implant misalignment or debris retention.

With shorter surgical times, the system also reduces anesthesia duration and overall procedural cost—benefits that ripple through hospital systems and improve patient throughput.



The Numbers: A Snapshot of Mako's Impact

  • Procedure time reduction: Up to 30%

  • Post-op complication rates: Significantly decreased compared to traditional methods

  • Improved patient satisfaction: Higher reported mobility scores and reduced pain over time

  • Surgeon accuracy: Within sub-millimeter and sub-degree variances in implant positioning

A Medical Student’s Perspective: Man and Machine, Not Man vs. Machine

As a future physician, I don’t see Mako or AI as threats—but as tools that redefine our professional value. These technologies will not replace surgeons; they will refocus us—enabling us to spend less time on repetitive, manual tasks and more on critical thinking, post-op care, and patient counseling.

Mako doesn’t wield a scalpel alone. It requires operators—skilled, thoughtful, and trained. We remain central to its success, both in execution and accountability. As long as regulations like HIPAA limit full autonomous access to medical records, a completely AI-driven surgery remains science fiction.

And let’s be honest: if AI-enhanced surgery could have given Derrick Rose five more years in the NBA, that’s a future worth investing in.



Final Thought

Stryker’s Mako SmartRobotics™ isn’t just a surgical tool—it’s a blueprint for the future of precision medicine. In a world rapidly shifting toward data-driven decision making, Mako proves that collaboration between human intellect and machine precision isn’t a threat—it’s a breakthrough.
