What is Robotic Partial Knee Replacement?
One of the biggest advantages of Smith+Nephew’s Robotic-Assisted Partial Knee Replacement is that it does not require a CT scan or MRI before surgery. This means fewer steps, less radiation, and faster planning. During the surgery, the robot uses real-time sensing to map the knee and assist the surgeon in removing only the damaged part of the knee — whether it’s the inner side (medial), outer side (lateral), or kneecap (patellofemoral). The healthy bone, cartilage, and ligaments are preserved, which helps your knee feel more natural after the operation.
This is a minimally invasive and highly accurate procedure that is ideal for patients of all ages, even younger individuals who want to stay active. Because it’s so precise, there is less pain, quicker recovery, and a lower risk of complications. Whether you’re in your 30s, 50s, or 70s, this advanced robotic solution makes knee surgery safer, faster, and more personalized — and you can walk into surgery without needing CT or MRI scans.

The minimally invasive nature of the procedure also means less pain and reduced hospital stays. Patients can return to their daily activities much sooner with enhanced confidence and mobility. Our dedicated team ensures personalized care at every step, making your journey to recovery smooth and comfortable.
Robotic Technology for Partial Knee Fix
AI-based Robotic Partial Knee Replacement is transforming orthopedic care by targeting only the damaged portion of the knee—preserving healthy bone, cartilage, and ligaments. With real-time 3D imaging and dynamic mapping, the CORI system guarantees perfect implant placement and balanced soft tissue tension, delivering natural knee movement and faster recovery with minimal discomfort.
Pioneered by Dr. Meghal Goyal, this cutting-edge approach achieves sub-millimeter precision, reducing surgical risks and extending implant longevity. Its minimally invasive nature means less blood loss, reduced pain, and a quicker return to daily activities compared to traditional total knee procedures.
Tailored to each compartment—inner (medial), outer (lateral), or kneecap (patellofemoral)—this robotic technique personalizes every step of the operation, minimizes human error, and ensures consistently superior outcomes.
How does Robotic technology improve knee replacement surgery?
Robotic-assisted systems like CORI use advanced 3D digital modeling to create a customized surgical plan tailored to your unique knee structure.
This means the size, shape, and alignment of the implant are planned precisely before the first cut is even made.
Unlike traditional surgery, robotic tools assist surgeons in executing highly precise bone cuts within sub-millimeter accuracy.
This reduces the chance of errors, preserves more healthy bone and ligaments, and ensures the implant fits perfectly.
Because robotic surgery is highly accurate, it helps maintain proper alignment and balance in the knee joint. This supports a more natural walking pattern and joint movement after the procedure. By preserving healthy tissues and focusing only on the damaged parts, robotic partial knee replacement feels closer to your original knee.
Robotic-assisted surgeries are often less invasive, leading to smaller incisions and reduced damage to surrounding tissues. This means patients experience less pain and swelling after the procedure, helping them recover more quickly.
How is the surgery planned before the procedure?
High-resolution X-rays and MRIs evaluate the damaged knee compartment. These images help determine the extent of arthritis or injury. Doctors assess bone quality, cartilage loss, and ligament integrity. This ensures the right candidates are chosen for partial replacement.
Advanced software converts your scans into a patient-specific 3D knee model. Surgeons review bone contours, joint alignment, and ligament tension. The virtual model allows precise measurement of implant size and position. This digital plan forms the blueprint for the robotic procedure.
In the OR, the robot is aligned to your actual knee anatomy. Sensors register key landmarks on your bone surface in real time. This maps the preoperative 3D plan directly onto your knee. Calibration guarantees the robot follows the exact surgical plan.
Surgeons simulate bone cuts and implant placement on the robot’s console. They check alignment angles, soft-tissue balance, and range of motion. Any necessary tweaks are made virtually before the first incision. Final validation ensures optimal fit and function for your new joint.
What are the benefits of partial knee replacement?
Partial knee replacement focuses only on the damaged compartment of the knee, leaving the healthy bone, cartilage, and ligaments intact.
By preserving the undamaged structures, your knee retains more of its natural anatomy and biomechanics. This targeted approach reduces the stress on surrounding tissues and helps maintain normal joint function.
Because the procedure is less extensive, there is less blood loss during surgery. The smaller surgical field and shorter operative time decrease the chance of infection. Reduced tissue handling lowers the risk of postoperative stiffness and deep vein thrombosis. Overall complication rates are lower compared to full knee replacements.
Targeted replacement of only the damaged area leads to optimal alignment and balance within the joint. This precision results in smoother motion and better load distribution across the knee. Patients frequently notice enhanced stability and a more natural gait post-operatively. Enhanced function often translates into greater confidence in everyday movements.
With less tissue trauma, patients often mobilize and start physical therapy sooner. Many individuals are walking with assistance within 24 hours of surgery.
Rehabilitation protocols can be accelerated, allowing a quicker return to daily activities and low-impact exercise.
