Robotics does not replace the surgeon, but rather acts as an advanced tool that enhances their capabilities, allowing for a more predictable and controlled execution of each surgical step.

The adoption of robotics in hip and knee arthroplasty is marking a new era in orthopedic care, seeking to optimize outcomes for patients worldwide.

Preoperative Planning and Robotic Precision

Robotic knee replacement surgery marks a before and after thanks to detailed planning and unprecedented precision. Before stepping into the operating room, a three-dimensional map of your knee is created.

Advanced Imaging for Planning

We use high-resolution imaging studies, such as full-leg X-rays or CT scans. These images allow us to see your anatomy in astonishing detail. This is key to understanding the exact alignment of your leg and the shape of your bones.

Precise Implant Sizing

Based on these images, we can select the perfect knee implant size and shape for you. It's like having a custom-made template before the operation. This reduces uncertainty and improves implant fit.

Measurement of Deformities and Alignment

Robotics helps us accurately quantify any existing deformity or misalignment. We can measure angles and distances with a precision that the human eye cannot match. This is vital for restoring the natural alignment of your leg and optimizing ligament balance.

Robotic planning is not just an image; it's a virtual model of your surgery, allowing us to anticipate and resolve potential problems before they occur.

Execution of Robotic Knee Surgery

Robotic Navigation and Calibration

The execution phase of robot-assisted knee replacement surgery begins with the calibration of the robotic system. Small pins are placed in the patient's bone, which act as reference points for the robot. These pins allow the system to accurately map the patient's unique knee anatomy. This calibration is essential for the robot to follow the pre-established surgical plan with precision.

Collection of Bone Reference Points

Once calibrated, the robot begins to collect data. The surgeon guides the robotic arm to touch key points on the femur and tibia bones. The system records these locations, creating a detailed three-dimensional model of the patient's joint. This information is used to guide the subsequent steps with great precision.

Robot-Assisted Bone Preparation

Bone preparation is where robotic assistance truly shines. Using the guides provided by the robot, precise cuts are made in the bone. The robot controls the movement of the cutting tool, ensuring that the cuts are made exactly as planned. This minimizes the removal of healthy bone and protects surrounding soft tissues, such as ligaments and nerves. Robotic precision at this stage is superior to what can be achieved with manual methods.

The robot's ability to make cuts with millimeter precision reduces variability and increases consistency in surgical outcomes.

The benefits of this phase include:

• More precise bone cuts.

• Less damage to soft tissues.

• Better implant alignment.

The final implant placement is then performed in the prepared bone beds, ensuring an optimal and personalized fit for each patient, something that Dr. Santiago Manzanal considers key to long-term success.

Tangible Benefits of Robotic Surgery

The adoption of robotics in knee replacement surgery marks a significant advance, offering concrete advantages over conventional techniques. These benefits translate directly into a better patient experience and potentially superior results.

Greater Precision and Less Tissue Damage

Robotic assistance allows for millimeter precision in bone cuts and implant placement. The robotic system, guided by the surgeon, can perform movements with an accuracy that surpasses human capability, thus minimizing damage to surrounding soft and healthy tissues. This is fundamental for preserving the natural anatomy of the knee as much as possible.

• Improved precision in bone resection.

• Less impact on ligaments and soft tissues.

• Potential reduction in blood loss.

Faster Recovery and Less Pain

Thanks to the less invasiveness and precision of the robotic technique, patients usually experience less postoperative pain. This, in turn, facilitates earlier mobilization and a faster overall recovery. Many patients can resume their daily activities in a shorter period of time.

The ability to make bone cuts with unprecedented accuracy and to optimally position implants contributes directly to a more favorable postoperative experience for the patient.

Improved Personalized Implant Placement

Every knee is unique, and robotics allows the procedure to be adapted to the specific anatomy of each patient. Through detailed preoperative planning, which includes advanced imaging, the exact dimensions and orientation of the implant can be determined. The robotic system helps the surgeon execute this plan with exceptional fidelity, seeking a more natural and functional fit. Dr. Santiago Manzanal highlights the importance of this personalization to achieve the best long-term results in robot-assisted knee surgery.

• Optimized implant alignment according to the patient's anatomy.

• Consideration of leg length and ligament balance.

• Adaptation to pre-existing deformities for a more natural result.

Results and Patient Satisfaction

Optimization of Ligament Balance

Robotics in knee replacement surgery allows for more precise implant adjustment. This translates into better balance of the ligaments around the knee. Proper balance is key for the knee to feel natural and function correctly. Achieving this balance with robotic assistance can mean greater stability and a more natural feeling when moving.

Consistent Leg Alignment

One of the most discussed benefits of robot-assisted surgery is consistency in alignment. The robotic system helps the surgeon make bone cuts and position the implant with a precision that surpasses manual capabilities. This means the leg is aligned more predictably, which is important for implant longevity and overall knee function.

Positive Patient Experiences

Many patients who undergo robot-assisted knee replacement report a positive experience. This is often related to faster recovery and less postoperative pain compared to traditional methods. The ability to return to daily activities sooner is an important factor in patient satisfaction. If you are considering a knee replacement, Dr. Santiago Manzanal can evaluate if robotic technology is suitable for your particular case, always seeking the best results for you.

Considerations for Being a Candidate

Evaluation of Pain and Functional Limitation

Before thinking about robotics, the first thing is to understand why you need knee surgery. Is the pain constant? Does it prevent you from doing things you once enjoyed, like walking or climbing stairs? Functional limitation is key. If your daily life is significantly affected by discomfort and stiffness in your knee, it's a good starting point to consider treatment options. It's not just about having "some" pain, but about how that pain impacts your quality of life. Speaking openly with your doctor about these aspects is fundamental.

Diagnosis of Arthritis and X-rays

The diagnosis of arthritis, especially osteoarthritis, is the most common reason for knee replacement surgery. X-rays are the primary tool for evaluating the condition of your joint. These images show us how much cartilage you have lost, if there is new bone growth (osteophytes), and the degree of joint space narrowing. A clear X-ray showing advanced wear is an important indicator for considering surgery. Dr. Santiago Manzanal uses these images, along with your medical history, to determine the severity of the condition and if a knee replacement is the best solution.

Candidates for Total Knee Replacement

Not everyone with knee problems is a candidate for a total replacement. Generally, those considered are individuals who:

• Have experienced chronic pain and limited movement that does not improve with non-surgical treatments (such as physical therapy, medications, or injections).

• Have radiographic signs of severe arthritis in the knee.

• Their quality of life is significantly affected by knee pain and dysfunction.

• Are in a general state of health that allows them to undergo surgery and recover.

It is important to have realistic expectations. Robotic surgery, while offering great precision, is not a magic solution. The goal is to relieve pain and restore function, but recovery requires commitment and patience. Dr. Santiago Manzanal will evaluate your particular case to determine if you are a good candidate for this type of advanced procedure.

The Future of Robotic Knee Surgery

Innovations in AI and Machine Learning

Artificial intelligence (AI) and machine learning are beginning to play an important role in robotic surgery. These advances allow robotic systems to learn from each procedure, improving precision and personalization over time. Advanced algorithms can analyze preoperative and real-time data to predict outcomes and adjust surgical technique on the fly. This means that future surgeries could be even more tailored to each patient's unique anatomy, minimizing damage to healthy tissues and optimizing implant placement. Dr. Santiago Manzanal is attentive to these innovations to always offer the latest in technology.

Expansion to Other Joints and Surgeries

While knee replacement surgery has been a primary focus, robotics is expanding to other areas of orthopedics and surgery. We already see its application in hip replacements and it is expected to grow in shoulder, ankle, and spine surgeries. The precision and control offered by robotic systems are beneficial in a wide range of procedures, suggesting a future where robotic assistance is common in many types of surgeries.

Development of Specific Consumables

Parallel to the development of robotic systems, there is also a growing focus on creating specific consumables for these technologies. This includes personalized cutting guides, implants designed to interact with robotics, and advanced calibration tools. These consumables are designed to work in conjunction with the robot, maximizing its potential and simplifying the surgical workflow. The integration of these specific elements promises to make robotic surgery more efficient and accessible.
