Many people endure the pain of "osteoarthritis" because they are "afraid of surgery." However, did you know that knee replacement surgery today is one of the most successful procedures? Patients can now choose treatment options that meet their needs and offer good value. This includes selecting the materials for the knee implant, special care options like meals, room, pain management, physical therapy, and, most importantly, skilled surgeons, innovative technologies, and advanced surgical techniques. At Phyathai 2 Hospital, we have experienced orthopedic surgeons specializing in knee replacement, multidisciplinary teams, and the latest VELYS™ Robotic-Assisted Knee Replacement technology. This represents a new standard in knee surgery, ensuring patients can return to their daily activities without suffering from pain anymore.
What is VELYS™ Robotic-Assisted Knee Replacement (Generation 4)?
VELYS™ Robotic-Assisted Solutions (VRAS) is a tool used by orthopedic surgeons to assist in knee replacement surgeries, making the procedure more accurate, efficient, and faster. The latest Generation 4 version is compact and easy to move, giving surgeons flexibility in its use. The robot can be controlled precisely to ensure it moves as directed. The VELYS™ system features three key technological advancements:
3 Key Advantages of VELYS™ Robotic-Assisted Knee Replacement (Generation 4)
1. No need for a CT scan: This reduces radiation exposure, increasing patient safety while also shortening preparation time and the duration of surgery.
2. Advanced imaging and analysis technology: Using preoperative imaging, measurements taken during surgery, and the patient’s anatomical structure, the robot assists in planning to perform the procedure. The system provides real-time updates via a camera, helping the surgeon adjust the original knee joint, control tissue and ligament tension, and position the implant for the most optimal fit. This real-time data enhances surgical precision, leading to improved outcomes and potentially extending the longevity of the knee implant.
3. Precision and accuracy: The robot ensures the knee implant is positioned and locked within a precision range of 0.5 mm or 0.5 degrees. It also controls the movement of surgical tools and the implant to avoid misalignment, reducing damage to surrounding tissues, ligaments, and muscles. These results in quicker recovery, less pain, and faster rehabilitation compared to traditional methods, cutting down both recovery time and hospital costs.
Who is a Suitable Candidate for Robotic-Assisted Knee Replacement?
Robotic-assisted knee replacement is suitable not only for elderly patients suffering from age-related osteoarthritis or knee degeneration due to injury but also for those with rheumatoid arthritis or previous knee replacements that have failed due to implant damage or decreased function.
Preparing for Robotic-Assisted Knee Replacement Surgery
Before surgery, the patient’s anatomy (bones and soft tissues around the knee) will be assessed, and a detailed medical checkup will be done to minimize the risk of complications, especially if the patient has other underlying health conditions. Preparations also include addressing medication use (e.g., blood thinners), mental health counseling to reduce anxiety, and planning rehabilitation and physical therapy post-surgery, so patients are as prepared as possible.
Limitations of Robotic-Assisted Knee Replacement Surgery
While robotic-assisted surgery is highly advanced, it may not be suitable for all patients. It is typically not recommended for those with:
• Severe osteoarthritis or significant knee deformities.
• Substantial bone loss or osteoporosis.
• Infections in the knee joint or neurological/muscular conditions affecting the knee.
• Paralysis or severe weakness of the thigh muscles that would hinder recovery.
In cases where a patient cannot undergo robotic surgery, the surgeon will assess alternative treatment options. For patients with chronic conditions like heart disease, diabetes, or high blood pressure, those conditions must be controlled before surgery to ensure the patient’s safety and the best possible outcome.
Knee replacement surgery still offers a variety of techniques, tools, implant materials, and technologies to choose from. The orthopedic surgeon will guide the patient through the options to ensure the most appropriate treatment plan is selected, ensuring both health benefits and peace of mind. This process aims to ensure that patients are satisfied before, during, and after surgery, enabling them to return to an active lifestyle without obstacles.
