Excitement was in the air as Watauga Medical Center staff gathered around the loading dock in hopes of witnessing history. At last, the long-awaited day had come, “it” was here. The crowd cheered as a medical transport truck unloaded a new high-tech piece of equipment, the first robot-assisted surgery system in the High Country.
Moments later the machine was ushered into the materials management department where it was quickly assembled and brought to life for the first time. As with all new medical equipment, the robot was then carefully inspected before it was transported to its new home in the operating room.
This new cutting-edge robot is the latest example of Appalachian Regional Healthcare System’s unwavering commitment to provide the best in advanced surgery technology right here in the High Country.
Bells & Whistles
Although conventional knee replacements have become highly successful over the years, research indicates that 10-30 percent of patients remain dissatisfied post-surgery.1-5
Just like an automobile in an assembly line, each part must be put in exactly the right place in order for the vehicle to function properly and to avoid a costly recall. Orthopedic surgeons work in the same way to reduce variation when performing surgery. In other words, improving patient outcomes is dependent upon establishing reproducible results, decreasing complications and reducing readmissions to the hospital.6
That’s where the power of robotics comes in to help. Surgeons will use the new robot-assisted surgical system to aid in component positioning, ligament balancing and bone preparation – key factors that can drive implant survivorship.7-8
How It Works
The surgeon uses the robot in the operating room to create a 3D model of the patient’s cartilage and bone through direct surface mapping. Direct surface mapping saves the patient time, money and unnecessary exposure to radiation by eliminating the need for a conventional preoperative CT scan. The surgeon then uses the 3D model to virtually simulate the knee replacement on the robot’s large screen monitor before starting the actual procedure.
The surgeon then uses the handheld robot’s burring technology to accurately assist in bone removal and preparation. From there, the robot is used to help implant the knee replacement device. This entire process is displayed on the monitor in real-time, allowing the surgeon to continually assess the patient’s anatomy against the simulated operative plan.
Some patients will benefit from the JOURNEY™ II XR (bi-cruciate retaining total knee system implant) which is one of the only total knee designs allowing retention of the ACL, and is designed to improve patient satisfaction.10 Determining which implant option is best for the patient is a patient-specific decision made with guidance from the surgeon.
Most knee replacement patients require a brief inpatient stay at the hospital. To better care for these patients, Watauga Medical Center recently opened a new 10-bed orthopedic wing on the third floor of the hospital. Designed with the patient in mind, the new wing serves as a safe environment for patients to recover and to start the rehabilitation process. The wing is staffed by a dedicated team of specialty trained nurses, physical and occupational therapists and medical providers from AppOrtho.
Compared with conventional methods, robot-assisted knee replacement procedures typically result in increased accuracy of alignment, decreased pain, improved early functional recovery and reduced time to hospital discharge.11-12
The first robot-assisted knee replacement surgery at Watauga Medical Center is scheduled for later this week.
“We used to talk a lot about how patients would have to travel down the mountain for state-of-the-art orthopedic care,” said Eddy Maillot, Senior Director of Clinical Services at Appalachian Regional Healthcare System. “I’m proud to report that we have noticed, for some time a trend in which patients are choosing to travel up the mountain for their advanced orthopedic procedures. At AppOrtho, great doctors provide the best care to our patients, as well as the best in surgical technology.”
Not every patient is a good candidate for a robot-assisted knee replacement surgery. At AppOrtho, each patient is carefully evaluated in order to determine the most appropriate treatment option. All non-surgical treatment options are considered before surgery is recommended.
