A sensor-assisted knee replacement is a total knee replacement using a single-use, computerized spacer device to ensure artificial knee components are correctly balanced with soft tissues — ligaments, tendons and muscles — in the knee. The goal of sensor-assisted knee replacement is to allow you to bend your knee with ease and perform activities without pain and stiffness.
At Dignity Health - St. Rose Dominican, our surgeons offer a range of knee surgery options, including sensor-assisted knee replacement, in Las Vegas and Henderson, NV. Our Siena Campus earned a Joint Commission Certification for our knee replacement program. Call 702.616.4900 or use our online tool to Find a Doctor today.
Using a sensor during surgery helps your doctor properly balance the soft tissues of your knee with the artificial components. The sensor helps avoid making the new joint too tight, which would limit your range of motion, or too loose, which can cause instability.
Orthopedic surgeons perform total knee replacements, including sensor-assisted ones, in a Dignity Health - St. Rose Dominican hospital. Using a sensor does not change the type of implant your doctor can use or the surgical method. The surgery can be an open or a minimally invasive arthroscopic procedure. In either case, you will have general anesthesia.
The trial sensor lies between the femoral and tibia implants. It relays the soft tissue load on the implants to a computer. The surgeon uses the data to balance the soft tissue load and ensure the desired range of motion before removing the sensor and completing the operation.
The length of your hospital stay depends on the type of surgery you have. It may also be necessary to stay in a rehabilitation center before returning home. At home, you will need help with daily activities for a period of time. You will also need physical therapy, which is an essential part of recovery. It will help you regain knee function with less pain. Sensor-assisted knee replacement may help you recover faster.
Most people return to their favorite activities with very few limitations. Most artificial knees still function well 15 years after surgery. You can help prolong the life of your artificial knee by maintaining a healthy weight. People who are overweight have a higher rate of joint failure. You should also get regular exercise to strengthen and stabilize your knee and take care to avoid falls.
