Unicompartmental Knee Replacement

Knee replacement surgery is not uncommon. Hundreds of thousands are performed each year with the goal of reducing pain and restoring joint function for patients. Unicompartmental "Partial" knee replacement surgery is now available for select patients at St. Joseph's . The hospital recently acquired the Navio™ Surgical System, which is a robotic- assisted orthopedic system.

Navio provides surgeons with a hand-held, computer-assisted bone cutting tool, which is precisely guided with the robot's navigation system. The system uses a smaller, minimally invasive incision which allows the surgeon to treat either side of the knee.

Computer or Robotic-Assisted Surgery Advancements in Orthopedics

Technological advancements have led to the introduction of robotic-assisted surgery in orthopedics. “The use of robotics in knee replacement surgery is still relatively new, and requires a knowledgeable surgeon with experience in the traditional open surgery methods as well,” says Dr. Seth Greenky.

Surgeons use computer mapping in conjunction with a robotic arm to resurface the diseased portion of the knee joint and insert the implant. According to Dr. Greenky, “Robotic-assisted surgery can improve accuracy and placement of the implant and provides a certain level of predictability in outcomes for the surgeon and patient. As orthopedic surgeons, it is our hope that in time, this increased accuracy will work to extend the longevity of the prosthesis used in partial knee replacements.”

Is Partial Knee Replacement an Option for You?

Its recommend that anyone experiencing knee pain make an appointment with their primary care physician for thorough evaluation. “The primary care physician is the first step to diagnosing the condition. The primary care physician will work with the patient to be certain that all non-surgical options have been investigated,” says Seth. “Following that evaluation the physician may make a referral to an orthopedic surgeon to further evaluation of conservative or surgical treatment options.”
