In the News: Wounded Knees: Dr. Zelicof on News 12 Long Island

Part 2: Total Knee Replacement Surgery as performed by Dr. Zelicof

Dr. Steven Zelifof

After years of dealing with painful, arthritic knees, Miriam Rios and her doctors agreed: it was time of arthritic knee surgery.

Orthopaedic surgeon Steven Zelicof and his team at Sound Shore Medical Center will perform the operation with the help of the Stryker Navigation System: a computer that guides surgeons through the operation.

First a tourniquet is applied to minimize blood loss. The leg is then placed in a movable track. Doctors will use this to check movement throughout the surgery. An incision is made to get inside the knee. Muscle and the knee cap are moved to get to the femur, or thigh bone.

Doctors attach several probes to the bone through an infrared device that sends information to the computer. The computer marks the arthritis in the bones and even gives directions.

“This is telling us – really, within a degree or two – exactly where our position wants to be. It really is like a GPS. [With this machine,] you can see how worn out these areas are.”

Using a saw, the end of the femur, or thighbone, is removed. Next comes the end of the tibia, or shinbone. Cuts are made and holes drilled into the bones, where the prosthesis will lock in. But doctors first try the test part to make sure it all fits.

Dr. Zelicof then prepares actual cement that will keep the prosthesis in place. The cement is poured into the grooves of the bones, created by the team. And then the replacement knee is locked in. And with that, Miriam’s new knee, made of cobalt, chrome, titanium and plastic is in place.
