Knee replacement surgery involves the removal and replacement of damaged bone and cartilage around your knee joint with prosthetics. During surgery, the bone is prepared for the placement of these prosthetics, the prosthetics are positioned and placed, and a spacer is placed between the prosthetic components to enable a normal gliding motion. In some cases, the undersurface of your kneecap is also resurfaced with a plastic button.
You may receive either a total or partial knee replacement surgery. A total knee replacement surgery involves capping the ends of the knee joint bones and kneecap with plastic or metal prosthetics. A partial knee replacement removes injured tissue and bone only from certain areas of the joint, replacing these parts with prosthetics and preserving more natural tissue. Which procedure you’re recommended for will depend on the severity of your symptoms and your medical history.
At Orthopedic Specialists of New York, knee replacement surgeries are also performed using Mako, a robotic surgical assistant that helps our doctors conduct your procedure more effectively. Mako allows a surgeon to plan your procedure with a detailed 3D model. Its robotic arm also assists your surgeon’s precision, reducing the amount of cutting required to complete your surgery and preserving more of your healthy bone.
