Knee Replacement (Knee Arthroplasty)

see also Partial Knee Replacement/Resurfacing (Unicondylar Knee Replacement)

Most knee replacements attempt to mimic the normal motion of the knee, which can bend and straighten over one hundred times a minute while walking. Though something as common as the act of walking is easy for most, for those with advanced arthritis, such repetitive motion on an already weakened joint can be quite painful and require tireless effort. Often, knee replacement is the only option to alleviate the pain.

The ability to walk easily depends upon the intricate working of the knee joint, the largest joint in the body. The knee is formed by the junction of three bones: the femur (the thigh bone), the tibia (the shin bone), and the patella (the kneecap). These bones are connected to each other by strong ligaments. The powerful muscles of the thigh and calf attach to the bones around the knee by means of inelastic ligaments.

Peter Sgambati was diagnosed with arthritis in his knee. He underwent knee replacement surgery, but had to have his implant removed twice after infections set in. He turned to the doctors at HSS to alleviate the pain his arthritis and previous knee replacements were causing him. In this video, Mr. Sgambati tells his story.
