  • Knee Replacement Surgery

  • In total knee replacement surgery, the parts of the bones that rub together are resurfaced with metal and plastic implants. Using special, precision instruments, your surgeon will typically remove the damaged surfaces of all three bones. The replacement surfaces will then be fixed into place.

    The surface of the femur is replaced with a rounded metal component that comes very close to matching the curve of your natural bone. The surface of the tibia is replaced with a flat metal component that holds a smooth plastic piece made of ultra-high-molecular-weight polyethylene plastic that serves as the cartilage.

    The undersurface of the kneecap may also be replaced with an implant made of the same polyethylene plastic.

    The success of knee replacement surgery depends on the precise positioning of both the femur and tibia implants relative to the anatomy. Improper positioning can lead to pain and complications that can lead to additional surgery, or premature wear of the implants. After successful knee replacement surgery, it is likely that the patient will recover much of the normal range of motion of the knee, from extension (straight leg) to flexion (bent leg).
