protesis_rodillaIt is a surgical procedure to replace the articular surfaces of the knee for an artificial surface. To coat the end of a worn femur, few cuts are made in the cartilage to place a metal component. Then, after making some appropriate cuts, a component with a metal part and one made of high density plastic (polyethylene) are placed in the tibia, and if required, a plastic button is placed in the patella. To achieve faster component fixation, bone cement (methylmethacrylate) is typically used to seal them in place.

 

There are several reasons for recommending knee replacement surgery:

  • The knee has bowed as a result of severe arthritis.

  • Severe pain or stiffness in the knee with limitation of daily activities, including walking, climbing stairs, sitting and rising from a chair, etc.

  • Moderate to severe pain knee while resting, day and night.

  • Chronic inflammation and swelling of the knee that does not improve with rest or medications.

  • Knee deformity.

  • No substantial improvement is experienced with other treatments such as anti-inflammatory medications, cortisone injections, lubricating injections, physical therapy or other surgeries.
