Knee arthroplasty, more commonly known as knee replacement surgery, helps patients with severe knee pain and damage. Most often recommended as a treatment for patients with disabling arthritis, knee replacement usually is considered when other forms of therapy no longer suffice. Other considerations include the patient’s age and activity level, because a high degree of activity can reduce the longevity of the replacement. For this reason, most knee replacement patients tend to be older and more inclined to a sedentary lifestyle.

The procedure involves replacing damaged knee cartilage and bone with an artificial material. This can be a partial or a total replacement, depending on the type and degree of damage. After the procedure, hospital staff closely monitors the patient and provides pain control. Physical therapy begins while the patient is hospitalized.
