The first total knee replacement was performed in 1968. The procedure is one of the most important orthopedic surgical advances of the 20th century. Every year in the United States alone, more than 300,000 knee replacements are performed. The number of total knee replacements is expected to increase 525% by the year 2030, according to the March 6, 2008 issue of Time.

It's essential for an arthritis patient considering knee replacement surgery to understand what to expect from the procedure. It's important to understand:

• the ultimate goal of having the surgery which for most patients is pain relief and improved knee function
• knee replacement surgery does not turn you into the Bionic Man or Woman with super powers
• you will have certain restrictions after surgery, some being temporary until you have healed and some for the rest of your life knee replacements last many years but may need revision surgery when they wear out or loosen

The majority of knee replacement patients -- upwards of 90% -- have a successful outcome following surgery. Patients typically report dramatic pain relief, and the ability to do daily tasks they have not done easily for a long time. Even so, there are recommendations for activity levels after surgery.
