What is the average age for a total knee replacement?
Most people who undergo a knee replacement are between the ages of 50 and 80. The average age is about 70. About 60 percent of the recipients are women. The procedure has a high success rate and is considered relatively safe and effective.
When knee replacement procedures were first performed in the early 1970s, it was thought that the average total knee implant would last approximately 10 years. We now know that approximately 85 percent of the knee implants will last 20 years.
- After preparing the joint surfaces, the surgeon attaches the pieces of the artificial joint. Before closing the incision, he or she bends and rotates your knee, testing it to ensure proper function. The surgery lasts about two hours.
- Minimally-invasive quadriceps-sparing total knee replacement is a new surgical technique that allows surgeons to insert the same time-tested reliable knee replacement implants through a shorter incision using surgical approach that avoids trauma to the quadriceps muscle (see figure 1) which is the most important muscle
- The metals used in artificial knees are alloys of cobalt-chromium and titanium. The bearing portion of the joint is made of a high-grade, wear-resistant plastic. The metal-plastic bearing combination is the most common type used in knee replacement implants worldwide.
