Knee replacement surgery good for 20 years
By Shari Roan, Los Angeles Times
Knee replacement surgery has become common in the last 30 years, and more younger people with bad knees are considering the surgery. A study presented last month at the American Academy of Orthopaedic Surgeons annual meeting may reassure them that the replacement should hold up for a long time.
Researchers evaluated 128 people who had lived at least 20 years after total knee replacement surgery. The patients’ average age at the time of surgery was 63. The average age at the post-20-year follow-up was 82. The study found that almost all of the patients had good physical function. Most could walk at least five blocks, and half said they had “unlimited” walking ability. All but two could walk up and down stairs. None of the patients had experienced an implant failure.
My Mom, who is 80 years old, had both knees replaced last year with Stryker implants because of bone-on-bone arthritis. She gained about 3 inches in height by being able to stand up straighter. She is actually able to walk short distances and is thrilled with the outcome.
It is amazing what can be done with knee, hip, shoulder and elbow implants. The technology has given back mobility to many who would otherwise be relagated to the sofa.
