Knee Replacement Surgery Is 'Durable, Reliable, and Successful'

In terms of available implants, "in straightforward cases, the choice of
one design over another is largely a matter of surgeon preference," they
After reviewing several studies on the outcomes of knee replacements, the
authors find "excellent long-term success" with most of the studies
showing well over 90% survivorship at periods ranging from 10 to 16 years and
annual failure rates significantly under 1%.
Newer implants include "cementless" implants, which show promising
results and may become particularly beneficial for younger patients. A lot of
research is now being directed at improving these implants for younger, more
active patients, the authors report.
The new findings also bring good news for younger people with severe knee
arthritis who may need replacement surgery, Spitzer says. "The younger
arthritic patient (aged 55 or under) has traditionally represented a
frustrating dilemma for the knee surgeon, but recent literature supports the
decision to proceed with arthroplasty when end-stage disease is
identified," the authors report.
"This new article really tells us where things are at in the world of
knee replacement," Ronald P. Grelsamer, MD, chief of hip and knee surgery
at Maimonides Medical Center in Brooklyn and an attending orthopaedic surgeon
at the Hospital for Joint Diseases in New York, tells WebMD. "There are a
number of available knee implants with reasonable track records, and my advice
is to go to a surgeon who uses an implant that has been around for a long time
as those are the ones with the most evidence supporting their use."
- For patients with severe knee arthritis, orthopaedic surgeons have made
great advances in total knee replacement surgery, with an annual failure rate
significantly less than 1%.
- The surgery involves resurfacing the kneecap and putting in an implant made
of steel and plastic.
- Researchers report that procedure can even be recommended for younger
patients with severe knee arthritis, a group to which physicians are sometimes
hesitant to advise surgery.
