New Minimally Invasive Device Uses Radiofrequency Energy to Smooth Cartilage in Weight-Bearing Joints

Proprietary pivoting head targets damaged cartilage cells ANDOVER,
Mass., Dec. 1 /PRNewswire-FirstCall/ -- Smith & Nephew's (NYSE:
SNN)(LSE:SN) Endoscopy division today launched the GLIDER(TM)
Articular Cartilage Probe, a minimally invasive device for treating
articular cartilage disease, during the Arthroscopy Association of
North America's (AANA) Fall Course in Phoenix. Articular cartilage
disease is a natural effect of aging, sometimes exacerbated by
sports injury, and is considered a precursor to osteoarthritis.
Friction from years of use, and sometimes trauma, can roughen the
surface of the cartilage in weight-bearing joints, such as the knee
or the hip, causing pain when the bones move against one another.
For example, cartilage fragments can cause the knee to "catch" or
"pop" as it is bent. Each year, surgeons in the United States
perform an estimated 600,000 knee arthroscopies to treat the
effects of articular cartilage disease. The GLIDER(TM) probe's
proprietary design features a pivoting head that emits
radiofrequency (RF) energy as it follows the contoured surfaces of
the joint. Through controlled application of energy, it restores
smoothness to a damaged cartilage surface while preserving the
maximum amount of healthy tissue. Supporting the pivoting head is a
flexible framework, which operates as a sort of shock absorber,
allowing the electrode in the pivoting head to maintain consistent
contact along the cartilage surface. This wire frame also makes it
possible for the probe to reach parts of the joint surface that
probes with rigid designs cannot access. "Smith & Nephew's
GLIDER(TM) Articular Cartilage Probe is effective in smoothing the
roughened cartilage of the knee," said Dr. Philip A. Davidson of
Tampa Bay Orthopedic Specialists in Tampa Bay, Florida. "It is a
significant advancement in the treatment of articular cartilage
disease." "Articular cartilage disease is a common disorder, and if
we can treat patients early, then we might possibly delay more
invasive treatment," said Dr. James H. Lubowitz, founder and
director of the Taos Orthopaedic Institute in Taos, New Mexico, who
worked with a team from Smith & Nephew Endoscopy to develop the
device. "Early treatment is important, because the further that
joint lining degeneration is allowed to progress, the more complex
are the procedures required to treat it." "Articular cartilage
disease affects active people young and old," said Jerry Goodman,
vice president and general manager of Smith & Nephew
Endoscopy's Resection business. "The GLIDER Articular Cartilage
Probe provides a minimally invasive way to treat its effects, which
helps get people back on their feet." Preserving healthy cartilage
The challenge in developing the GLIDER Articular Cartilage Probe
was finding a way to effectively smooth diseased tissue, while
preserving surrounding healthy tissue. Lubowitz and the Endoscopy
team conducted a study of how factors such as probe design and
generator power settings, as well as speed and force of application
affect the procedure. The study showed that those design features
could be optimized to ensure retention of the maximum amount of
healthy cartilage. Their research earned the Richard C. O'Connor
Award, the highest award bestowed by AANA at the group's 2005
spring meeting in Vancouver, British Columbia. About Smith &
