SKILLMAN, N.J., May 15, 2013 /PRNewswire/ --Preliminary findings from a new
prospective study of complications after knee replacement surgery show a 47
percent decrease in wound complications, such as skin blistering and prolonged
healing, when AQUACEL® Ag SURGICAL cover dressing was used, compared with
standard surgical dressing.

Patients in the study also reported significantly higher levels of
satisfaction with AQUACEL® Ag SURGICAL cover dressing versus standard dressing
in the areas of comfort, hygiene and mobility post surgery.

The preliminary results of the study, which was conducted at the OrthoCarolina
Hip and Knee Center with support from ConvaTec, were presented at the 2013
Annual Meeting of the American Academy of Orthopaedic Surgeons.

Also presented during the meeting were final results of a large retrospective
study of infections following knee and hip replacement surgery, also supported
by ConvaTec. These results, of 1,778 patients, showed AQUACEL® Ag SURGICAL
cover dressing reduced the incidence of joint infections by 76 percent,
compared with standard gauze dressing.

"Reducing hospital-acquired infections and increasing patient satisfaction
have become critically important in light of the new healthcare law in the
U.S., which links hospital reimbursement rates to these measures," said Bryan
D. Springer, MD, Fellowship Director, OrthoCarolina Hip and Knee Center, and
author of the study. "These studies confirm that AQUACEL Ag SURGICAL can have
a direct impact on these measures."

More than one million knee and hip replacement surgeries are performed
annually in the U.S. Wound complications following these surgeries are
common. These complications increase the risk of patients developing surgical
site infections, which can be dangerous and expensive—they can drive up
treatment costs $60,000 to $100,000 and extend hospital stays seven to 10
days—and often result in the need for additional surgery. A study published
last year in the Journal of Arthroplasty estimated the annual cost of infected
revision surgeries to U.S. hospitals at $566 million in 2009, and projected to
exceed $1.62 billion by 2020.

"Complications following joint surgery can be physically and mentally
devastating for patients, as well as costly for healthcare facilities. As the
results of these studies indicate, the use of AQUACEL® Ag SURGICAL cover
dressing can make a significant difference in reducing these complications,
including surgical site infections, and improving patient satisfaction," Dr.
Springer concluded.

About the Study
In the first of a two-part prospective study conducted at the OrthoCarolina
Hip and Knee Center, 150 knee replacement patients were randomly selected to
receive either the advanced antimicrobial surgical dressing or a standard
gauze and tape surgical dressing following surgery. Standard protocols were
followed for wound closure and dressing changes. Preliminary results showed
that 43 percent of patients with the standard dressing developed wound
complications, compared with only 23 percent of patients with the AQUACEL® Ag
SURGICAL cover dressing. Patients in the study were asked to rate their
perceptions of the dressings in relation to their personal hygiene and
activities of daily living after surgery. On measures such as the ability to
shower, change clothes, sit and sleep comfortably, patient satisfaction
ratings for AQUACEL® Ag SURGICAL cover dressing were higher than for the
standard dressing.

Results from the second of the two-part study focusing on 150 patients
following hip replacement surgery will be presented at upcoming meetings.

About AQUACEL® Ag SURGICAL Cover Dressing
AQUACEL® Ag SURGICAL cover dressing combines a proprietary Hydrofiber®
Technology wound contact layer with the skin-like flexibility of DuoDerm™
Technology. The advanced antimicrobial cover dressing is designed to protect
surgical incisions with a waterproof viral and bacterial barrier that also
allows for greater range of motion and comfort after surgery.

About AQUACEL® Dressings with Hydrofiber^® Technology
AQUACEL® dressings with Hydrofiber® Technology, exclusively from ConvaTec, gel
on contact with wound exudate, providing clinicians and patients with
substantial wound care benefits. As demonstrated in vitro, this unique
gelling action locks in exudate and harmful bacteria and micro-contours to a
simulated wound bed, minimizing "dead space" where bacteria can thrive.

AQUACEL® Ag dressings with ionic silver provide rapid, effective and sustained
antimicrobial activity. As demonstrated in vitro, AQUACEL® Ag dressings kill
a broad spectrum of pathogens, including methicillin-resistant Staphylococcus
aureus (MRSA) and vancomycin-resistant enterococci (VRE), within 30 minutes of
exposure to the dressing, for up to seven days.
