ReGen Biologics Participates in 2007 AANA Annual Meeting

ReGen Biologics (OTC: RGBI) will exhibit the company's products at
the Arthroscopy Association of North America (AANA) meeting, being
held this week in San Francisco.

Additionally, data from its CMI(TM) product clinical trial will be
highlighted in two podium presentations and two "e-posters" as part of
the scientific program offered to attending surgeons.

The first presentation focuses on the correlation between tissue
loss and clinical symptoms, function and activity levels following
meniscectomy. The second underscores the decreased rate of
re-operations for chronic patients receiving a collagen meniscus
implant. Both presentations are scheduled for this afternoon.

The e-posters are available for review throughout the meeting. One
features the latest suture techniques being used for fixation of the
collagen meniscus implant and the other documents new tissue growth
and increased activity level in patients two years following a
collagen meniscus implant procedure.

"The AANA meeting provides an excellent forum for ReGen management
and clinical collaborators to meet and discuss our latest clinical
data," said Gerald E. Bisbee, Jr., Ph.D., Chairman and Chief Executive
Officer of ReGen Biologics.

Copies of presentation and poster abstracts will be available on
the ReGen corporate website following the completion of the AANA
annual meeting at www.regenbio.com.

The stated goal of the AANA is to promote, encourage, support and
foster through continuing medical education functions, the development
and dissemination of knowledge in the discipline of arthroscopic
surgery. For more information on the annual meeting, or scheduled
