APPENZELL, Switzerland--(BUSINESS WIRE)--May 26, 2005--ReGen Biologics, AG, a wholly owned subsidiary of ReGen Biologics, Inc., (OTC:RGBI) an orthopedic products company that develops, manufactures and markets innovative tissue growth and repair products for U.S. and global markets, announced today that the company will be hosting an evening event during the EFORT Congress in Lisbon at 6:00 p.m. on June 6th 2005 for surgeons currently familiar with the ReGen(R) CMI or those who would like to obtain more information.

ReGen Biologics, AG is inviting all interested surgeons to participate. During this event, the CMI five (5) year follow-up data from the feasibility study will be presented. These data have been published as the lead article in the May 2005 issue of the peer-reviewed journal Arthroscopy. Clinical data including serial magnetic resonance imaging and arthroscopic examinations demonstrate the benefit of the CMI for these patients and provide evidence that a substantial amount of meniscus tissue is regained compared to a partial meniscectomy, which is the alternative treatment.

If you would like to attend this event, please R.S.V.P. to ReGen Biologics AG or contact one of the two European contacts below.
