When the Stryker Rejuvenate hip implant was introduced it was considered quite innovative in design; the Rejuvenate was marketed in 2009 after gaining FDA approval in June, 2008. While traditional hip implant designs were manufactured with a one piece neck and stem, both the Rejuvenate and ABGII have a design which implements a variety of components. In fact, the ABGII hip implant has sixteen stems—including left and right sides, and ten different sizes of modular neck. Six stems and sixteen necks make up the Rejuvenate hip implant system. Marketing for the Rejuvenate claimed that this hip implant was designed specifically for the younger, more active patient who was currently experiencing limited mobility of their hip joint.

Metal on metal hips have been distributed in the United States for many years now, but recent information has revealed that many hip implant recipients may be mistaken as to what specific hip replacement device they were implanted with.

The Stryker Orthopedics design for the Rejuvenate was considered quite innovative when it was introduced in 2009 after being FDA approved in June of 2008. Conventional hip implants have a one piece neck and stem while the Rejuvenate and ABGII hip implants are made up of several components. The ABGII hip implant system has sixteen left and right stems and ten modular necks.

Even though the flaws with the metal-on-metal hip implants have been widely publicized, there are still likely thousands of recipients of the device who have no idea they potentially have a veritable ticking time bomb inside their bodies. The Stryker ABGII and the Stryker Rejuvenate have been recalled after an Urgent Product Safety Bulletin was sent out to doctors and hospitals advising them of the excessive metal debris and ion generation possible from these two hip implants.
