Hip Implant Recalls
A recall does not necessarily mean that a particular implant needs to be removed and replaced, but as the FDA explains, it may mean “different or more frequent monitoring” for patients who have used the device or have had it implanted.
There have been recalls of hip replacements devices due to component failures. Although the Zimmer ProxiLock Hip Prosthesis has not been recalled, Zimmer has discontinued manufacturing the device, according to the Watts et al. study. 1
Hip implants may be recalled for a variety of reasons. A recall does not necessarily mean that a particular implant needs to be removed and replaced, but as the FDA explains, it may mean “different or more frequent monitoring” for patients who have used the device or have had it implanted.
Some recalls of defective implants are:
Stryker: In November 2014, Stryker agreed to pay $1.43 billion or more to settle thousands of lawsuits from individuals who had to have revision surgeries to remove two types of recalled Stryker hip implants. Plaintiffs claimed Stryker’s Rejuvenate Modular-Neck and ABG II Modular-Neck hip implants became corroded, among other problems. In July 2012, Stryker had recalled both of these hip replacement systems, acknowledging the “potential risks associated with fretting and corrosion.” 4 5 11
Smith & Nephew: On June 1, 2012, Smith & Nephew Orthopaedics voluntarily withdrew from the market the metal liners of its R3 acetabular system. These liners were linked to a higher than expected rate of revision surgeries outside of the U.S.
DePuy: On August 24, 2010, DePuy recalled its ASRTM total hip system. According to national joint registry data in the United Kingdom, this hip replacement system was linked to a higher-than-expected rate of revision surgeries. In January 2013, DePuy also recalled its Adept all-metal total hip replacement system, once again because of a higher than expected number of revision surgeries.
Zimmer: On July 22, 2008, Zimmer voluntarily recalled its Durom® Acetabular Component (“Durom Cup”). The recall indicated that its “instructions for use/surgical technique instructions were inadequate.”

FDA Metal-on-Metal Hip Implant Information
In February 2011, the FDA posted metal-on-metal hip implant information online. This allows the FDA to provide updated safety information, as well as recommendations to patients and health care providers.
The stem sections of most hip implants, which are inserted into the thighbone to anchor the ball of the implant, are made of metal, either titanium- or cobalt/chromium-based alloys. The ball of the prosthesis is made of either metal or ceramic.6 7
Metal-on-metal systems include a ball, stem and shell. Each part is made of some combination of metals. 8
Number of Hip Replacement Surgeries Is Rising
According to U.S. News & World Report and NBC News, the number of hip replacement surgeries is rising, particularly among people 40 to 60 years old, but also among young adults in their 20s and 30s. 9 10
