===Hip replacement failure===
[[Hip replacement]] implants can fail. Outcomes are normally recorded in a [[joint replacement registry]] to ensure patterns are picked
In 2013 [[Johnson & Johnson]] shared documents which indicated that 40% of a class of hip replacement implants which it manufactured had failed.<ref>{{cite news |url= https://www.nytimes.com/2013/01/23/business/jj-study-suggested-hip-device-could-fail-in-thousands-more.html

===Cochlear implant failure===
Cochlear implants are used to treat severe to profound hearing loss by electrically stimulating the hearing nerve. Clinical symptoms of cochlear implant failure include auditory symptoms (tinnitus, buzzing, roaring, popping sounds), non-auditory symptoms (pain, shocking sensation, burning sensation, facial stimulation, itching), and decrease in the patient's hearing performance.<ref>{{cite journal |pmid=16015190 | volume=26 | title=Cochlear implant soft failures consensus development conference statement | year=2005 | journal=Otol.

===Dental implant failure===
{{Main|Dental implant failure}}
Failure of a dental implant is often related to the failure of the implant to osseointegrate correctly with the bone, or vice versa.
A dental implant is considered to be a failure if it is lost, mobile or shows peri-implant (around the implant) bone loss of greater than 1.0 mm in the first year and greater than 0.2 mm a year after.<ref>Tissue-integrated prostheses :osseointegration in clinical dentistry, Per-Ingavar Branemark, George A. Zarb, Tomas Albrektsson, 1985</ref> Dental implant failures have been studied.<ref>{{Cite journal | last1 = Moy | first1 = P.

==Responses to implant failure==
In 2012 [[Royal College of Surgeons of England]] and the [[British Orthopaedic Association]] called for increased regulation of implants to prevent implant failure.<ref>{{cite news |url= https://www.telegraph.co.uk/health/healthnews/9631974/Faulty-medical-implants-investigation-Patients-failed-by-poor-implant-regulation-say-surgeons.html |archive-url= https://web.archive.org/web/20121025092558/http://www.telegraph.co.uk/health/healthnews/9631974/Faulty-medical-implants-investigation-Patients-failed-by-poor-implant-regulation-say-surgeons.html |url-status= dead |archive-date= 25 October 2012 |title=Faulty medical implants investigation: Patients failed by poor implant regulation, say surgeons - Telegraph |first1=Holly |last1=Watt |first2=Claire |last2=Newell |work=[[The Daily Telegraph]] |date=24 Oct 2012
A 2011 study by Dr. [[Diana Zuckerman]] and Paul Brown of the [[National Research Center for Women and Families]], and Dr. Steven Nissen of the Cleveland Clinic, published in the Archives of Internal Medicine, showed that most medical devices recalled in the last five years for
