What are Hip & Knee Implants and How Do They Work?
Hip or knee replacement is done to replace an injured or malfunctioning hip or knee joint that is causing pain, inflammation, and immobility to the patient. Artificial implants then replace the damaged areas to mimic normal motion.
Hip replacement surgery is usually done for patients with hip joint arthritis. The surgeon first removes the ball portion of the thigh bone and damaged cartilage from the surface of the hip bone. A ball -and-joint implant is then inserted and kept in place using medical glue or cement to replace the damaged portions.
Knee replacement surgery follows the same approach, with damaged bone and cartilage removed. In this case, the lower end of the thigh bone, the top surface of the leg bone, and the back surface of the kneecap are involved in the procedure.

Risks and Complications
Metal-on-metal implants are very durable. They have less wear and can withstand a more active lifestyle. However, durability comes at a price. Metal-on-metal implants can shed metal particles that may cause a number of serious health issues, including
Metallosis occurs when metal ions from abrasion of the metal surfaces accumulate into the blood and tissues. This results in metal poisoning, causing damage to the surrounding tissues, bones, and even the nervous system.
Metal hip implants, in particular, can result in cobalt poisoning, where excess levels of cobalt in the blood cause neurological complications, heart and lung problems, and hypothyroidism.
Other risks and complications of metal on metal implants include:
- Premature failure of the implant
- Additional surgeries
- Pain and inflammation
- Instability and dislocation
- Nerve Injury
In December 2017, the FDA posted information about the concerns in using metal-on-metal hip implants. It discussed the dangers of metal ions entering the bloodstream and the symptoms of a malfunctioning device. They also cited alerts and safety communications from international regulatory agencies in the UK, Canada, and Australia regarding the medical devices, in addition to data from scientific communities.
Between 2002 and 2013, Consumers Union identified six manufacturers that recalled metal on metal hip implants:
|Manufacturer||Number of recalled units||Reason for recall|
|Zimmer||104||Labeling, manufacturing, packaging, fit, instruction issues; fracturing, missing components, metal grain structure anomaly|
|Stryker||231||Fracturing, cracking, labeling, manufacturing, packaging issues,|
|Smith & Nephew||40||Incorrect parts/ instructions, manufacturing issues, design flaws, labeling issues|
|Wright||28||Labeling, packaging, manufacturing issues;
|150||Labeling problems, design flaw, high failure rate, early failure, packaging, migration, and manufacturing issues|
|Biomet||25||Labeling and fracturing issues|
FDA classified more than 10% of these recalls under Class 1, meaning there is
Hundreds of knee implants from some of these manufacturers were also recalled over the years due to associated complications. Zimmer’s NexGen Knee Replacement Systems faced a Class 2 recall from FDA in 2010 due to potential fracturing of the device’s components, affecting over 68,000 devices already implanted.
In 2015, the company then voluntarily recalled a component of its knee replacement system, Persona Trabecular Metal Tibial Plate, due to complaints of loose plate fit.
Collectively, manufacturers Zimmer, Depuy, Stryker, Smith & Nephew, and Wright Medical recalled over a thousand knee implant system and component units from 2003 to 2018.

Injuries from Hip & Knee Implants
A study published in 2017 by the BMC Psychiatry found out that neurocognitive and depressive deficits were present after metal on metal implant failure. It followed 10 patients who received hip implants from 2005 to
A 2012 study published in The Lancet showed that failure rates in metal on metal total hip replacements are high compared to ceramic implants. The study included 31,171 patients fitted with stemmed metal on metal hip implants between 2003 and 2011. Five-year revision rates for older men ranged from 3.2% to 5.1%, and 6.1% for younger women. In contrast, ceramic on ceramic implants only had 2% to 3.3% revision rates for older
Moreover, another study in 2012 identified the reason for
