Did you receive a metal-on-metal hip replacement? If so, you may be among the thousands of patients now dealing with the serious side effects – including revision surgery to replace a defective device – linked to metal-on-metal hips. Victims suffering from complications associated with metal-on-metal hip replacements may be entitled to compensation for their medical bills, pain and suffering, lost wages, and other damages. In an effort to educate consumers, Sokolove Law has compiled important information regarding the following hip replacement topics:

Serious Problems with Hip Replacement Implants
Hip replacement implants are medical devices meant to ease pain and restore mobility lost to age, injuries, or disease. Each year some 250,000 hip replacements are performed in the U.S. and about one-third of these procedures have used a metal-on-metal implant.
Metal-on-metal or MoM hips were marketed as more durable and longer lasting than other hip replacement devices constructed of plastic or ceramic. MoM hip devices consist of a ball, stem, and shell made of metals such as cobalt or chromium.
All hip devices shed particles as the ball rubs and rolls within the socket. But when this action occurs in certain MoM hips, tiny metallic particles are released and absorbed into nearby tissues and blood. This can trigger devastating side effects in patients including:
- Bone loss
- Death of tissue in and around the hip joint
- Loss of mobility
- Pain in the groin
- Severe inflammatory reactions
Subsequent studies of hip replacement implants have also raised concern about loosening, high failure rates for various devices, and the need for painful revision surgery to remove and replace a potentially defective implant.
Hip Replacement Recalls
There have been several recalls or withdrawals of MoM hip systems or components in the U.S. in recent years.
In August 2016, Stryker Corporation recalled several lots of its LFIT™ Anatomic CoCr V40 Femoral Head, a component in many MoM hip replacements. According to Stryker, the company has received higher than expected complaints of taper lock failure with certain lots made before 2011.
There are a number of potential complications associated with the issue, including excessive metallic debris, component fracturing or disassociation, and insufficient range of motion, among other problems. These complications may cause serious side effects, including, but not limited to: pain, loss of mobility, inflammation, adverse local tissue reaction, and metallosis. These side effects often require revision surgery to correct the issue(s).
Prior to Stryker recalling the LFIT V40 Femoral Head, Smith & Nephew Orthopaedics withdrew the metal liners for its R3 acetabular hip system in 2012 due to a high rate of revision surgeries associated with its use in total hip replacements outside the U.S. Also in 2012, Stryker voluntarily recalled its Rejuvenate and ABG II modular-neck stems – a component of metal-on-metal hip implants – for possible fretting or corrosion on or about the modular-neck junction, which could cause swelling or pain.
In 2010, Johnson & Johnson’s DePuy Orthopedics recalled its Hip Resurfacing System after clinical studies revealed high rates of failure and adverse reactions.
And in 2008 Zimmer Inc. issued a voluntary recall of its “Durom Cup” acetabular component due to inadequate instructions regarding use and surgical technique.
