Hip & Knee Replacements
Were you looking for DePuy Canada or DePuy ASR Hip or DePuy Pinnacle or Zimmer Durom Cup or Zimmer NexGen lawsuits?
The past decade has seen an exponential increase in hip and knee replacements and with it, hip & knee replacement failure. With more and more baby boomers approaching an older age, hip and knee replacement surgery is becoming more common--as are hip and knee replacement complaints. Since the Depuy hip and knee replacement recalls in 2005, thousands of patients have filed a hip replacement lawsuit or a knee replacement lawsuit, claiming the medical devices are defective.

Increasingly, patients are receiving more hip and knee replacement surgeries, with about 600,000 knee replacement procedures alone performed in the US annually. Combined with a growing and worrisome number of knee replacements in younger people, both medical and legal experts predict that the amount of hip and knee failures may cost US taxpayers, insurers and employers billions of dollars in the coming years, according to The International Herald Tribune (December 2011).
Hip and Knee Replacements
Because hip and knee replacements represent an entire class of products rather than simply one device or one manufacturer (see list below), the financial repercussions stemming from hip and knee implants that are alleged to be defective will likely be enormous, especially when revision surgery is taken into account.
Given the amount of hip and knee replacement surgeries performed, there has been an increase in complaints. Hip and knee implants are known to have complications, including infection and joint dislocation. Hip replacement lawyers predict that hundreds or even thousands of patients are now facing hip and knee revision surgery, or multiple revision surgeries.
One reason that so many hip and knee replacements have failed is due to manufacturers introducing their products to the market with little or no clinical evidence, according to a report in The Lancet, March 2012. When problems with hip and knee replacement devices were detected in the past, surgeons typically stopped using the faulty device and the manufacturer recalled the product. But some implants have not had a recall even though complaints have been filed--such as with Zimmer’s NexGen knee and its Natural knee and hip.
A recent study reported by The International Herald Tribune, (December 2011) found that no new hip or knee implants introduced during the last five years were more durable than older devices, and 30 percent were worse.
Patients with hip and/or knee replacement failure have reported the following problem(s):
A recent FDA website (October 2011) notifies the public of the concerns regarding use of metal-on-metal hip components used in total hip arthroplasty (THA). It describes hip implants, how metal-on-metal implants differ from other hip implants, and it gives information and recommendations about the benefits and risks of these medical devices. It also notifies hip replacement patients about symptoms that might indicate a hip replacement problem, including hip/groin pain, local swelling, numbness or changes in your ability to walk.
Hip Replacement Failure
Metal-on-Metal total hip replacement systems consist of a metal ball (femoral head), a metal femoral stem in the thighbone, and a metal cup in the hip bone (acetabular component). MoM hip implants are usually recommended for younger and more active patients, mainly because they are supposed to be more durable and last longer than other materials, i.e., plastic or ceramic. Metal-on-metal hip implants are made of a cobalt-chromium alloy.
Metal-on-Metal Total Hip Replacement Implant
The two types of MoM hip systems are Traditional total hip replacement implant and Total resurfacing hip implant. According to the FDA website, metal-on-metal hip implants are known to have adverse events, including infection and joint dislocation.
A report released by the National Joint Registry for England and Wales (09/11) warns that the failure rate of metal-on-metal hip devices is increasing, with the highest failure rate seen in the DePuy ASR device. According to the registry, hip replacement devices made entirely from metal had a significantly higher failure rate than those made from other materials. The failure rate was also significantly higher in women than in men. The report found that of patients who received an ASR device six years ago, approximately 30 percent had the device replaced. Failure of a hip device is not considered life-threatening, but can be debilitating.
Meanwhile, a study published in the British Medical Journal (11/11) suggested that metal-on-metal hip replacement devices are no more effective than traditional hip replacement devices and may have higher revision rates than their traditional counterparts. According to researchers, patients who receive a metal-on-metal hip replacement device have approximately double the risk of undergoing hip revision surgery.
The DePuy ASR XL modular acetabular cup and the ASR hip resurfacing system were recalled in August 2010 after hundreds of patients complained about the metal-on-metal hip implants. From August 2005 to August 2010, about 40,000 in patients in the US received the DePuy ASR and the failure rate could be as high as 13 per cent. (The generally accepted standard is no more than 5 percent of patients requiring revision surgery within five years of implantation.)
Anyone who received a hip replacement in the US after July 2003 may have received a DePuy ASR device that is defective.
DePuy ASR Infection
The design of the DePuy ASR causes the metal ball and the metal cup to slide against each other during movement, which can cause some tiny metal particles to wear off of the device and enter into the space around the implant. Metal ions from the implant may enter into the bloodstream, which may cause severe medical problems. Some patients with metal-on-metal hip implants developed a reaction to these ions, which could affect the nervous system, heart and thyroid gland. Metal debris in the bloodstream can lead to cobalt poisoning or toxicity.
DePuy ASR Slippage and/or Joint Dislocation
Metal particles around some implants can also cause damage to bone and/or tissue surrounding the implant and joint, which is called "adverse local tissue reaction (ALTR)" or an "adverse reaction to metal debris (ARMD). This reaction may cause pain and/or the implant to loosen.
letter to surgeon.
Since it was introduced to the US market in 2006, the Durom Cup has been used for total hip replacement in more than 12,000 patients, but many individuals have reported severe pain and the need for additional hip surgeries after having the Zimmer Durom Cup hip replacement implanted. According to the manufacturer, doctors reported post-hip surgery problems "requiring revision" 5.7 percent of the time. Some patients have also experienced problems with the Zimmer NexGen CR-Flex knee replacement component.
According to the FDA MAUDE Adverse Event Report, DePuy is currently investigating loss of osseointegration with the DePuy Pinnacle device.
Similar to the ASR XL Acetabular and ASR Hip Resurfacing Systems, the DePuy Pinnacle Acetabular Cup System was fast-tracked through the FDA's medical device approval process because it was similar to already-approved devices. However, unlike the other hip systems, the DePuy Pinnacle Acetabular Cup System has not yetbeen recalled. Regardless, DePuy Pinnacle lawsuits have been filed (see below).
People who had the implants reported difficulties with the products since 2005, including severe and intense pain, trouble walking, joints that squeak, broken joint implants, and poor fit of implants leading to bone breaks.
Corin Group, based in England, has had a partially porous femoral component available in Europe for several years. The Cormet Hip Resurfacing System was approved by the FDA in 2007. Although the agency supported Corin’s hip resurfacing device, it required a follow-up study after approval to evaluate long-term performance.
Corin Hip Resurfacing
Hip resurfacing was introduced in the late 1990s as an alternative to the more conventional total hip replacement. It is mainly designed for middle-aged patients who are physically active and expected to outlive the l 15-20 year lifespan of a full hip replacement. However, a British study by The Royal College of Surgeons (September 2008) found about 4 percent of the 2,360 women who underwent resurfacing in England had to have a second operation to repair the same hip within three years. Those women who received traditional hip replacements had a re-operation rate of less than 1.6 percent.
US Research (Clinical Orthopaedics and Related Research, January 2009) found that most complications with hip resurfacing occurred in women of all ages and men over the age of 55. Resurfacing in the US is expected to increase, despite the risks.
The Biomet Magnum Hip Implant is a metal-on-metal implant that is allegedly a defective design. A lawsuit has been filed against Biomet Orthopedics claiming its M2a-Magnum System failed shortly after being implanted (the plaintiff received the Biomet hip replacement in 2009). According to the lawsuit, the Biomet hip replacement device has caused a condition known as metallosis (metal poisoning) due to the metal hip replacement parts rub against each other, which can lead to microscopic particles of cobalt and chromium shedding into the body.
Biomet Hip Replacement
Biomet has recalled three of its following products:
Sometimes knee replacement surgery fails and knee implant revision surgery is necessary. There are a number of possible causes of knee replacement failure, however, complaints have been filed regarding alleged defective knee implants.
Knee Replacement Failure
Zimmer NexGen knee recall, but product liability attorneys and personal injury attorneys are evaluating Zimmer knee claims for patients who have experienced failure with the Zimmer NexGen CR-Flex Porous Femoral component.
In 2012 Zimmer’s Natural-Knee II Durasul Patella product was issued a Class II recall for its knee replacement component due to reported device failures.
In August 2003, the London-based medical device manufacturer Smith & Nephew recalled of two of their knee replacement products--the Oxinium Pro-Fix II and the Oxinium Genesis II. Some of these "cementless" knee replacements failed to bond properly, which greatly increased the possibility of infection, as well as joint, muscular and neurological damage in addition to further painful rehabilitation and revision surgery.
Other Hip and Knee Replacement Issues
Some Hip and Knee Implant failure problems can be traced back to several companies' sterilization practices. Howmedica, as well as several other companies, used a technique known as gamma irradiation in air to sterilize the devices (hip and knee prostheses) made of high molecular weight polyethylene, which is like a pliable plastic. The sterilization process caused the polyethylene part of the devices, once implanted in the body, to break up into small pieces that lodge into the patient's hip or knee joint. In the body's fight to rid itself of those pieces, the immune system also turns on the patient's healthy bone, causing it to decay, a condition known as osteolysis. These patients inevitably need a second surgery to replace the device long before expected.
Oxidation, which is a time-dependent byproduct of gamma sterilization in air, has an adverse effect on the material properties and wear resistance of polyethylene. Oxidation occurs when oxygen combines with free radicals in the. The oxidation can occur during irradiation, or it can occur over time as oxygen diffuses into the polyethylene and combines with residual free radicals.
Recognizing the adverse effects of oxidation, some manufacturers have abandoned gamma sterilization and began using ethylene oxide (EtO) or gas plasma to sterilize the components, thereby avoiding immediate and long-term oxidation. However, particularly in the absence of oxygen , the free radicals generated by irradiation can combine to each other, forming "crosslinks" between two carbon atoms on adjacent polyethylene molecules.
When packaging/sterilizing in a low-oxygen environment (e.g., partial vacuum, inert gas, or with an oxygen scavenger), the degree of oxidation that will occur is reduced. In order to gain the benefit of the crosslinking, some manufacturers continue to sterilize their polyethylene components with gamma radiation.
Defective Hip Implant Symptoms
The following symptoms that could occur after your hip implant surgery may indicate that your artificial knee or hip is not working as it should, and may require revision surgery:
Defective implants require removal and revision (also known as replacement) surgery at significant expense. Your orthopedic surgeon may recommend revision surgery for a number of reasons, including infection, dislocation, and device fracture. Revision surgery may be advised if you develop evidence of local or systemic reactions to the metal from your hip implant.
Researchers believe that data on knee and hip replacement surgery is mostly limited to revision surgery, which means the number of complaints from hip and knee replacement patients could be the tip of the iceberg. Many patients suffer pain and disability without undergoing revision surgery.
Complications from revision surgery include:
As of November 2011, more than 5,000 lawsuits and complaints had been filed against the makers of all-metal replacement hips alone.
Hip and Knee Replacement Lawsuits
The following manufacturers have lawsuits filed against them for faulty hip and knee implants:
According to Medical Industry Week, on February 18, 2011 a personal injury lawsuit was filed against Johnson & Johnson's DePuy Orthopaedics, alleging its DePuy ASR XL acetabular system is defective. The lawsuit has been filed in a Federal Court in San Francisco, CA.
One DePuy Pinnacle lawsuit, which was filed in November 2010 in the U.S. District Court for the Central District of California, claims that the plaintiff has been suffering from an abnormal gait, nerve pain and other problems since receiving the Pinnacle device in 2004. Another suit, filed in December 2010, in the U.S. District Court for the Western District of Washington, alleges the plaintiff has undergone six surgeries as a result of metal poisoning he developed after receiving a Pinnacle hip implant in 2007.

The replacement was put in in May 2014from day one i told the dr i was in alot of pain and thr knee would not been. After alot of doing this and that nothing helped.After a year of pain pain pain my dr.said it was my fault it wouldn't bend.I ask him how is it my fault when I've.

Had a conformis itotal g2 implant November 2014. severe shin pain anyone have answers to this. I have been tested and am highly reactive to nickel and the implant will be removed in December. Yet No answer as to why so much pain in knee especially shin.
I had a TKR in April 2013 (Stryker Osteonics Triathlon). I had constant pain during physical therapy. The joint was always warm or hot. My doctor insisted that this was normal, even after several months post-op. He told me that I had a low pain tolerance and "this would be as good as I may get out of the surgery". Nine months after surgery I began to get fevers and red steaks down my leg. I saw my primary care physician who said the knee was infected and referred me back to the surgeon. Immediately, I was taken seriously. I did have a 2 stage revision (done by another surgeon). I had filed a law suit, suing the surgeon but it went no where. I was told it was because the outcome would have been the same - a 2 stage revision. The second knee is working out but I am still in pain and there is significant swelling but I can at least function. Is there any information re: the Stryker Osteonics Triathlon?
Had total knee replacement at VA hospital ..one year later knee still swollen and was told by doctor that it was fine. Had x-ray and he said that was fine too. Then about one week later called and said I needed to come in due to something abnormal on the x-ray.
Of course when I got there I never saw my doctor again but was seen by another who said he didnt know what had happened but I would need another surgery to replace the joint.
My wife has had to give up her plans for a federal job in order to care for me as I am having difficulties and will need a new surgery. We are seeking damages for malpractice as well as pain, suffering and loss of wages.
I had a total knee done 2006 at VA hospital. I had knee pain from day one they say everything looks good.they just give me more pain meds.it a depu implant. Now I have to get rep la e at a not her hospital.

I lost all range of motion. nothing can touch my knees with out it feeling like a boulder hit me. I walk up and down the stairs 1 step at a time. I tore the ten dents in both shoulders because of the way I have to get up from any sitting position. I live with constant pain.

I had a Stryker Triathlon installed in Jan. 2010. In the past year I have suffered stiffness pain and lack of mobility. I am facing revision surgery in April. Do you see any chance of legal recourse?
In 2012, I had a total knee replacement. And as of April 20, I have to have surgery to redo the knee because the part is loose.
In July 2012, I had a Zimmer hip replacement. Since then, I have increasing pain and walk with a severe limp. July 2014, it was discovered during an X- ray, that the titanium rod inside the femur had broken in two inside the femur. December 2014, I had a seven-hour surgery to have the piece removed and replaced. I had complications right after the surgery. The doctors at Hershey Medical Center in Hershey, PA, had never seen anything like it concerning a clean break in the rod! Unfortunately, I can't find a law firm willing to take my case on the sole basis that they haven't found enough similar cases. My medical bills are coming in and I need help. The surgeons have kept the metal piece in the event we need it for a lawsuit.
I had a knee replacement in December of 2012 and had severe swelling in the knee after the surgery for 15 months. I knew something was wrong, as my surgeon had to removed up to 200 ccs of fluid from my knee every few weeks. The pain was worse after surgery than before. It was so bad, that I considered amputation.
I had a total hip replacement on June 26, 2001 started having problems in 2011. I had to have a revision on February 14, 2012 and a 3rd surgery on January 27, 2014 due to complications from the 1st replacement. It wasn't a metal to metal but metal on plastic but I have had the same issues as the recll implants. Do anybody know of a lawyer that will take my case? This is a problem that I will have for the rest of my life.
Partial knee replacement done on 10/27/2010. On 10/15/11, less than one year, the partial came loose and came out of the thigh bone. Had to wait until 11/18/2011 to have the partial taken out and a complete knee put it. I lost my job because of the time I missed and I ran out of leave of absence. I am now on disability and suffer daily with my knee.
My story goes all the way back to 1980 when I was at work and my left knee popped out of place. The pain was excruciating. I couldn't straighten my leg out at all. A customer came and I asked him to call my Parents house and my Dad came and picked me up. We picked up my Mom on the way to the Hospital because she had to fix her hair--lol. She didn't realize the pain that I was in. We finally got to the Hospital and when the Doctor came into the Emergency room, he said that he was going to have to straighten my leg out. Have Mercy, when he did, I thought that I put dents into the rails on that bed. He put an immobilizer around my knee and told me to use crutches for 6 weeks and come back to his office. I did what he asked me to do and when I went back to his office, he told me that the main muscle that crosses over your Patella stretched completely out and I would need surgery. I wasn't but 25 years old. I was scared to death and when I woke up, he had put my whole leg in a cast. Needless to say, the pain was so bad I thought he had cut off part of my leg. I finally got to go home and then a week later I had to go back to his office. I talked him into taking the cast off and putting me back into the immobilizer. He had me sign a consent form releasing him of any liability in case I fell or anything like that. This was in the middle of the summer and that cast was HOT!!! So everyday I would go outside, take my little girl with me and watch her play and open up my immobilizer so my BIG cut could get some sun. When I went back to him 2 weeks later, he couldn't believe the difference in my cut and asked me what I had been doing so I told him. After I got over that surgery, my knee did pretty good for a while. I never could bend it all the way or run anymore, but I could walk without any pain--until1994. I ended up having Endoscopic surgery on it. That Dr. went in and cleaned out all the arthritis that he saw. It did pretty good again until 2008 when I had Arthroscopy surgery on it. He cleaned out the arthritis again and tried fixing a meniscus tear that I had. After that one, it didn't do too good so in January of 2010 I had a Total Knee Replacement. I did real good after that one. Until about a year ago when it started popping. And about a month ago it started popping out of place. I can't believe I'm going through all of this again. I'll be 59 in May. It was supposed to last 15 to 20 years and it hasn't lasted 4 1/2 years. It hurts pretty much all the time now, it swells and to top it all off, the Dr. that did the surgery then, isn't under my Insurance Network now. What's a girl to do? I'm going to call the Dr. that did it, find out my last visit there, ask them if they know the name of the Implant, which they should, but if they don't--then I'm going to call the Hospital where I had the surgery and ask for and Itemized Statement and tell them to be sure that the name of the Implant is on there. PLEASE be careful if you're thinking about having any kind of Replacement. Ask your Dr. for the name of it and do research on it. It's your body and it's the only one you'll ever have. You won't be sorry doing the research--besides--you're paying the Dr. not the other way around. May God Be With You...
In February of 2011, I was fitted with a recalled DePuy knee prosthesis. I have had nothing but problems from that time to the present! Painful, swelling, clicking with something moving within the knee, and failure to support me are just some of my complaints.
I Had A Knee Replacement In December 2012, The Part Was Osteonics Triathion Stryker. Went Back To The Doctor Several Times And Told Him I Was Still In Severe Pain. He Did X-Rays And Biopsys On It And He Said He Couldn't Find Anything Wrong That Was Causing My Pain. It Will Be A Year This December, And I Still Have Severe Pain, Can't Hardly Walk Without Hurting. I Have Almost Fell A Few Times And I Am So Afraid I Will, Could There Be A Defect In The Stryker Implant?
