Defective Knee Implants May Result in Chronic Pain and Serious Injuries. Contact a knee implant recall lawyer to discuss legal options following device defect injury


If an artificial knee replacement system fails for any reason, whether the device components prove defective or implant components wear down over time, revision surgery may be necessary. Most revision procedures will include surgeons removing a faulty device and most likely replacing it with a new implant. Each year in the U.S., thousands of knee revision surgeries are performed after patients experience complications.

Experts from the American Academy of Orthopedic Surgeons warn that revision surgeries can cause significant damage, and even permanent injuries, as health risks are known to increase with each successive medical operation. Too often, patients are unaware of these risks when they undergo their initial replacement surgery.

Medical device companies, like Zimmer, Arthrex and Exactech, who market and distribute artificial joint products to consumers should clarify the risks, and take responsibility when their devices fail and cause serious injuries.

Knee Implant Failure & Revision Surgeries


Knee revision surgery can be required after a patient develops an infection, experiences unusual pain, or finds a decreased range of motion after an implant malfunctions. Recently, some recipients of defective knee implants have reported a loosening of device components, and an overall instability months or years after an initial implant operation.

The cause of knee implant loosening is not always clear, though high-impact activities, excessive body weight, and wear of implant components are all contributing factors. For anybody with an implant from Arthex, Exactech or another device maker, there is a long-term risk that revision surgery will be needed due to loosening or wear.

Another common reason for revision surgery is the occurrence of bone loss, which can occur from either a defective device design or from normal friction and excessive wear on the bones from implant components. Implant recipients cannot expect artificial knees like the Arthrex or Exactech system to function perfectly forever, though there is a reasonable expectation from medical device companies that their products perform as they are marketed.

•    Loosening of an Implant—there have been multiple complaints from Zimmer, Arthrex and Exactech knee implant recipients of a general throbbing pain and instability that is due to a loosening of the device. This may be due to either faulty device design, and the bone may not fuse properly with an implant.
•    Bone Fracture—when a device is loosening, and creates unnatural friction and structural damage, it may result in bone fractures.
•    Infection—if a patient notices unusual swelling and inflammation in their knee after an implant surgery, or if blood tests indicate serious infection, a revision surgery may be needed to remove potentially dangerous components. Some devices have been known to cause metallosis, a type of serious metal poisoning from implanted components.

•    Knee Instability—a general instability or decreased range of motion may occur if knee and leg ligaments are damaged or improperly balanced during an initial replacement surgery.


Knee Implant Revision Surgery


Recovering from knee implant surgery can be long and painful. Rehabilitation is likely to last several months. It may come as a shock and great inconvenience when a device fails and another surgery is necessary. A second surgery required to adjust or replace an implant raises the risk of complications. This can result in huge medical bills, serious emotional distress, and a great deal of time away from work. Lost wages and other damages can be recovered in timely lawsuits.

After receiving defective Zimmer, Arthrex or Exactech knee implants some patients may feel persistent pain or notice that their new joint is not as flexible as the joint was prior to the operation. This may be a symptom of a greater issue, and some complications that may follow include:

•    Blood clots
•    Knee joint immobility
•    Nerve damage
•    Muscle damage
•    Bone loss
•    Infection


Defective Knee Replacements


Recipients of defective knee replacements who experience any symptom of device failure such as serious throbbing pain, difficulty standing or moving, or feeling of instability should contact their implanting surgeon and a knee implant recall lawyer for immediate consultation.

Medical devices have been known to dissemble, cause bone fractures, damage nerves, cause infection, and other injuries. Zimmer, Braun, Arthrex and Exactech and other device companies issue recalls for defective products, though sometimes thousands of patients are endangered before the faulty device is removed from the market.

This causes more revision surgeries, more potential injuries, and more lawsuits directed at the companies responsible for failing to properly test or warn American consumers.
