Reasons for Recall
Device Explained: A total knee replacement usually consists of four component parts (shown above): the femoral component, tibial baseplate, tibial insert (plastic), and patella. The only component part that Zimmer recalled is the metal tibial plate (shown below) which can become loose requiring revision surgery. Zimmer claimed the Trabecular Metal Technology eliminated complexity, procedure time, and third-body wear by removing cement from the surgical procedure.
There have been 40 complaints worldwide of the device loosening, as of March 16, 2015. At least 16 of these complaints have required revision surgeries.
Reported Side Effects & Complications
- Loosening of the implant
- The appearance of radiolucent lines
- Severe Pain
- Difficulty Walking or Bending the knee
- Knee Instability
- Knee Tightness
- Numbness or stiffness in the leg
- Revision surgery or recommendation for revision surgery
According to Zimmer, the recall affects 11,658 of these knee components worldwide. Zimmer distributed the recalled Persona Trabecular Metal Tibial plates in at least 25 states and at 13 major Veterans Administration centers.
Types of Loosening
There are two types of loosening: aseptic and septic. Septic loosening is loosening to due infection which is proven by positive cultures or a sinus tract communicating with the joint at revision. Aseptic loosening is loosening caused by micromotion, bone stock deficiencies, inadequate porous coating design or contaminants.

Frequently Asked Questions
The operative report and knee implant labels, often called Chart-Stick® labels, from the hospital will identify the specific devices that were implanted
Always consult your doctor or surgeon regarding health-related issues, but if you or someone you care about received a recalled knee replacement, we would like to speak with you right away. DO NOT SIGN A RELEASE FROM THE SURGEON OR ZIMMER. This release will allow Zimmer complete access to your medical records and also allow them to obtain the failed implant in the event it is removed.
If you have pain and/or swelling in or around your knee replacement, you should schedule an office visit with your orthopedic surgeon to discuss your symptoms and to have radiographs (such as X-ray/Bone Scan/MRI) performed to see if there are signs of radiolucent lines or loosening. Additionally, consider keeping a journal of your symptoms. We have found this to be extremely helpful in representing clients and it assists us in personalizing your claims when we present them for settlement or trial
Even if you do not have symptoms at this time, you should at least visit your orthopedic surgeon for an evaluation and have radiographs performed. You should continue the postoperative plan outlined by your surgeon. Pay close attention to any pain or problems that you believe are being caused by your knee implant.
If you are experiencing any of the symptoms described above, you need to see an orthopedic surgeon to be evaluated. The only way to confirm loosening is by radiographs such as X-ray/Bone Scan/MRI. Pain and swelling are symptoms of loosening.
Potentially. If there is any evidence of implant loosening or radiolucent lines around the tibial portion of the knee replacement, your surgeon might recommend a revision surgery to remove and replace the uncemented tibial plate. This is a difficult decision that you must make based on your surgeon’s recommendation. The only way to resolve a loose tibial plate is to remove and replace this component part. Q: What if I already had knee revision surgery? A: It is important to speak with a lawyer immediately as your statute of limitations has begun to run. Additionally, it is important that the device that was removed and replaced is located and preserved.
No. You should contact a lawyer before communicating with Zimmer and avoid signing a release. We do not recommend providing Zimmer with a release or providing them with any of your medical records.
We only sue the implant manufacturer for designing, manufacturing, and marketing a defective product. We do not sue the implanting surgeon or hospital.
