Knee Recalls and Kicking Buckets

August 3rd, 2018

As joints go, the knee is pretty simple. It allows the leg to bend in one direction. Compared to the complexity of directions allowed by the shoulders, hips, and wrists, it does just one thing. So it needs to do it well. And just as your knee has to do it well, so do the replacements when they become necessary. Alas, it doesn’t always happen that way.

Zimmer is the world’s largest manufacturer of artificial knees. And they are having a recall on their Persona Knee implants. Technically the full name is the Zimmer Persona Trabecular Metal Tibial Plate knee implant, but we’re just going to call it the Persona.

The Persona is having issues. It can cause Radiolucent lines – these are large gaps in between the knee replacement component and the bone, which can be problematic.

These problems may include implant failure, pain, swelling, tissue damage and osteolysis (medical for bone damage). This may need to have the knee replacement redone completely – as if having it done the first time wasn’t fun enough.

In theory, a knee implant should last twenty years. Yet many of these have failed within three years. If the complications are serious enough it could be deadly.

If you have had a knee replacement and are having issues talk to your doctor.  And talk to us.
