Orthopedic supply companieshave begun to market directly to consumers. Their advertisements might make you believe theirknee replacement implant is “the best” and worthy of considering above all others.
The truth is, the best knee replacement device is generally the one that is most appropriate for your condition. How long the device has been on the market and whether your surgeon has experience using it should factor into ranking your options, as well.

This article discusses knee replacement implants and how healthcare providers determine which one they will recommend.
Differing Opinions on What’s “Best”
There are many orthopedic manufacturing companies that produce different implants used in knee replacement surgery. Most of these companies make several different knee prosthetics.
One of the most important aspects of knee replacement surgery is determining the proper implant to be used in the operation.
Orthopedic surgeons may not always agree on which one of these implants is the “best.” This may be because they also disagree on what criteria are most important. For example:

Long-Term Research Is Lacking
There are thousands of studies published in the scientific literature evaluating various knee replacement implants. Unfortunately, the studies are generally performed to prove that an implant that is coming to the market will perform satisfactorily.
Studies have not been performed to compare the long-term results of different implants over decades of time.

Summary
The best knee implant device is the one that is has a good track record and is most appropriate for your situation. It is also a good idea to choose a device that your surgeon has experience working with.
A good device is one that restores normal function to your knee and lasts for your lifetime. This makes it difficult to say which manufacturer makes the “best” device, since many have not been on the market long enough.
If you have a specific device in mind, ask your healthcare provider to compare it to the device that they are most familiar with.
