I mean, a trip to Europe involves almost always a lot of walking.

Part of a trip overseas.

You know, the most common is just wear and tear, what we call degenerative arthritis.

And the most common cause of that is probably an old injury of some sort, even an injury that the patient doesn't remember or recognize.

But over millions of cycles, that part of the knee just starts to wear out.

And it's usually the inside half of the knee.

uh that starts to wear out and then as it starts to wear out that you know you'll see people walking around like cowboys you know they start to get a bull legged well that's kind of a nutcracker you know it just increases the pressure on the inside of the knee it increases the wear there's there's always been some argument as to whether you can wear out a normal joint and uh you know you may not be able to wear out an absolutely normal joint so

People are either born with a malalignment of the joint, have an injury, or they have these other what we call metabolic conditions, the various forms of systemic arthritis, rheumatoid arthritis, psoriasis.

These that affect not only your joints, but other body organs as well, not isolated to just the knee.

But yeah, wear and tear, it's just like you're

Transmission in your automobile, you know.

Yeah, well, they're all basically metal and plastic.

The metals that are used are alloys.
