Do PEEK screws dissolve?

In addition to its biocompatibility, PEEK also resists attack in an organic or aqueous setting, so it will not corrode and it will not absorb minimal moisture. PEEK screws can be implanted anywhere in the body and remain intact for years.

For the most part, patients’ range-of-motion 10 years after surgery was the same as it had been two years after the operation. About 85 per cent of the 502 patients had a stable knee they could hop on.
