Why does your body not attack metal plates and screws after surgeries?
In: Biology
Some of the plastic materials used in early joint replacements had a problem of creating small particles as they wore down. These particles inside the joint caused an immune response where the implants were attacked by the body and loosened up. Luckily, doctors learned and changed these. I have had both knees and both hips replaced all with different materials because of insurance coverage. My right hip is the oldest at 20 years old. It is part ceramic.
