What are the different types of artificial knee joints?

There are different types of artificial knee joints (prostheses). The main difference is whether the prosthesis replaces the entire joint or only a part of it. Both types of prosthesis have pros and cons. The most suitable type will depend on various factors.
The choice of knee prosthesis will mainly depend on the condition of your ligaments, muscles, and bones. Your age and weight play a role too – as well as how physically active you are. If you’re allergic to certain metals, coated implants are used. You can discuss suitable options with your doctor. It is also possible to get a second medical opinion before you decide.
