We have multiple anatomy books in the reference section (check under REF QM), but this one is particularly good for your topic.
Use these sources to find quick background information on your particular joint - good for when you can't get to the library.
This is a searchable, 3d model of the human body - very useful for seeing how your joint interacts with it's surroundings. Free, but requires registration. If you don't want to make your own account, there are other methods you can use.
