You can segment the structures you want to measure (see segmentation tutorials [here](https://www.slicer.org/wiki/Documentation/Nightly/Training#Slicer4_Image_Segmentation), and you can find additional youtube videos if you do a search), and then you can get their volumes in the Segment Statistics module.

You can get cartilage _thickness_ as described here:

> “Thickness” is not a very well defined term for models (surface meshes), but for shell-like meshes it is probably not too difficult to estimate it robustly and accurately. Potential approaches: A. Extract medial surface and estimate thickness as 2x of distance from medial surface. There are various ways of computing these in Slicer. One possible workflow: Compute medial surface using Simple Filters module - BinaryThinningImageFilter. Compute distance map using Simple Filters module - Daniels…

That’s perfect. Export the segmentation to model (right-click on the segmentation in Data module) and then follow the steps described in the linked post.
