I thought tissue degeneration was part of the issue here? Having regenerated tissue doesn't necessarily help if you stop taking the drug and the tissue just goes away again.

(It sounds weird to me that tissue can just disappear from that area so I think this might be wrong?)

If tissue gets regenerated, it shouldn't "just go away again" once you stop the drug unless perhaps there is an unidentified pathological process involved.

yeah, I too find it weird to imagine that tissue can just disappear from the inside of a joint. where would it even go? does it melt into the bloodstream or something? lmao
