Anyone late 30’s early 40’s with a TKR?

Hey everyone.

I’m a 36F with a totally trashed knee. Multiple large regions of grade 4 with complete collapse of the lateral compartment. I push through a lot, rehab regularly, and often do okayish because I’m stubborn and passionate about some hobbies, but currently am not doing well.

Just curious if there is anyone out there my age that has undergone a TKR and what that’s been like as a young recipient. I’m having the worse flare up I’ve ever had and super discouraged. Thanks
