As a total amateur with no possible credentials at all, what is your wild ass guess?

Osteoarthritis would be MY wag. And that's ONLY because my Spousal Unit has experienced similar episodes (not to complete buckling) but her diagnosis was the same. She also has small meniscus tears (she's 71 btw) which also contributes.

I suspect you will get an MRI at some point and then you'll have your definitive answer imo 😏 Good luck.

You are correct though, I have NO background in orthopedics- I was cardio-vascular centered the last 20 years of my career although my Spousal Unit was the surgery and infection control "expert" in the family- she had all kinds of orthopedic experience.
