Damaged meniscus acl and possibly more can you dislocate your knee from simply standing up out of a chair?

I had to wait a year between injuring my knee and getting and MRI and for the most part I had no trouble with day to day activities

I disrupted my knee several times during that period standing up from a chair, and it would also happen sometimes if I did a deep squat or knee bend.

My MRI showed a torn acl and a partially torn meniscus.
