Another physio visit. Different therapist today. We went through my exercise program and she eliminated several of the exercises, given that I am already able to do many of the harder ones.
Given that I seem to be functioning so well without an ACL (alternating lunges, single leg squats, balancing on bosu, no pain), we are wondering if I already had a partial tear for years and was functioning with it but didn't know (maybe this also explains how I feel like I snapped my ACL kind of easily?).
All that said, I'm still not allowed to do any activities that would involve pivoting and risk having the knee give out again. A knee brace won't let me do extra activities but might be good to have for extra protection for trail walking, easy flat xc skiing, nice to have during recovery after surgery.
As for whether any of this changes the decision to have surgery, her reply was that surgery should be pursued unless you have some reason to not have surgery (e.g. don't have coverage and can't take the time off work, etc.).

Physio Exercises: (adjusted program from Lynne)
(No holds except glute bridges, use weight to max/tired at end of workout, aiming for good workout but no aggravation, 3x15 is a good amount of reps and sets for all exercises)
Single leg calf raises: 3x15, progress to not holding onto anything
Single leg glute bridge with holds: 20 reps x 10 sec holds?
Hamstrings: full range from leg extended to tucked under butt, 3x15, whatever weight I can tolerate. Used easy pulley.
Muscle stim for all quad exercises:
Double squats on flat with weight: 3x15, don’t go past 90 degrees, don’t even need to go that far. Used 2x25lb dumbbells. Could try heavier.
Single leg squats on flat, no weight: 3x15, progress to not holding onto anything (*these are my most important exercise*)
Double leg squats on bosu: no weights, don’t go past 90 degrees, don’t even need to go that far. These felt easy, no worries about knee stability.
Alternating lunges, 3x10, no weights, on flat, don’t let knee go forward of toe just drop down. Wore hokas to not aggravate toe. These felt easy, no stability worries.
Single leg balance on flat. These feel easy.
When to try single leg balance on bosu? (Holding onto something?)
