That's some routine!
I've done nothing at all in the way of physio or deliberate exercise, other than trying to be as normally mobile as possible. I'm walking OK, sometimes with a stick. Up and down stairs is fine, slowly and carefully. Every day is slightly better, but some days I need to take it easier and keep my leg up. Not pain as such, more just feeling weak and feeble if I've overdone it the day before.
Re-tear fears - I've had the occasional pain in the knee cap but I think this is par for the course. Judging from this forum re-tearing doesn't seem to be a risk from normal activity - unless you fall again etc.
Starting physio this week. Not planned this way - 2 weeks late - the reference got lost in the post!
So I'm making reasonable progress I think, but looking forwards to seeing if this can be speeded up.
I'm 67 and was fit and active cyclist/walker before all this.100 mile bike or 20 mile walk no prob, I get the impression that mid 60s seems to be the age for it. Is the previous level of exercise an indirect cause? A lot of posters here some to be active types!
In my case the direct cause was just a little slip in the snow down three steps. Nothing much at all.
