I had a knee injury a while back that had my on crutches for about a month. Afterwards running or skiing (winter favorite) was a no go. I went to physio and they gave me some exercises. So I would suggest that. However if you are looking to add something to your routine in general to help your knee I would suggest looking into some balancing board exercises.
Here is what I do:
First balance as you normally would on the board for about 2 minutes.
Second controlled balance leaning forward and backwards but not letting the board touch the ground.
Third like the second but side to side.
Repeat that 3 times. If you want go longer.
Main thing is to keep your balance if you need to stabilize everyone and a while then exercise near something you can hold on to our touch to catch your balance again.
