does it sound to you like your leg is rehabbed properly?
if 'normal' to yuo is walking, stairs, jogging then sounds like you are good to go.
if you are happy with a smaller weaker leg with feeling of instability and weakness...
how do your UNWEIGHTED squats feel? i'm kind of a firm believer in 'you don't have any business doing it with loading if you can't do it without loading'.
(actually sometimes loading helps the exercise be a little easier etc etc but i still stand by that general point most of the time).
knee instability typically arises from:
tightness / restriction in the hips and / or ankles. how is your hip / ankle mobility doing??
one legged movements would probably be good for your rehab... to bring up your weak leg. make sure you knee is tracking properly over your ankles and don't let weak / unstable hips / ankles have your knee roll in...
