I read all your posts and couldn't understand why your PT said not to try to walk until 6-weeks. I had to walk every hour on the hour up and down the hall until I was discharged and then was encouraged to continue to walk inside my home throughout the day. I did use a walker which helped keep the weight off my knee and helped with balance. This actually helped with my pain. I did online PT and each month my walking time increased. Are you resting in bed or a recliner? Are you elevating higher than your heart? At 10 months my knee swelled and was stiff more times than not. Do you live alone? It sounds like you could benefit from a nonaggressive form of PT to get you back on tract. Don't give up.
