Have you completed all your physical therapy and have you attempted to exercise the knee? Typically, scoping a knee is a very minor procedure however if you don’t work through the pain a bit and get the blood flowing in there the scar tissue will build up making it painful to move. I’m not a doc however had 2 medial meniscus arthroscopies and each time have found that the sooner you can get in there and work the area (Stretches, light weights, etc…) the better it responds.
I’m sure you have been told this by your Doc, but it is the only thing I can think of. Also age may play a role. When you are young your body recovers from any type of minimally invasive surgery much quicker than when you are older. If it’s your first arthroscopy and only cartlidge was removed I think you will be fine. I’ve had 2 and have run several marathons since. Maybe you just need some more time.
In any regard, Good Luck
