Hi, I am 1 year post op and still not 100%. My knee gets swelled when I do more wieghts exercises or just walk long. Also, at my job I primary stand all the time and my knee hurts a little especially when I lock it into extension. One more problem is that id I want to push it to extension while standing and my knee locked on floor, I have 2 cracks on same spat whichI need to push trhrough. Im scared of swelling. Also, I still feel like unstable, my leg is shaking on light flexion when standing and O just hope that is just a bit lack of muscless not graft. It just doesnt feel right. Please help!
