Hi, I had meniscus repair in 2015 and was told I have arthritis in knee and had bone spurs that were removed and would probable need a knee replacement in a few years. This year started walking 2 miles a day, some squats and stairs with no problem. A few weeks ago my dog got out of the yard and I chased her, I felt like I stepped wrong and felt pain in my knee for about a week. I rested my knee, iced it and felt better but now feels like it wants to give out but I have no pain. I went to an Ortho who examined it and looked at X-rays taken in 2016, gave me a band to wear beneath my knee and told me to rest and ice it and offered me a cortisone shot which I denied because I have no pain but still feels like it wants to give out with a little pain so I have requested a second opinion and new set of images. I m frustrated, any other suggestions?
