@nprofile1q... I'm sure every situation is wildly different so this is not so much advice as just reporting what I did. After injuring my knee (some sort of hyper-extension and bone bruise playing soccer) I spent several months alternating between an elliptical machine, exercise bike, and walking for exercise. We joined a local gym (basically the local high school gym since we are semi-rural.) I always figured if I bought any big exercise equipment it would probably just collect clothes hangars, and joining a gym let me use a variety of equipment. Eventually I started running once every 2 weeks on a treadmill which was easier on my knee than running outside ... and then after a couple months of that started doing once every week. I still wear a knee sleeve, but I'm back to being able to run a couple times a week ... but now I'm to the general age where I run every other day at most to give my body a chance to heal. And I've even started playing some pickup soccer (sorry, football) again with a local group. Anyhow, wishing you the best with your recovery and hope you are back to running sooner than you expect.
