Trick knee-will it resolve

Question
Nick
Two years ago I sprained my right knee running. It took almost two years to heal. My doctor said there was no damage, just a slight meniscus tear. I am sure my age, 55, and excess weight were also mitigating factors.
Since then I have lost a bit of weight, but still dont feel confident enough to run outside or even on a treadmill. Every so often this knee gives out momentarily. I can rover, but it has been scary the couple times I have been going downstairs with a load of laundry.
Am I stuck with this forever, considering my age? I do squats and leg gursl to strengthen it-they havent helped a bit. Neither has calcium or glucosamine.
I just bought an elliptical which gives me a good workout with no issues. I can live with having to use that, but I miss running-even on the treadmill. Thanks for your thoughts.

Bud, without a physical evaluation it's hard to give you a concrete answer. However, if you look for my youtube channel you see videos of exercises (side-lying abduction, towel eater exercise, slow calf raises, and 1-leg sit to stand) that will benefit you. Often when we want to prevent the knee from having pain or giving out we need to focus on the joints above and below the knee.  The knee is the connector of our ankle and hip. Make sure to work all of the exercises in the videos that I suggested really well.  Within a week I would be surprised if you don't notice a significant difference. Will this make it so you can run again? I don't know for sure, but there's a chance. There is a good chance that you'll feel safer carrying laundry though.

Please let me know if you have follow-up questions or the success you have.
