Knee issues

[M-technik-3]

my right knee is loosing cartilage around me knee seems to be long time of year as I was a runner and my service job had me on my feet doing leg work.

I stand alot at my three CNC machines at work and have a stool I use and a knee brace now to prevent movement.

I have tried heat and ice routines and elevate it when possible but not sure how to slow it. I am active and I love to hike walk and cycle. It's impacting it and I have gained 7 pounds this year, First time I have been over 200 lbs on average for any length of time. Minus career change or surgery any other options
