I had the same issue. My knee pain was so intense I was unable to sleep. I went with Regenexx stem cell and PRP method. All aren’t the same. My Doc injected my Femur, Tibia and meniscal cartilage. It takes about 10 weeks to feel totally back to normal with no pain at all. I was cycling and swimming two weeks post op, 3 months to start running again. You should look it up. Thumbs up here!
