Was told I needed microfracture surgery back in the early 2000's. Years of soccer and some basketball was the cause. Skipped the surgery though as I had heard it was quite painful and I wasn't pursuing a career playing sports. Now I'm 40 years old and my knees struggle. Hard for me to squat down and getting up off the floor can be painful. I have wondered what would they feel like if I had gotten. Just got back into playing indoor soccer and I feel some discomfort and the knees have no explosiveness, but that also could be my age and not related to needing surgery. I just use CBD before playing and I'm able to get around.
