Congrats on your progress! I had a couple of sports injuries in my late 40's I almost agreed to a meniscus repair and a buddy of mine just said "don't let them cut you unless the pain is unbearable". Thankfully my knee healed up nicely on it's own.
After that I kept on playing on hard courts for another 7 years, and suffered through several shoulder, foot, and knee injuries. The last knee injury hit me at age 55, I could barely walk for 2-3 months even and a cortisone shot only helped for about 2 weeks. I was deathly afraid I screwed up my knee so bad it was going to require knee replacement surgery. Once again I listened to my friend and waited it out and six months later I was a lot better. So much so that I went on to play one final hardcourt season.
Thank god my friend told me to hold off on any surgery I probably would be way worse off today if I let them cut me. For anyone considering surgery I strongly suggest BLIND 2nd and 3rd opinions.
