Knee Replacement Surgery ?

Just met with Ortho. Knees are pretty well shot. Bone on bone in both. Maybe 60% in left and 40% in right. Guess years of running in my former life, jumping rope, jits, and squatting heavy have taken their toll. I am only 53. I didn't think I would be in this position till I was in my 60's or later but nevertheless, here I am. Been hurting to walk for a while but kind of just grit and bear it. Still squat and do BJJ but knew that it was time to go see the Dr. However, I was actually shocked to see the x-rays. It looks bad.

So, the Ortho gave me options which the ice and PT stuff I already do. Shots seem like I would just be prolonging the obvious outcome so I have pretty well decided to do surgery on both knees. I will stagger them. Get one done and when about 70% do the other. Seems like a no-brainer surgery as long as I do my part on rehab. I was told the things that are probably over for me are squatting heavy, so it seems like that is finished. I used to love to do rope work but obviously quit that already for the most part. Just from knowing the toll jits does on knees I feel like doing that at a high level is also finished. Kinda bummed that lots of things I really love to do are over but I don't know if I can take much more walking like a gimp with bow legs.

Any advice from those that have done this before? Feels a little depressing. Doc did say I could play golf pain free so maybe I will just focus on my golf game moving forward.
