2017 is when I broke my hip in a mountain bike accident; I was 49. It all happened so fast... in the blur I remember the surgeon suggesting total hip replacement saying a repair would be problematic in a few years. I had the total hip replacement and riding the indoor bike for physical therapy within a few weeks. However, I took 6 long months off from outdoor riding, but did much walking during that time. I did start riding that fall, and about 500 miles/month the next year. The riding was challenging at first, but rebuilt muscle lost in traditional surgery.
Just ride, it is great therapy.
