Times vary a lot. Until the surgeon has gotten into you and sees how much he has to cut to sort things out, the answer you are asking for isn;t known. It also depends a lot on how the surgeon puts you back together. The old way with stitches is a slow heal. I had a mesh put in and was on the trainer in 10 days and back on the road not long after. But I rode gingerly for quite a while.
Edit: Oh, I was 47.
