Full rigid question - for those who have a replaced hip

Background 20 months ago I broke my hip while riding my mountain bike on a simple trail, dust on hard clay me fall down and go boom. I broke my hip, and due to surgical error needed a revision which was done in April. My flexion after the first hip was terrible, I'm hopeful this time will be better, but I expect it will never be as good as my natural hip :( . I'm not certain that I will have the ROM to ride a full rigid bike on the trail again. I know I'm a very small subset of this group, but those who have a el-fako hip what do you ride?

Just for context I have been riding a 1986 Diamondback Apex, I bought it new, Like me It's kinda beat up but I love this bike.
