Hi,
My dad has had a hip replacement about 6 years ago.
I don't own a Morgan but I do have a fairly low convertible car.
After the operation dad was not allowed to bend his leg past a certain angle so didn't go in my car for a few months, but now has no issues. I think the issue is that until all the tendons and muscles have recovered there is a high chance of dislocation.
Dad was telling me that there is a new method of transplant surgery that involves putting the replacement in from the front and the recovery is much quicker.
I think dad was about 75 when he had the surgery, for his 80th birthday he wanted a new pushbike, we went shopping and he ended up with a nice Merida carbon fibre 22speed ultegra. Then we entered a 210km charity ride called around the bay (Melbourne Australia and goes around the bay). He was pretty tired but did finish the whole 210km ride.
He can't run anymore but he can ride a bike just as well if not better than he could.
I am currently in bed with a dvt and I think that the pain is pretty much the same as dad's hip replacement,I just hope that the thinners work soon and the blood can start to flow.
Good luck with the operation.
Chris
