Thirteen months after my hip replacement, everything is tickety-boo. Despite rotten weather and lots of moving about I've been able to add more and more kms to the hip:
May - 49 km
June - 79 km
July - 63 km (including the first cycling)
August - TBD, but shooting for 100 km. (13 so far)
No sign of troubles with the right hip. So that's good.
Strange thing though: the weight hasn't changed a bit.
