Hi Sunbun,
I (Anne) had a total hip replacement at the end of October, 2013. I was 59 at the time. I followed all the required surgeon and physio instructions. I also did a lot of exercises in the pool which I think helped with my recovery.
My husband and I were planning to walk our first
Camino Frances in August, 2014. My surgeon reviewed me in March, 2014 and said I could start training walking for the Camino from then. We completed more than 800kms in training before heading off to start the Camino. We started the Camino as planned from St Jean Pied de Port on 22nd, August, 2014 and made it to Santiago de Compostela on 2nd, October, 2014, without any issues, taking three rest days along the way. This was the start of our long distance walking and we were hooked. So from my experience ten months is a long enough recovery period but be guided by your surgeon.
My husband has completed all our Caminos with both hips replaced twice.
I walk with hiking poles and we now don't carry heavy backpacks anymore.
Buen Camino,
Anne & Pat
