Well it’s worth knowing what hips the trust finance. How many athletes has the surgeon got back to competitive/recreational activity? What is the hospital trust guidance on ‘younger hip patients’. Why is something like a Furlong Evolution Ceramic on ceramic not being considered? What rules you out of having such an implant?
What is the long term data on the hip you are being given? How many are still in situ at 20 years follow up? How many are revised? What actually IS he considering for you?
All relevant questions that would inform you why running is not advised after the op. I’ve followed up about 30 hip patients who have had a modern uncemented’hip for life’ and all were back running and cycling with the blessing of their surgeon within 3 months!
