My ceramic right hip will be 3 years old in May, I am 69. My surgeon said I would be able to do everything I wanted to, I would not break it, so I ran from 6 weeks. I race 5k most Saturdays and am planning a 48 mile challenge in the mountains this summer.
On the other hand, my sister-in-law had a new hip a year ago, cemented cup and stem, and her surgeon says she must avoid impact activities like running, climbing and netball – but expects the device to last 39 years i.e. to age 90. She is still having some soft-tissue/muscle problems..
I doubt a second doctor will give you the all-clear to run, it will be up to you, but I would bet you are OK to try.
