I have had my bi hip replacement now for 11 years. Last year I was still working hard on the farm up and down banks with ease. This year it is all together different The pain is in the lower part of the leg implants, it is making my balance bad as I am not sure if my leg will stand me if I am off balance. I am not sure what to do, I was expecting to get at least 20 years from the op I am now 70 and still have heaps of work to do.
