Hello....I am 72 and have been living without a left hip joint for 2.5 years now. My original hip replacement became infected after 17 years resulting in necrosis, osteomyelitis of femur and pelvis. I am walking with a walker at home and crutches when I go out. I do daily exercises for strengthening and also ride an upright exercise bike. I find it easier than a recumbent bike. I can walk short distances in the home with no aide and can use one crutch pretty good. My good leg does most of the work and about 9 months ago I tore the meniscus on that knee, but it's getting better and I continue with strengthening. I'm in Michigan and we just got back from a 10 day camp trip in our camper and fishing in our pontoon. I have very little pain. I'm happy to answer any questions you may have. Wishing your husband all the best.....Cindy
