My uncle was fit and fine 3 years ago before being told he needed a hip replacement. He went and got it done, and hasn’t been the same since. He never regained strength in his hip, the doctors then found other other things wrong with him and decided he needed spinal surgery - he’s now essentially house bound and has become depressed.
This seems to be a trend. Every person I know who's done hips or knees never recovered, went on to have multiple surgeries to fix problems which appeared to be caused by the first surgery, and then they always found extra things the person just needed to have done right away or else.
