Male Aged 52 just received THR 6 days in. exeter hip implanted by NHS in UK right side. Left is 6 yr old BHR implanted by same surgeon. So now in excellent position to comment on differences between THR vs BHR as new bilateral. First; UK NHS recently instructed by national institute of clinical excellence (NICE) to no longer supply any MOM hips. My new hip metal on ceramic old technology, so far recovery so much easier than BHR, hopefully will continue, 6 days no crutches at home, one crutch on walks, minimal pain. With BHR was in much more pain and greater swelling, but still mobile.
Cause of hip failure is DDH (developmental dysplasia of hips) diagnosed 04, so probably did well to last that long, especially after 20 +Years in military.
Bad news is BHR maybe looking suspect, shady area on x rays under femoral head, but so far Ions normal and scan OK, but need to be watchful.
Will see how recovery of THR goes vs BHR (although memory will be factor)
