### input:
Following 5 years of hip pain and 3 exploratory/cleaning operations I finally had hip resurfacing 2 years ago. All was well and I was pain free until I had knee realignment surgery. After the surgery I had a bad fall landing from the height of a chair directly onto the resurfaced hip. Since then I have had pain which is slowly getting worse. The hospital have x-rayed the joint and done an ultrasound and there is no fracture, no metal in the blood tests, no sign of inflammation / bursitis, no infection. I have had 6 months of strong painkillers and anti-inflammatory medication, 6 weeks of ultrasound therapy and physio and still it gets worse. I have pain when I try to lift my leg and if I lie flat in bed I have intense pain from the front of the hip radiating into the thigh. If I bend down and stand up there is a sensation of grinding which is very unpleasant and after walking a short distance I start to limp heavily and almost have to drag my leg. The pins placed in my knee are slightly visible and I have no sensation in the side of my lower leg, I asked if this could be the problem but have been told it s not an issue but I am hoping to get them removed soon just in case. The hip doctors seem to think it is just muscle ache from the realignment surgery and that it will just go so I feel that they are not taking my pain seriously, their only suggestion at the moment is taking stronger and stronger pain medications.

HelloI have studied your case in detail. The X-rays and tests are negative for fracture and no metal problem, means the pain may be muscular as your surgeon says. The operation may have been proper size of both femur head and socket implants since for 2 years you didn't get pain, there is no loosening or autolysis as not visible in x-ray. If you still have doubts, which is not wrong to have because of pain and restriction of movement which was not before, you may seek opinion at some other orthopedic center or surgeon. If something is wrong with alignment in knee implants, it is possible to have altered mechanics to account for discrepancy in was but pain doesn't explain-so presuming it to be muscular, take medicines as advised and visit for review to a new clinic of knee and hip surgeons best wishes
