In loose implants (group 1), bone formation activity compared to the contralateral healthy femur was 261 %. In the proximal part of the femur bone formation was increased by 253 % one week after revision (group 2) and did not normalize within 1 year. In the distal region it decreased to normal after one year. In the second revision group DXA showed decreased bone mineral density at 6 and 24 months (group 3).\n                  <\/jats:p>\n                  <jats:p>The PET technique provided evidence of bone healing despite osteolysis and prosthetic loosening which continued after revision.
