Loosening of the Charnley hip. Radiographic analysis of 102 revisions.
This retrospective study was based on 102 Charnley hip arthroplasties that underwent a revision operation. Radiographs of hips with loose prosthetic components were compared with those with firm components. Migration and tilting of the socket and subsidence and varus shift of the stem were associated with loosening.
