A total of 961 hips were included. Cortical ratio between inner and outer cortices at the centre of the plug was measured on routine postoperative follow-up moments. Median follow up of all 3 hospitals was 3.5\u2009years (1.4\u20137.3). The primary outcome was evidence of osteolysis (i.e. the difference in cortical ratio [CR]) on anteroposterior (AP) radiographs at final follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Progressive osteolysis was found around the PEG\/PBT cement restrictor represented by a significantly increasing cortical ratio (\u0394CR 0.067 (95% CI, 0.063\u20130.071). Distance from tip prosthesis to plug and size of the plug were found to be independent factors in predicting increased cortical ratio.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Our multicentre cohort shows increase of cortical ratio around the PEG\/PBT cement restrictor which progresses over time.
