While RLL in only one zone did not predict loosening (<jats:italic>p<\/jats:italic>\u2009=\u20090.337), RLL present in two or more zones showed correlation with loosening (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). Risk factors associated with loosening were a higher age at the time of revision surgery (<jats:italic>p<\/jats:italic>\u2009=\u20090.030) and the number of zones with RLL (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). The glenoid component was loose in 39.0% of the cases; 5.5% of the glenoid components with RLL were stable. Nevertheless, the presence of RLL was highly associated with loosening (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001, Phi 0.603). A longer time between implantation and revision correlated with loosening of the glenoid component (<jats:italic>p<\/jats:italic>\u2009=\u20090.046).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>While RLL do not predict loosening of the implant in general, occurrence in more than one zone correlates with loosening.
