Given the predictive value of early RSA migration patterns at the 2-year mark for identifying implants at risk of aseptic loosening, we hypothesize that the Delta-TT cup will demonstrate good stability at the 10-year postoperative mark. Besides, it is hypothesized that migration of Delta TT-cups is comparable between ceramic and polyethylene liners.\n\nThe primary objective of this study is to measure the long-term stability of the Delta TT cup, combined with either a ceramic or cross-linked polyethylene liner, by means of RSA at 10-years postoperatively.\n\nSecondary objectives are to measure long-term stability of the H-MAX S stem, by means of RSA at 10-year postoperatively. Furthermore the study aims to measure implant survival rates and patient-reported outcomes for both the Delta-TT cup and H-MAX S stem, comparing outcomes between the ceramic and polyethylene group.",[76],"Hip Dislocation","2025-03-12",{"date":79,"type":80},"2025-03-14","ACTUAL",{"date":82,"type":80},"2024-10-10",{"date":84,"type":72},"2029-05-01",{"name":5,"class":6},1]
