Radiostereometry is a precise method to evaluate implant migration as a surrogate marker for aseptic implant loosening and later revision. The aim of this prospective single-centre cross-sectional cohort study was to evaluate fixation of trapeziometacarpal cups using radiostereometry, report clinical and patient reported outcomes at 5\u2009year follow-up, and assess the complications and survival rate of the Moovis cup with up to 9\u2009years of follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Four-hundred and eighty-four conical press-fit dual-mobility Moovis trapeziometacarpal implants were inserted in 407 patients, with a mean age of 59\u2009years (range 43\u201380). Tantalum beads were inserted in the trapezium during index surgery. Radiostereometric images at 3\u2009weeks, 3\u2009months, 1\u2009year, 2\u2009years and 5\u2009years after the index surgery were used to measure cup migration. Clinical and patient reported outcomes were recorded for 5\u2009years. The cumulative implant survival until 9\u2009years was analysed using the Kaplan\u2013Meier method.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Cup migration was 0.28\u2009mm (95% CI: 0.25 to 0.32\u2009mm) total translation at the 3\u2009month follow-up and remained stable until the 5\u2009year follow-up. Females had 0.15\u2009mm (95% CI: 0.06 to 0.24\u2009mm) more cup migration (total translation) than males at the 5\u2009year follow-up. Grip strength, resting and activity pain, and Quick DASH score showed clinically relevant improvement at 1\u2009year and remained stable until the 5\u2009year follow-up. Medium-term patient satisfaction was 96%, and willingness to repeat the procedure was 96%. The 9\u2009year cumulative implant survival rate was 98% for cup removal owing to aseptic loosening and 87% for removal\/exchange of any implant component.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Stable cup fixation and high patient satisfaction until 5\u2009years combined with good 9\u2009year survivorship for Moovis press-fit cups favour its use in the treatment of trapeziometacarpal osteoarthritis. Although these results cannot be directly extrapolated to other trapezial cups, they suggest that similar press-fit conical trapezial cup designs may also provide good fixation and favourable clinical outcomes in the treatment of painful trapeziometacarpal joint osteoarthritis, in patients between the ages of 40 and 80\u2009years.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of evidence:<\/jats:title>\n                    <jats:p>Level II<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/17531934261459885","type":"journal-article","created":{"date-parts":[[2026,7,22]],"date-time":"2026-07-22T11:18:57Z","timestamp":1784719137000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["A five-year radiostereometry study of cup fixation and implant survival in 484 Moovis trapeziometacarpal arthroplasties"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4530-2075","authenticated-orcid":false,"given":"Maiken","family":"Stilling","sequence":"first","affiliation":[{"name":"Department of Clinical Medicine, Aarhus University, Aarhus N, Denmark"},{"name":"AutoRSA Research Group, Orthopaedic Research Unit, Aarhus University Hospital, Aarhus N, Denmark"},{"name":"Department of Orthopaedic Surgery, Aarhus University Hospital, Aarhus N, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1678-3612","authenticated-orcid":false,"given":"Torben","family":"B Hansen","sequence":"additional","affiliation":[{"name":"Department of Clinical Medicine, Aarhus University, Aarhus N, Denmark"},{"name":"Department of Orthopaedics, University Clinic for Hand, Hip and Knee Surgery, G\u00f8dstrup Hospital, Herning, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2742-7966","authenticated-orcid":false,"given":"Janni K","family":"Thillemann","sequence":"additional","affiliation":[{"name":"Department of Clinical Medicine, Aarhus University, Aarhus N, Denmark"},{"name":"AutoRSA Research Group, Orthopaedic Research Unit, Aarhus University Hospital, Aarhus N, Denmark"},{"name":"Department of Orthopaedic Surgery, Aarhus University Hospital, Aarhus N, Denmark"},{"name":"Department of Orthopaedics, University Clinic for Hand, Hip and Knee Surgery, G\u00f8dstrup Hospital, Herning, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,7,22]]},"reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"publisher","DOI":"10.1177\/1753193413481302"},{"key":"e_1_3_2_3_1","doi-asserted-by":"publisher","DOI":"10.3390\/jfb9010009"},{"key":"e_1_3_2_4_1","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-197759010-00004"},{"key":"e_1_3_2_5_1","doi-asserted-by":"publisher","DOI":"10.1177\/1558944718797341"},{"key":"e_1_3_2_6_1","doi-asserted-by":"publisher","DOI":"10.1177\/1753193420921307"},{"key":"e_1_3_2_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0749-0712(21)00761-7"},{"key":"e_1_3_2_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0304-3959(01)00349-9"},{"key":"e_1_3_2_9_1","doi-asserted-by":"publisher","DOI":"10.3109\/17453674.2015.1115312"},{"key":"e_1_3_2_10_1","doi-asserted-by":"publisher","DOI":"10.2519\/jospt.2014.4893"},{"key":"e_1_3_2_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2011.11.027"},{"key":"e_1_3_2_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.hansur.2015.08.002"},{"key":"e_1_3_2_13_1","doi-asserted-by":"publisher","DOI":"10.3109\/17453674.2013.765625"},{"key":"e_1_3_2_14_1","doi-asserted-by":"publisher","DOI":"10.1177\/1753193409355627"},{"key":"e_1_3_2_15_1","doi-asserted-by":"publisher","DOI":"10.2340\/17453674.2024.40709"},{"key":"e_1_3_2_16_1","doi-asserted-by":"publisher","DOI":"10.1177\/1753193420901435"},{"key":"e_1_3_2_17_1","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.K.00907"},{"key":"e_1_3_2_18_1","article-title":"Early migration of tibial components is associated with late revision: a systematic review and meta-analysis of 21,000 knee arthroplasties","volume":"83","author":"Pijls BG","year":"2012","unstructured":"Pijls BG, Valstar ER, Nouta KA, et al.
