In 2010, the Articular Surface Replacement (ASR) was withdrawn because of a high failure rate. In 19 ASR femoral components, the mean micromovement over the first two years after implantation was 0.107\u00a0mm (sd 0.513) laterally, 0.055\u00a0mm (sd 0.204) distally and 0.150\u00a0mm (sd 0.413) anteriorly. The mean backward tilt around the x-axis was -0.08\u00b0 (sd 1.088), mean internal rotation was 0.165\u00b0 (sd 0.924) and mean varus tilt 0.238\u00b0 (sd 0.420). The baseline to two-year varus tilt was statistically significant from zero movement, but there was no significant movement from one year onwards. <\/jats:p><jats:p> We conclude that the ASR femoral component achieves initial stability and that early migration is not the mode of failure for this resurfacing arthroplasty. <\/jats:p>","DOI":"10.1302\/0301-620x.94b10.29030","type":"journal-article","created":{"date-parts":[[2012,9,27]],"date-time":"2012-09-27T01:57:24Z","timestamp":1348711044000},"page":"1344-1350","source":"Crossref","is-referenced-by-count":9,"title":["Early micromovement of the Articular Surface Replacement (ASR) femoral component"],"prefix":"10.1302","volume":"94-B","author":[{"given":"J.
