However, before its widespread use it is necessary to clarify contraindications and assess the complications. This requires a larger study than any previously published.<\/jats:p><jats:p>We present a prospective multicentre series of 1000 cementless OUKRs in 881 patients at a minimum follow-up of one year. All patients had radiological assessment aligned to the bone\u2013implant interfaces and clinical scores. Analysis was performed at a mean of 38.2\u00a0months (19 to 88) following surgery. A total of 17 patients died (comprising 19 knees (1.9%)), none as a result of surgery; there were no tibial or femoral loosenings. A total of 19\u00a0knees (1.9%) had significant implant-related complications or required revision. Implant survival at six years was 97.2%, and there was a partial radiolucency at the bone\u2013implant interface in 72\u00a0knees (8.9%), with no complete radiolucencies. There was no significant increase in complication rate compared with cemented fixation (p = 0.87), and no specific contraindications to cementless fixation were identified.<\/jats:p><jats:p>Cementless OUKR appears to be safe and reproducible in patients with end-stage anteromedial osteoarthritis of the knee, with radiological evidence of improved fixation compared with previous reports using cemented fixation.<\/jats:p><jats:p>Cite this article: Bone Joint J 2013;95-B:181\u20137.<\/jats:p>","DOI":"10.1302\/0301-620x.95b2.30411","type":"journal-article","created":{"date-parts":[[2013,1,30]],"date-time":"2013-01-30T17:18:30Z","timestamp":1359566310000},"page":"181-187","update-policy":"https:\/\/doi.org\/10.1302\/crossmark-policy","source":"Crossref","is-referenced-by-count":98,"title":["Cementless fixation in Oxford unicompartmental knee replacement"],"prefix":"10.1302","volume":"95-B","author":[{"given":"A.
