Of 975 papers identified, 34\u00a0trials were eligible for data extraction and meta-analysis comprising 4754 patients (6861 knees). We found no statistically significant differences between the two designs in terms of the incidence of radiolucent lines, osteolysis, aseptic loosening or survival. There is thus currently no evidence to suggest that the use of mobile-bearing designs reduce polyethylene wear and prolong survival after total knee replacement. <\/jats:p><jats:p> Cite this article: Bone Joint J 2013;95-B:1057\u201363. <\/jats:p>","DOI":"10.1302\/0301-620x.95b8.31310","type":"journal-article","created":{"date-parts":[[2013,8,1]],"date-time":"2013-08-01T09:17:21Z","timestamp":1375348641000},"page":"1057-1063","update-policy":"http:\/\/dx.doi.org\/10.1302\/crossmark-policy","source":"Crossref","is-referenced-by-count":23,"title":["Is there reduced polyethylene wear and longer survival when using a mobile-bearing design in total knee replacement?"],"prefix":"10.1302","volume":"95-B","author":[{"given":"Y.","family":"Zeng","sequence":"first","affiliation":[{"name":"West China Hospital, Department\rof Orthopaedic Surgery, West China Medical\rSchool, Sichuan University, 37#\rGuoxue Road, Chengdu, Sichuan\rProvince 610041, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B.","family":"Shen","sequence":"additional","affiliation":[{"name":"West China Hospital, Department\rof Orthopaedic Surgery, West China Medical\rSchool, Sichuan University, 37#\rGuoxue Road, Chengdu, Sichuan\rProvince 610041, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Yang","sequence":"additional","affiliation":[{"name":"West China Hospital, Department\rof Orthopaedic Surgery, West China Medical\rSchool, Sichuan University, 37#\rGuoxue Road, Chengdu, Sichuan\rProvince 610041, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Z.
