The median postoperative Hospital for Special Surgery score improved from 56 (range 32\u201377) to 91 (range 64\u2013100) points, but median range of motion did not change from 120\u00b0 (range 50\u00b0\u2013135\u00b0) to 120\u00b0 (range 85\u00b0\u2013135\u00b0). Complications occurred in 16 cases (4%), and included postoperative polyethylene dislocation and intraoperative tibial condylar fracture, while five knees (1%) required revision surgery due to mechanical reasons. The overall prosthesis survival rate was 91% at 12 years. Although the LCS mobile\u2010bearing knee system has theoretical advantages in terms of wear and loosening, the problem of polyethylene dislocation, intraoperative tibial fracture, and radiolucent lines should be solved for long survival. The clinical relevance of this study is that the LCS system provided good clinical and survival results.<\/jats:p>","DOI":"10.1007\/s00167-010-1166-5","type":"journal-article","created":{"date-parts":[[2010,6,15]],"date-time":"2010-06-15T13:04:40Z","timestamp":1276607080000},"page":"1345-1351","source":"Crossref","is-referenced-by-count":12,"title":["What have we learned from LCS mobile\u2010bearing knee system?"],"prefix":"10.1002","volume":"18","author":[{"given":"Woo\u2010Shin","family":"Cho","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery Asan Medical Center Ulsan University College of Medicine 388\u20101\u00a0Pungnap\u2010dong, Songpa\u2010gu 138\u2010736 Seoul Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoon\u2010Seok","family":"Youm","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery Ulsan University Hospital Ulsan University College of Medicine 290\u20103\u00a0Jeonha\u2010dong, Dong\u2010gu 682\u2010714 Ulsan Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sung\u2010Chan","family":"Ahn","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery Asan Medical Center Ulsan University College of Medicine 388\u20101\u00a0Pungnap\u2010dong, Songpa\u2010gu 138\u2010736 Seoul Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dong\u2010Wook","family":"Sohn","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery Asan Medical Center Ulsan University College of Medicine 388\u20101\u00a0Pungnap\u2010dong, Songpa\u2010gu 138\u2010736 Seoul Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2010,6,16]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.74B2.1544958"},{"key":"e_1_2_6_3_1","volume-title":"Statistical methods in medical research","author":"Armitage P","year":"1994"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199005000-00030"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003086\u2010200211000\u201000008"},{"key":"e_1_2_6_6_1","first-page":"84","article-title":"Twenty\u2010year evaluation of the New Jersey LCS rotating platform knee replacement","volume":"15","author":"Buechel FF","year":"2002","journal-title":"J Knee Surg"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003086\u2010200107000\u201000008"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199011000-00027"},{"key":"e_1_2_6_9_1","first-page":"147","article-title":"New Jersey low contact stress knee replacement system.
