A total of 27 patients (28 knees) awaiting unicompartmental knee arthroplasty were randomly allocated to have the operation performed conventionally or with the assistance of the Acrobot. The primary outcome measurement was the angle of tibiofemoral alignment in the coronal plane, measured by CT. Other secondary parameters were evaluated and are reported.<\/jats:p>\n                  <jats:p>All of the Acrobot group had tibiofemoral alignment in the coronal plane within 2\u00b0 of the planned position, while only 40% of the conventional group achieved this level of accuracy. While the operations took longer, no adverse effects were noted, and there was a trend towards improvement in performance with increasing accuracy based on the Western Ontario and McMaster Universities Osteoarthritis Index and American Knee Society scores at six weeks and three months. The Acrobot device allows the surgeon to reproduce a pre-operative plan more reliably than is possible using conventional techniques which may have clinical advantages.<\/jats:p>","DOI":"10.1302\/0301-620x.88b2.17220","type":"journal-article","created":{"date-parts":[[2006,1,24]],"date-time":"2006-01-24T13:48:46Z","timestamp":1138110526000},"page":"188-197","source":"Crossref","is-referenced-by-count":281,"title":["Hands-on robotic unicompartmental knee replacement"],"prefix":"10.1302","volume":"88-B","author":[{"given":"J.","family":"Cobb","sequence":"first","affiliation":[{"name":"Imperial College London, Department of Orthopaedics, Charing Cross Hospital, Fulham Palace Road, London W6 8RF, UK."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Henckel","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Middlesex Hospital, Mortimer Street, London W1T 3AA, UK."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"Gomes","sequence":"additional","affiliation":[{"name":"The Acrobot Co.
