Three hundred patients with expected primary total knee arthroplasty (TKA) without severe deformity (a fixed varus or valgus deformity greater than 20\u00b0) received fixed weight\u2010bearing (<jats:italic>n<\/jats:italic> = 150) or mobile weight\u2010bearing (<jats:italic>n<\/jats:italic> = 150) devices. Clinical, radiological, and quality of life outcomes were compared between the two groups at six\u2010month intervals for the first year, after which the comparisons were made annually for the next 4 years.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Both groups had similar baseline characteristics. Although there was significant improvement in both groups, there was no significant difference between the groups with regard to the means of the Knee Society Scores, which were 92 (SD: 12.1) for the fixed weight\u2010bearing device and 93 (SD: 14.2) for the mobile weight\u2010bearing device (n.s.) at the final follow\u2010up point. Radiographs showed that there was no significant difference in prosthetic alignment and no evidence of loosening. After TKA, the SF\u201036 score increased in both groups, but there was no statistical difference between the groups in quality of life at the final follow\u2010up (62 (12.2) vs. 64 (14.3), n.s.).
