No difference in clinical outcome between fixed- and mobile-bearing TKA: a meta-analysis.

摘要: To compare the clinical and radiographic results of fixed-bearing mobile-bearing total knee arthroplasty (TKA). We searched PubMed, Medline, Embase, Cochrane Central Register Controlled Trials, Google Scholar databases from 1966 to January 2012. No language restriction was applied. Reference lists all selected articles were hand-searched for any additional trials. Trial quality assessed using modified Jadad scale. Two authors independently extracted data eligible studies, including study design, participants, interventions, outcomes (Knee Society Score, range movement, radiolucent line, patient preference, walking support, pain score, complications). The fixed-effects or random-effects models with mean differences risk ratios continuous dichotomous variables, respectively. A 24 studies involving 2,799 patients identified in this analysis. Meta-analysis showed lower score (OR, 0.66, 95 % CI 0.46, 0.94) TKA than TKA. There no significant difference between two treatment groups regarding Knee Score (SMD, −0.17, CI: −0.60, 0.26), movement −0.05, −0.63, 0.53), line 1.03, 0.74, 1.44), preference 1.15, 0.82, 1.61), support 1.07, 0.68, 1.70), complications 0.85, 0.59, 1.21). available evidence suggested that there except score. Regarding relevance, less incidence could be advantage selecting II.
