简介：AbstractPurpose:The poor prognosis in patients with floating knee injuries is mainly contributed to articular involvement (Fraser's type II). This study aims to evaluate and compare the functional outcomes among different Fraser's type II floating knee injuries after surgical management.Methods:Twenty-seven patients with Fraser's type II floating knee injuries (54 fractures) between September 2014 and December 2015 were enrolled prospectively in this study and were distributed according to Fraser's floating knee classification into three different groups as type IIA (ipsilateral femoral shaft and tibial intra-articular involvement, n = 11), type IIB (ipsilateral tibial shaft and femoral intra-articular involvement, n = 9) and type IIC (both femoral and tibial intra-articular involvement, n = 7). The differences among the groups were evaluated and compared. The functional outcomes of these injuries at one year were analyzed using Knee Injury and Osteoarthritis Outcome Score (KOOS) which covers 5 subscales of pain, other symptoms, activities of daily living, sports and recreation, and quality of life. The result was also compared with standardized age-sex matched healthy population using paired samples t-test.Results:All the patients were male, and the injury mechanism was solely roadside accident. The mean age was 29.8 years and injury severity score 17.9 (comparable in all the three groups). Most injuries were observed on the right side (20 cases, 74.1%). Based on paired samples t-test, the KOOS score of patients with Fraser's type IIA was found to be better than that of type IIB and type IIC. Compared with the reference age-sex matched control group, patients with Fraser's type IIB and IIC fractures had significantly lower mean score in all KOOS subscales (all p < 0.01). However, Fraser's type IIA only revealed significant difference regarding the subscales of activities of daily living (p < 0.0001), sports and recreation (p < 0.0001), and quality of life (p < 0.0001).Conclusion:The results of this study show that patients with Fraser's type IIA fractures had a better functional outcome as compared to those with type IIB and IIC fractures. This might be due to the open intra-articular involvement of the distal femur of the latter two fracture types.

简介：摘要目的：了解青光眼临床指南的质量现状，为中国青光眼指南使用推荐提供参考。方法：文献研究。使用指南研究和评估工具AGREE II对美国眼科学会指南（AAO-PAC、AAO-POAG、AAO-POAGS）、欧洲青光眼指南（EGS）、国际眼科协会青光眼指南（ICO）、亚太青光眼指南（APGG）以及中国原发性青光眼诊断和治疗专家共识（CG）进行质量评价。对评估所得的各领域得分采用均数±标准差进行描述，通过组内相关系数对评估的可靠性进行分析。结果：组内相关系数均大于0.9。范围和目的及清晰性的得分较高，其余4项得分相对较低。各项领域得分分别为84%±19%（领域1，范围和目的），37%±18%（领域2，参与人员），25%±25%（领域3，严谨性），90%±16%（领域4，清晰性），34%±10%（领域5，应用性），40%±34%（领域6，独立性）。AAO-POAGS各领域得分为99%、42%、61%、97%、41%、77%。我国2014年版CG的各领域得分分别为47%、4%、8%、57%、17%、0%。结论：在目前各国的青光眼指南中，AAO-POAGS最值得优先推荐，2014年版CG尚未达到AGREE II关于指南推荐的标准，未来中国的青光眼循证指南制定过程需更加透明化和严谨，参与制定人员组成需更加多元化。
