简介：AbstractPurpose:This study was designed to compare the clinical efficacy of "8" and "0" wire fixation systems combined with double-head cannulated compression screws or Kirschner wires for the treatment of transverse patellar fractures.Methods:From September 2011 to September 2018, patients with closed transverse patellar fractures treated with a double-head compression screw or Kirschner wire were included and analyzed retrospectively. Patients with patellar fractures combined with distal femoral fractures, tibial plateau fracture or preoperative lower limb dysfunction were excluded. The patients treated with the "8" tension band wire fixation system and Kirschner wire were taken as Group A; those treated with the "0" fixation system and Kirschner wire were taken as Group B; those treated with the "8" fixation system and double-head cannulated compression screw were taken as group C; and those treated with the "0" fixation system and double-head cannulated compression screw were taken as group D. Six weeks and one year after the operation and every month from the third month after the operation until the fractures healed, an X-ray examination was performed to identify fracture healing. The time of fracture healing and postoperative complications of the four groups were compared. One year after the operation, knee function was evaluated by Bostman’s score.Results:During the study period, 168 patients with patellar fractures were treated by operations, and 88 patients were excluded because the fracture type did not meet the requirements or because there were combined fractures of the distal femur or tibial plateau. As a result, 80 patients were included in this study, 20 in each group. All the patients were followed up for an average period of 12.2 months. Compared with Group A, patients in Group D presented less postoperative discomfort in the prepatellar region, quicker fracture healing, less fixation failure and better postoperative knee function scores (all p < 0.05). The incidence of internal fixation failure in Group (B+D) was lower than that in Group (A+C) (p > 0.05).Conclusion:The "0" wire fixation system combined with a double-head cannulated compression screw seems to be more beneficial than the other three fixation systems for the treatment of transverse patellar fractures.

简介：运动评价髌(VISA-P)规模的BackgroundThe维多利亚式的研究所是过去常与膝盖骨的tendinopathy在运动员估计症状严厉的最条件特定的报导病人的结果措施。以前的探索因素分析被进行了评估规模维数，与不一致的结果，并且规模的因素结构仍然保持不清楚。现在的学习的目的是越过包括的sexes.MethodsThe学习用确定的因素分析(CFA)和测试测量不变性决定VISA-P规模的因素的结构有膝盖骨的tendinopathy的249个西班牙的运动员的一件便利样品。CFA被执行估计因素的有效性。假设1因素和2因素模型被测试。越过性的测量不变性用EQS6.1software.ResultsThe与几个合适的索引经由多组CFA被评估内部一致性系数0.74。几个CFA模特儿被检查，在为项目的错误，7和8被相关的1因素模型出现了可接受装入比较合适的索引(CFI)和goodness-of-fit索引(GFI)的术语统计(CFI=0.93；GFI=0.94；标准化根平均数平方residual=0.06；approximation=0.10的根均方差；90%信心间隔：0.08-0.13)。这个模型越过在为项目的错误，7和8被相关的VISA-P规模(VISA-P-Sp)的西班牙的版本的1因素模型表明了的sexes.ConclusionThe是不变的亲戚装入CFA。没有性偏爱，经由VISA-P-Sp获得的分数能在男人和女人之间被比较。进一步的研究应该并发地检验VISA-P规模和另外的单个分数的报导病人的结果措施。
