简介：AbstractAnterior tibiofemoral dislocation after total knee arthroplasty is an extremely rare and serious event. Amongst English-published papers, we found only 15 relevant cases, 3 of which presented vascular complications. This manuscript aims to present a 77-year-old woman with a TC-Plus (Smith & Nephew) cruciate-retaining type in first time of knee prosthesis, who suffered an anterior tibiofemoral dislocation and were admitted to our hospital. The clinical management and outcome were evaluated. Furthermore, a review of literature was performed. We concluded that early detection and surgical intervention of vascular injury is the key in the survival of the limbs. If there is still knee instability after acute recovery, it seems that revision surgery with constrained total knee arthroplasty can bring about good clinical and functional results.

简介：AbstractPurpose:The treatment and outcome of tibial stress fractures concomitant with knee osteoarthritis (OA) are complicated. The aim of this study was to evaluate the functional and radiological outcome of total knee arthroplasty with long tibial stem as a treatment for patients having knee OA and tibial stress fracture.Methods:Patients who were diagnosed to have proximal tibia stress fracture along with knee OA at our institution between June 2013 and November 2018 were included in our study. All patients underwent total knee arthroplasty with long tibial stem. Preoperative and postoperative functional assessments were done according to range of movement of the knee joint, knee society score and knee injury and OA outcome score. Descriptive analysis was carried out by mean and standard deviation for quantitative variables, frequency and proportion for categorical variables.Results:Twelve patients were included in the study. All patients were found to have stress fractures in the proximal half of tibia and extra-arthrosis. Four patients had non-union/delayed union, and 8 patients had acute fractures. The average preoperative range of movement was 88.1°, which improved to 116.3° at 3 months following surgery. It was found that the fracture has healed in all cases. Mean knee society score improved from 32.9 preoperatively to 89.3 at 1 year follow-up. Knee injury and OA outcome score improved from a mean score of 28.3 preoperatively to 81.1 at 1 year follow-up.Conclusion:Stress fractures can occur in the proximal tibia in patients with knee OA. Total knee arthroplasty with tibial stem provides a suitable solution for both conditions. Additional plating or bone graft is unlikely to be required.

简介：客观：到从膝系带的文化成纤维细胞房间并且到学习这些房间的生物特征。方法：前面的十字形的系带(ACL)和从新西兰白兔子的中间的并行的系带(MCL)的房间在vitro是有教养的。骨胶原的细胞的生长和表示被分析。而且，一在里面vitro创伤闭合模型被建立，ACL和MCL房间愈合被比较。结果：为所有这些房间的最大的生长与Dulbecco的家被获得修改的鹰与10%胎儿的牛的浆液补充的媒介，而是RPMI1640和火腿是媒介不是合适的维持这些房间的F12。从新西兰白兔子的ACL和MCL房间的形态学在vitro是相似的，但是MCL房间变得比ACL房间快。两种房间类型在我由ACL房间生产了打III的大杂烩类型的文化，而是比率生产了骨胶原的类似的数量比由MCL房间生产了高。创伤闭合试金证明在在损害以后的36个小时，在ACL文化创造的没有房间的地区被ACL房间部分占据；相反，在MCL文化的受伤地区被房间几乎完全盖住。结论：尽管从新西兰白兔子的ACL细胞和MCL细胞在文化在形态学显示出类似的外观，细胞的生长和象在vitro愈合一样的骨胶原的生物化学的合成是显著地不同的。在在vitro的房间的二种类型的内在的性质的这些差别可能在vivo贡献这些系带的微分愈合潜力。
