膝关节

Methods Thirty New Zealand and, rabbits underwent unilateral anterior cruciate ligament transection were random divided into two groups.

30只6个月龄新西兰大白兔行右膝关节前交叉韧带切断术。

Two defects of articular cartilage were made in the trochlear groove of each new zealand rabbit.

二、动物体内实验部分：将48只双侧膝关节软骨缺损的3月龄新西兰兔动物模型随机分为四组。

Chondrocytes from femur trochlear cartilage of eight porcins were isolated and cultured to 4th passage. These cells were counted and divided into 4 groups: monolayer culture group for 1w, polylayer culture group for 0w , 1w and 2w.

3.8头猪膝关节软骨标本经上述方法分离得到的软骨细胞传代培养第四代后，分别进入4个组别：单层培养1周组、复层培养0周组、1周组和2周组。

INTERVENTIONS: A full-thickness defect in articular cartilage was made on the femoral trochlear surface by a drill of 5 mm in diameter and 3 mm in depth. Rabbits were allocated into filling group(type Ⅱ collagen sponge was grafted into left keen joint defect) and control group(right knee joint defect site was set as control) according to random number table.

干预：在股骨滑车面钻孔为直径5 mm、深3 mm的全层关节软骨缺损，按随机数分为填充组(左膝关节缺损部位植入Ⅱ型胶原海绵)和对照组(右膝关节缺损部位作为空白对照)。

We included 60 patients who developedmoderate-to-severe pain within 1 h after knee arthroscopy undergeneral anesthesia.

我们采纳了60名在全麻下行膝关节镜的患者。他们术后1小时内都发生中到重度的疼痛。

Results The follow-up time was from 5 to 30 months with an average time of 12 months. All fractures had unioned excellently without displacement, no complications of knee laxities and instabilities were found.

结果 随访5~30个月（平均12个月），所有患者骨折均愈合良好，未发生骨折移位、膝关节松弛或不稳定等并发症，关节功能恢复满意。

In cases of varicose veins, short periods ofsitting in postures such as Vajrasana may be beneficial.

几乎所有的坐着的体式都需要臀部和膝关节有良好的灵活性。

Exposure of the ankylosed knee can be difficult.

暴露僵直粘连的膝关节是很困难的。

Method］From January 2003 to January 2007, VVC arthroplasty was performed in 18 complex cases (19 knees),among them there were 11 cases with valgus knee,7 cases (8 knees) with ankylosed knee.

［目的］回顾性分析内外翻限制性假体（varusvalgus constrained implant，VVC）在复杂初次膝关节置换中的应用经验，总结VVC假体使用的适应证及临床效果。

According to the surface electromyogram to statistically analyse IEMG and knee joint in different phases, we can find the relationship among the main work muscle in swinging of hurdle step, the cooperative muscle of crura muscle in doing act, the change of angle in pressing and touching down, and skill action.

根据表面肌电图，对IEMG及不同阶段膝关节角度进行统计分析。结果发现，在跨栏步摆动腿动作中的主要工作肌，在完成相应动作的肌肉发力顺序，在完成动作过程中下肢肌肉表现出来的协作肌和对抗肌以及蹬地和着地时角度变化跟技术动作的关系。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down
