膝关节

It's reliable to resume the ability of knee joint by arthroscopic-assisted using dual-beam four-stranded quadrupled hamstrings tendon and suture button plate to reconstruct ACL .

关节镜下利用双骨道双束腘绳肌肌腱和缝线钢板，重建ACL韧带是一种可恢复膝关节功能的可靠方法。

To simulate the friction/slip boundary conditions between the skin and liner, the automated surface-to-surface contact was used.

并在考虑行走过程中外力和惯性载荷的同时，考虑了膝关节刚体位移和残肢弹性变形之间的耦合。

Results: Nerve roots and ganglions, carotid arteries , articular cartilages , ligaments and articular plates were visible clearly.

结果：45例PROSET成像中，分别清晰显示相应脊神经根、颈动脉血管、膝关节的关节软骨和交叉韧带、颞颌关节的关节盘。

Barbie's shoulder, thigh hip joints are mobile, hidden joints can do 60-degree knee bend, head can be rotated, it put a lot of beautiful shape.

If you are heavy-set or suffer from knee problems, cranks can be very beneficial in preventing pressure from falling on the knees when you are cycling on a stiff slope.

如果你是重设置或患有膝关节的问题，曲柄可以是非常有益的预防压力落在膝盖当你在激烈的自行车斜坡。

Knee joint muscle plays a more notable role than hip muscle does in increasing vertical velocity of the body center of mass and enlarging the angle of take-off.

在增大人体重心垂直速度和重心的腾起角方面，膝关节肌较之髋关节肌都具有更为显著的作用。

The parameters were processed with SPSS for Windows12.0, and analyzed with repeated-measures ANOVA(α=.05).Results and Discussion:When the backpack load percentage during stair-down walking reaches 10%, knee landing angle, hip angle displacement, and vertical displacement of the center of gravity all have significant difference（pConclusion: Backpack load percentage has influence on human biomechanical performance during stair-down walking.

结果与讨论：下阶梯背重率达10％时，膝关节著地瞬间角度、髋关节角位移、重心垂直位移均达到显著差异(p＜。05)；当背重率达20％时，垂直分力与其产生时间、最大负荷率、踝关节肌肉力矩与角劲度亦达到显著差异(p＜。05)，此时人体必须透过增加踝关节角位移机制来降低垂直地面反作用力和最大负荷率及延后垂直峰值产生时间，藉以减少地面反作用力对人体所造成的冲击；而重心垂直位移也受到背重的影响而增加，以上均显示背重对人体下阶梯时下肢的负荷与影响。

Knee Joint Tilting Mechanism:Tilting Occurs at the Front or at the Knee Joint Position of the Chair Seat,and This Mechanism Supports Different Tilting Positions When the User Lean Backwards or Forwards

足膝平衡倾仰机关：此机关置于座位前端或接近足膝关节处，当使用者在不同位置倾仰时，此机关能提供适当的支持

Result: 98 cases comminuted patellar fracture were bone union. The better rate of knee joint was 96.9%, There's good joint function.

结果：治疗髌骨粉碎性骨折98例，骨折均获得骨性愈合，膝关节功能好，优良率96.9%。

Patients with knee osteoarthritis find that use of elastic knee sleeves gives them partial pain relief and a greater sense of joint stability.

护膝对於某些膝关节退化病人而言，具有减轻疼痛、增加关节稳定度的功能。

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。
