膝关节

A retrospective study design was conducted by using chart reviews to choose patients who received unilateral primary total hip and knee replacement (International Classification of Diseases, Ninth Revision, Clinical Modification procedure code of 81.51 and 81.54) in two medical centers between 2001 and 2004. Patients were excluded from the study if they had had a bilateral in the same admission, fractures, previous arthroplasty surgery complication, bone cancer, pathological fractures, infection and hemophiliac.

Concrete details are:(1) The Clap skates elevate the flexibility through the link structure of the "hinge", thus change the malpractice of traditional push-off process which mainly depends on the power of the hipbone and the knee, and thus obstruct the use of the power of ankle.

具体表现为：（1）Clap式冰刀通过"铰链"连接结构，提高了踝关节的自由度，改变了传统冰刀在蹬冰过程中主要发挥髋、膝关节的力量，而难以利用踝关节力量的弊端，在增加做功环节的同时又加大了膝关节的工作范围。

We reported 5 cases with intra-articular synovial hemangioma of the knee in order to improve diagnosis and treatment of intra-arfieular synovial hemangioma of the knee.

The stude announces that their changeable regular of the center of gravity level speed in supporting phase is falling in tne first cushioning phase. When their center of gravity's vertical lines pass their heels and their knee joints go on extended contraction ,their center of gravity level speed has extended .the reason is that their angles have passed the heels and their swinging legs' kenn joints have swinging the front of their bodies. Its power originates the swinging leg's forward active swinging and the decurtation contraction of hip joints 、ankles of the supporting legs.the swinging leg shows "the calf's active backward swinging"before its landing impact,the skill affects the loss of center of gravity level speed when the swinging leg lands.they enlarge their trunks' forward-landing impact phase ,it can decrease the center of gravity level speed's loss after landing and impel the center of gravity level speed to pass the supporting spot quickly.

两人缓冲阶段身体重心水平速度变化规律是在体前缓冲阶段呈下降趋势；当身体重心垂线超过脚后跟后，在膝关节继续缓冲做退让收缩的情况下身体重心水平速度开始加大，原因是踝关节在最大缓冲时身体重心已移过支撑面及摆动腿膝关节已做体前摆动，主要动力来源于摆动腿的积极前摆和支撑腿髋、踝关节的克制性收缩；在摆动腿下压着地前期是大腿积极下压小腿随大腿的积极下压顺势向前下滑摆，在摆动腿下压着地后期表现出"小腿积极回摆"技术，对减小着地时的水平速度损失、加大向前用力都有积极影响；适当加大摆动下压着地阶段躯干的前倾角度，有利于减少着地时相的速度损失和有利于身体重心较快的移过支撑点；缩小后蹬结束后的后伸动作幅度，有利于减小腾空时间。

Whichever approach you take, move the shinbone just enough to straighten the knee so that it no longer curves back, but not so much that the knee bends forward.

不管你用哪种方式，移动小腿骨恰到好处地伸直膝盖，不再让膝关节往后弯，但也不要太高以免膝关节向前弯。
