Objective To investigate the motor function of knee and provide range of normal value for rehabilitation of knee function.

目的 通过调查正常男性青年膝关节的运动参数，为膝关节的运动功能康复提供依据。

Methods One hundred patients with osteochondritis dissecans in the knee proved by arthroscopy and clinic performed MR examination with SPIR-3D-FFE-T1WI sequence.

回顾性分析100例经膝关节镜及临床随访证实的膝关节剥脱性骨软骨炎MRI影像资料。

The high-frequencyultrasound may be a examining method for peripheral osteophytosis basing on it' s high sensitivity for detecting osteophyte of lateral margin.

4。高频超声因对膝关节上下关节缘骨赘突起的敏感性较高，可以作为膝关节周围性骨质增生的一种检查方法。

Ligaments were very important to provide stability of knee joints, but some dancing motions take shearing force to knee joints and caused ligaments overstretch.

同时，闭锁运动链的运动型态也促进了踝关节及足部的本体知觉。膝关节的韧带在支持膝盖的稳定度上扮演了非常重要的角色，但是有些舞蹈动作会在膝关节形成一个剪力进而造成了韧带的过度牵张。

According to patient's condition, different type of tendon transplant to reconstruct ACL by press fit technique should be selected carefully.

结果］98例患者得到随访，膝关节稳定，功能恢复良好。按照膝关节疗效评定标准，优88例，良6例，可4例，优良率85.7%。

BACKGROUND: MRI is a gold standard for imaging diagnosis of knee joint disease, but it cannot accurately quantitate effusion of knee.

背景：MRI是目前膝关节疾病影像诊断的金标准，但还不能对膝关节积液准确定量。

The mean range of motion was improved from preoperative 84°(40°-95°) to postoperative 104°(80°-120°); the mean preoperative Knee Society Scores were increased from preoperative 39 scores (10-67 scores) to 87(10-100), and the function was improved from 38 scores (0-60 scores) to postoperative 76(20-100). Alignment was obtained in 31 knees, with well localized femoral and tibial prostheses. The tibial prosthesis of 1 case developed inadequate retroversion; of 2 cases remained 2°-3° inversion; non-progressive radiolucent zone was found between tibial prosthesis and bone interface of 1 case.

膝关节活动度从置换前平均84°(40°~95°)增加到置换后平均104°(80°~120°)，膝关节评分从置换前平均39分（10~67分），提高到随访时平均87分（10~100分），功能评分从置换前平均38分（0~60分）提高到随访时平均76分（20~100分）。31膝获得肢体的良好对线，股骨及胫骨假体位置良好。1例胫骨假体后倾不足，2例胫骨假体残留2°~3°内翻，1例胫骨假体与骨组织界面存在非进展性透亮带。

AIM: Patients' satisfaction after total knee arthroplastys greatly depended on pain remittence of knee joint and the maximal range of motion.

目的：全膝关节置换手术后患者的满意度很大程度上取决于膝关节疼痛的缓解程度以及关节的最大活动度。

Objective To discuss the outcomes of rotatory hinge prosthesis in limb-salvage surgery for osteosarcoma around the knee.

目的 探讨旋转铰链型人工膝关节在膝关节周围骨肉瘤保肢术中的临床应用效果。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
