膝关节

Objective Knee osteoarthritis may induce arthrogenous muscle inhibition and muscle weakness.

目的：膝关节骨关节炎（knee osteoarthritis，膝OA ）可造成关节源性肌肉抑制（arthrogenous muscle inhibition，AMI）和肌肉软弱。

Objective To explore the diagnostic value of indirect magnetic resonance arthrography in detecting meniscus tears of the knees.

目的 探讨弥散法MR膝关节造影诊断半月板撕裂的临床应用价值。

MRI has essentially replaced arthrography for the evaluation of internal derangement of the knee.

对评价膝关节内紊乱，MRI已基本上取代了关节造影。

MRI of 36 cases with acute cartilage injury of knee confirmed by arthroscopy and arthrostomy were retrospectively analyzed, with emphasis on articular cartilage and subchondral lesion.

分析其中36例经关节镜或手术证实关节软骨损伤患者的膝关节MRI所见，着重观察关节软骨和软骨下骨的改变，并与关节镜和手术结果对照分析。

Mri of 36 cases with acute cartilage injury of knee confirmed by arthroscopy and arthrostomy were retrospectively analyzed, with emphasis on articular cartilage and subchondral lesion.

分析其中36例经关节镜或手术证实为关节软骨损伤患者的膝关节mri所见，着重观察关节软骨和软骨下骨的改变，并与关节镜和手术结果对照分析。

Osteoarthritis models were established by anterior cruciate ligment transection in the model group and treatment group; while arthrotomy was performed in sham operation group.

对照组只行右膝关节切开术，模型组和治疗组行右前交叉韧带切断术，以建立兔膝关节炎模型。

There was apparent interspace between repaired tissue and surrounding normal tissues. The results indicated that: 1 Although autogenic cartilage obtained from patella in knee joint is limited, chondrocytes cultured in vitro could be regulated by some growth factors, therefore sufficieng and well-phenotype chondrocytes could be harvested to construct tissue engineering implants for transplantation. 2 It showed well therapeutic efficacy with the method of repair in our research.

实验结果表明：①自体膝关节髌骨来源的软骨虽有限，但在体外单层培养时应用生长因子对其进行调控，能为自体关节软骨缺损的移植治疗提供数量充足的、表型良好的软骨细胞以用于构建组织工程移植物；②本实验中所应用的修复方法治疗效果良好，能较有效地克服和解决目前在临床上所用的自体关节软骨细胞移植修复关节软骨缺损时所存在的软骨细胞容易丢失等问题。

A piece of cartilage chip was cut from an adult rabbit patella in lateral border, and autogenic chondrocytes were isolated、culture、subcultured in medium complemented with bFGF and TGF-βin order to regulate their differentiation and proliferation.

在成年兔自体膝关节髌骨外侧缘取部分软骨，分离、传代培养软骨细胞，同时应用bFGF和TGF-β控制其分化和增殖。

The healing process and histological behavior of the tendon transplantation group were similar with those of the autografting group, however, which was better by liquid nitrogen after program freezing than by -80℃ deepfreezing.

结论经程序冷冻液氮保存和-80℃深低温保存方法冻存的兔异体髌腱重建膝关节交叉韧带后愈合过程和自体韧带移植重建过程相似，但程序冷冻液氮保存法优于传统的-80℃深低温保存法。

Objective To discuss the use of autologous blood transfusion in total knee replacement.

目的 探讨预存式自体输血在全膝关节置换术中的临床应用。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
