It is the number one reason for knee and hip replacement surgery in the United States.

这是数量的原因之一膝关节和髋关节置换手术在美国。

Results: The innervation pattern of the study was similar to that of Horner's.

Learn to straighten your knees with full extension of your legs but without hyperextension.

学习通过完全伸展你的大腿来伸展你的膝关节，但不超伸。

Hyperextension of the knee is when the top of the shinbone moves back further than the bottom of the thighbone.

膝关节超伸，是当胫骨的顶端向后移动，超过了大腿骨底部。

And finally, if your quads are untrained and/or weak (unfortunately true for many students new to yoga), these muscles will not contract enough to prevent hyperextension and help protect the knee.

最终，如果你的股四头肌没用受过训练和/或比较弱（很不幸的是很多瑜伽的新练习者往往都是这种情况），那股四头肌不会足够地收缩以防止超伸和帮助保护膝关节。

Results: MR examination of bone contusion were mostly less than two weeks, but a few patients were longer than one year: STIR, TIWI were more sensitive lesion detection series in hone contusion (100% and 95.7%). Bone contusion mostly occur at knee, and lesions mainly distributed in the margin area of articular (69.8%), in superior portion of vertebral body(74.l%). Bone contusion following-up showed a line-like hyperostosis and osteosclerosis in contusion area. Histological manifestations of bone contusion were local trabecular micro fractures, edema, hemorrhage and injury of fat tissue.

结果：1多数骨挫伤MRI检查在两周内完成，少数病人时间超过1年；2检出骨挫伤敏感的MRI序列为STIR及T1W/I（100%及95.7%）；3膝关节是骨挫伤的好发部位，病灶主要分布于骨边缘区(69.8%)，在脊柱主要分布于椎体上缘终板下(74.1%)；4骨挫伤影像随访提小病变区出现线状骨质修复，骨髓水肿吸收；5骨挫伤病理为骨小梁显微骨折，骨髓水肿、出血和脂肪损伤。

Objective To study the methods and effects of vascularized fibular combined with ilium graft after tumor extended resection for giant cell tumor of bone around knee.

目的 探讨吻合血管的腓骨、髂骨联合移植治疗膝关节周围骨巨细胞瘤扩大切除的方法及疗效。

Background: Normal anterior cruciate ligamentis an essential indicator of integral knee function.

背景：正常的前十字韧带是完整膝关节功能的重要指标。

Objective:To explore the innervation of knee joint and the possibility of neurotomy to treat the arthronalgia of knee joint.

目的：为膝关节疼痛的诊断及手术治疗提供局部神经支配的解剖形态学基础。

The experimental conclusion determined that if the knee joint angle can be kept at 140-150 in the buffer jump at various liftoff heights, and the coax joint as well as the knee joint can be larger than 170 at the instant liftoff, an optimal jump can then be achieved.

以上实验结果予以讨论后获得以下结论：苏翊伦选手在不同跳跃高度之起跳动作，若缓冲期间起跳脚膝关节角度能维持在140度？

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%.
