    什么是半月板?半月板对膝关节软骨起保护作用.因为半月板是通过增加接触面积来承受股骨和胫骨之间的负荷,而且可以随膝关节的活动改变其形状,减少接触应力,以保护关节面.而且能够使身体向下传达震荡,为膝关节内的缓冲装置.


    What is the meniscus meniscus? Protective effect on articular cartilage of the knee. Because the meniscus is by increasing the contact area between the femur and tibia to bear the load, but also with the knee joint activities to change its shape, reduce the contact stress, in order to protect the joint surface. And that causes the body to convey down concussion, buffer device of knee joint.


    什么会引起半月板损伤呢?主要的外因有两种,①撕裂性外力损伤,②研磨性外力损伤,为运动员、搬运工、矿工等人的多发病.半月板的典型损伤原因为膝关节在屈曲位置的伸直活动中,同时伴有超过生理限度的内旋或外旋损伤所致.


    What is the cause of meniscus injury? There are two main external factors, the tearing force injury, the grinding force injury, the populationhere athletes, porters, miners et al. Typical causes of injury of knee joint meniscus is in flexion position extension activities, accompanied by over pronation or supination injury physiological limits.


    半月板损伤病因有哪些?西郊骨科医生来解答!


    What are the causes of meniscus injury? To answer the Western doctor working in the Department of orthopedics!


    1.内侧半月板损伤的病因病理膝关节屈曲位,股骨在胫骨上作强度的内旋运动,在半月板后移的基础上并向关节移动,如此可能使半月板边缘的附着部分撕裂.当半月板处于此异常位置时,膝关节的突然活动,将其后中部挤压在股骨内髁与胫骨平台关节面之间而发生半月板体部撕裂伤,此种裂伤可能为纵形或斜行.


    Etiology and pathology of knee flexion 1 medial meniscus injury, femoral internal rotation motion intensity in the tibia, based in the meniscus moved and the joint movement, so may make the meniscus edge attachment partially torn meniscus. When in this abnormal position, sudden activity of knee joint, thereafter between central extrusion condyle and the articular surface of tibial platform in the femur and the body of the meniscus laceration laceration, such as longitudinal or oblique.


    2.外侧半月板损伤的病因病理正常膝关节稍有外翻,外侧半月板负重较大,若为先天性盘状半月板,长期受关节面的研磨也可发生损伤.


    Etiology and pathology of normal knee joint 2 lateral meniscus injury slightly valgus, load lateral meniscus is larger, if congenital discoid meniscus, articular surface for grinding can also be damaged.


    3.失力症状失力症状为半月板损伤的常见症状,特别是陈旧性损伤,亦可能为半月板损伤仅有的症状.多发生在病人上、下楼梯、跳跃或其它相似的运动时失力.其特点是发生在走凹凸不平的道路,夜间走路,突然转身或下蹲等类似的动作时.病人失力的感觉为.突然感到关节内有物滑动",或"感觉关节内有响动"等,并突然感觉膝关节有向内或向外不稳或软弱现象.


    Common symptoms of stress symptoms 3 failure symptoms of meniscus injury, especially the old injury, may also the only symptom of meniscus injuries. Failure occurred in the patients, down the stairs, jumping or other similar movement. Its characteristics are occurred in the rugged road walk, walk at night, suddenly turned around or squatting and other similar actions. The patient lost the power of feeling. Suddenly feel joint with slide ", or" feel "joint ring, and suddenly felt knee inward or outward instability or weak phenomenon.


    4.膝关节肿胀和积液半月板被嵌在股骨髁及胫骨髁之间以前,势必将半月板的边缘附着部撕伤,以使半月板向关节中间部分移动.由于关节周围韧带及滑膜的损伤,势必使关节发生积液.因此,如果损伤后膝关节未发生积液,则半月板损伤的可能性极小.


    4 knee joint swelling and effusion of meniscus is inserted between the femoral condyle and tibial condyle before, is bound to meniscal edge insertion avulsion, to move to the middle part of meniscus joint. Because of joint ligament and synovial injury, is bound to make the joint effusion. Therefore, if the injury of knee joint without effusion, minimal the possibility of meniscus injury.


    5.股四头肌萎缩股四头肌萎缩是任何膝关节损伤后均可发生的症状之一.半月板损伤后,并多次反复发作,使股四头肌萎缩屡次加重.


    The 5 unit four biceps wilt shrink four head muscle atrophy is any knee injury can occur symptoms of meniscus injury, and repeated attacks, the stock four myo atrophy has increased.


    6.膝关节交锁症状膝关节交锁症状可发生在受伤的当时,或受伤之后,是诊断半月板损伤很可靠的证据之一.因此,在讯问病史时应特别注意此点..一般关节交锁症状多发生在膝关节伸直至130~140度时.如仅有伸直困难,或不能完全伸直,不能认为是交锁,必须同时伴有弹响.


    The 6 locking knee symptoms locking knee symptoms can occur in the injured at the time, or after the injury, is one of the diagnosis of meniscal injury is reliable evidence. Therefore, in the interrogation of history should pay special attention to this point. The general locked joint symptoms occur in knee extension to 130~ 140 degrees. If only straight difficulties, or cannot complete unbend, cannot be considered to be locked, must be accompanied by snapping.
