临沂保安公司提醒您膝关节害怕剧烈运动

  很多健美运动员,但稍有不慎就会受伤,膝盖是最脆弱的部位之一。解放军总医院骨科副主任医师王长江表示,膝关节是人体最大、最复杂的屈伸关节,它就像一个承重体,在运动时承重整个上半身和大腿。
  Many bodybuilders are injured if they are not careful, and the knee is one of the most vulnerable parts. Wang Changjiang, deputy director of orthopaedics of PLA General Hospital, said that the knee joint is the largest and most complex flexion-extension joint of the human body. It is like a load-bearing body, which carries a upper body and a thigh during exercise.
  膝关节附近有前后交叉韧带、内外侧支韧带和髌韧带。是限制作用,韧带内没有髓神经纤维,人体韧带运动受紧张,感觉由神经引入,此时引起相应的肌肉反射性收缩,以限制膝关节活动,保持关节稳定,称为韧带肌肉反射。韧带的限制作用可以与相关肌肉协同作用,也可以与韧带组合协同作用。如果肌肉控制失败,只能达到韧带的机械限制。第二是指导。交叉韧带与半月板由韧带纤维组织连接,在膝关节内形成“8”字形结构,共同维持膝关节的稳定性,引导膝关节向一定方向有规律地运动。
  There are anterior and posterior cruciate ligaments, medial and lateral collateral ligaments and patellar ligaments near the knee joint. Ligaments have no myelinated nerve fibers. Ligaments are tense in motion and sensation is introduced by nerves. At this time, it causes corresponding muscle reflex contraction to restrict knee joint activity and maintain joint stability, which is called ligament muscle reflex. Ligament restriction can be synergistic with related muscles or ligament combinations. If muscle control fails, only the mechanical limitation of the ligament can be reached. The second is guidance. The cruciate ligament and meniscus are connected by ligament fibrous tissue, forming an "8" shaped structure in the knee joint, which jointly maintains the stability of the knee joint and guides the knee joint to move regularly in a certain direction.

  临床上,内侧副韧带损伤是最常见的损伤,主要是由瓣膜和胫骨外旋引起,导致韧带拉伤。最常见的是运动员突然改变方向和变速(如足球、篮球、羽毛球)。如果冲击力引起膝关节胫骨外翻(通常伴有胫骨外旋),则容易引起内侧副韧带损伤。内侧副韧带损伤20% ~ 70%伴有其他韧带损伤。例如内侧副韧带深附着于内侧半月板,5%的内侧副韧带损伤伴有内侧半月板撕裂。此外,前交叉韧带损伤合并内侧半月板损伤也较为常见,主要是由于膝关节过度伸展或外翻所致。

  In clinic, medial collateral ligament injury is the most common injury, mainly caused by valve and tibial rotation, leading to ligament injury. The most common is that athletes suddenly change direction and speed (such as football, basketball, badminton). If the impact force causes tibial valgus of the knee joint (usually accompanied by tibial rotation), it is easy to cause medial collateral ligament injury. Medial collateral ligament injuries ranged from 20% to 70% with other ligament injuries. For example, the medial collateral ligament is deeply attached to the medial meniscus, and 5% of the medial collateral ligament injuries are accompanied by tearing of the medial meniscus. In addition, anterior cruciate ligament injury combined with medial meniscus injury is more common, mainly due to overextension or valgus of the knee joint.

  异常和膝盖外翻,更多的是外侧和内侧副韧带损伤,但可能前后交叉韧带损伤,它通过抽屉可以判断测试:平放在床上,膝盖弯曲90度,患者抓住脚固定,患者胫骨侧抱着膝盖,小腿拉,如在侧胫骨向前大于5毫米是正的,连续前不稳定。
  Abnormal and knee valgus, more lateral and medial collateral ligament injury, but may be anterior and posterior cruciate ligament injury, it can be judged by drawer test: flat on the bed, knee bending 90 degrees, patients grasp the foot fixed, patients with tibia side holding knee, leg pull, such as tibia forward more than 5 mm is positive, continuous anterior instability.
  急性膝关节韧带损伤发生后,应立即停止一切活动,减少出血。立即用冷水冲洗受损部位或在患处敷上冰块止血。然后盖上绷带,用力按压以防止肿胀。如果韧带完全断裂或怀疑有骨折的并发症,必须咨询医生进行进一步的检查和治疗后,压缩和敷料。经过24~48小时后,损伤部位的内出血已停止,这时可用温热毛巾热敷或用消肿按摩并促进血液吸收。俗话说“断骨断肌100天”,前交叉韧带一般很少单独受伤,多伴有内侧和外侧副韧带或半月板损伤,做膝关节核磁共振检查即可确诊。如果前交叉韧带断裂或部分断裂,需要手术缝合。术后4 ~ 6周应行外固定。取出外固定物后应积极进行康复训练。
  After acute knee ligament injury, all activities should be stopped immediately to reduce bleeding. Immediately rinse the damaged area with cold water or apply ice to the affected area to stop bleeding. Then cover the bandage and press hard to prevent swelling. If ligament rupture is complete or complications of fracture are suspected, a doctor must be consulted for further examination and treatment, compression and dressing. After 24 to 48 hours, the internal bleeding in the injured area has stopped. At this time, warm towel hot compress or massage with detumescence can be used to promote blood absorption. As the saying goes, "100 days of broken bones and broken muscles". Anterior cruciate ligament is rarely injured alone. Most of them are accompanied by medial and lateral collateral ligaments or meniscus injuries. The diagnosis can be confirmed by magnetic resonance imaging of the knee joint. If the ACL is ruptured or partially ruptured, surgical suture is required. External fixation should be performed 4 to 6 weeks after operation. Rehabilitation training should be actively carried out after removal of external fixtures.
