What symptom does knee shift have
summary
Knee displacement is a very common disease in modern society. The knee joint is an important part of human joints. However, those who know it should be familiar with it. It is the support point of our actions. Standing, squatting, walking and so on all rely on the knee joint. If the knee joint is damaged, such as knee dislocation, knee arthritis and so on, it will directly affect our normal activities, So what are the early symptoms of knee dislocation? Let's get to know it with me!
What symptom does knee shift have
First, dislocation of knee joint (total): according to the relative position of tibial condyle and distal femur, it can be divided into: ① anterior dislocation of knee joint; ② Posterior dislocation of knee joint; ③ Lateral dislocation of knee joint; ④ Medial dislocation of knee joint; ⑤ Rotation dislocation of knee joint. The frequency of dislocation direction of knee joint is in the following order: anterior dislocation, posterior dislocation, lateral dislocation, rotational dislocation and medial dislocation. The incidence of anterior dislocation of the knee is twice that of posterior dislocation, and medial dislocation is about 1 / 8 of anterior dislocation.
Second: subluxation of the knee: subluxation of the knee is usually caused by the fracture of the corresponding ligament structure of the knee, and the tibia moves forward, backward or rotates. Some authors do not advocate subluxation as a classification of knee dislocation, and suggest that subluxation should be regarded as a kind of knee instability.
Third: fracture and dislocation of the tegmental joint: usually in the process of dislocation formation, the impact of the femoral condyle on the tibial condyle can lead to the fracture of the tibial condyle, and the fracture displacement will be caused with the continuous external force; Of course, muscle contraction at the attachment site also plays an important role. Clinically, the avulsion of the bone mass at the ligament attachment point can also be regarded as joint dislocation with fracture.
matters needing attention
I believe we all know the importance of knee joint for us. There are more and more knee joint diseases in our daily life, and there are many friends lying on the hospital bed for a long time due to knee joint dislocation. Therefore, I need to remind you that you must protect your joints and avoid injury.
