What symptom does shift appear after crural sprain 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: fracture and dislocation of the tegmental joint: usually in the process of dislocation, 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 by 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.

Third: subluxation of the knee: subluxation of the knee is usually caused by the fracture of the corresponding ligament structure of the knee. 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.
