Video of transverse stress test and inspection method

Lateral pressure test method: the patient lies on his back, the affected knee is straight and the quadriceps femoris is relaxed. The doctor fixes the knee joint with one hand and holds the ankle joint with the other, and makes the knee joint passively varus or valgus with relative force. Under normal circumstances, there is no lateral movement and no pain.

Lateral compression test is a method to check whether the medial and lateral collateral ligaments of knee joint are damaged. For example, being hit by external force or sprained knee joint can easily lead to the injury of medial and lateral collateral ligaments of knee joint.

During the examination, the patient's leg should be straightened, and the operator should break the inside and outside of the knee joint by hand. If there is pain inside and outside the knee joint, it means that the collateral ligament is damaged. It is best to examine the knee joint by magnetic resonance imaging to determine the specific degree of injury, and then perform plaster external fixation or surgical treatment to anastomose the broken ligament.

Significance of lateral extrusion test

Lateral pressure test is mainly aimed at the physical examination of knee ligament injury. Clinically, there are sprains and pains in the medial and lateral knee joints. Judging the tightness of medial collateral ligament or lateral collateral ligament of knee joint and the degree of pain during physical examination by lateral compression experiment, the severity of ligament injury can be roughly inferred.

Generally, a doctor holds the outside of the knee joint with his left hand and the inside of the ankle joint with his right hand, and then checks the characteristics of the painful part of the medial collateral ligament in the process of palm opposition. When examining the lateral collateral ligament, the action is just the opposite. In addition to this physical examination, a magnetic resonance vibration examination is needed to judge the specific characteristics of ligament injury more clearly.
