Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a leg knee joint supporting device for sports medicine. Background Art

[0002] Medial collateral ligament injury of the knee is a common knee injury in physical labor and sports. When the knee joint is subjected to sudden violent force, especially when the knee is subjected to sudden valgus or rotational force in the extension or flexion position, the medial collateral ligament of the knee will be injured.

[0003] In order to determine the extent of the medial collateral ligament injury of the knee joint, clinicians need to take a knee tension radiograph. In the process of taking a knee tension radiograph, the patient's leg needs to be valgused with the assistance of family members or medical staff. It is difficult to control and maintain the valgus angle of the knee joint during the process of artificial valgusing of the knee joint, which is not conducive to the filming process.
