(1) Slight: ligament strain, but no fracture. There is pain and swelling, but there is no functional loss or joint instability.

(2) Moderate: the ligament is partially broken, with moderate pain and swelling at the injured part, and some joint activities are reduced and unstable.

(3) Severity: complete ligament rupture, severe swelling and bleeding, and obvious loss of joint mobility and stability.

If the ligament is pulled and torn, it is best to treat it with Jiegu Powder, which can promote the absorption of local tissue exudates as soon as possible, relieve pain quickly, eliminate swelling and help complete healing. Gansu Baiyin
