Swollen legs need to be considered according to the specific circumstances of the treatment, mainly cold compresses, plaster immobilization, surgery and other ways to deal with. Cold compresses should be applied immediately for acute injuries to reduce local bleeding and swelling. 72 hours later, local physiotherapy, such as local microwave or ultrashort wave physiotherapy, can be used to promote tissue healing. If there is partial ligament laxity or injury, complete ligament rupture with ankle instability, etc., it can be immobilized by cast for 4-6 weeks or surgically. If the fracture mass enters the joint, it can be surgically cut and repositioned and immobilized, or the ligament can be repaired directly and immobilized in a cast for 3-4 weeks after surgery. For repeated ligament injuries and ankle instability, autologous tendon transfer or allogeneic tendon grafting can be used to repair and rebuild the stability of the ankle joint in order to protect the ankle joint. When you have a swollen broken leg, it is recommended that you seek medical attention in a timely manner, follow the doctor’s instructions for relevant examinations, clarify the cause with the help of the doctor, and carry out targeted treatment or therapy.
