If it is an ordinary surgical wound, and if regular disinfection and medication changes can be achieved after the surgery, and if the wound is not infected, the soft tissue edema around these surgical wounds can be completely eliminated in about 5-7 days, but if it is edema after fracture surgery, this swelling can be eliminated only in about 2 weeks or even 4 weeks after the surgery. However, in the case of edema after fracture surgery, this swelling can take up to 2 weeks or even 4 weeks to resolve. If the surgery damaged the lymphatic vessels or lymph nodes, there may be a long-term obstruction of lymphatic flow, and the swelling may not go down for a long time.
