A broken knee can be treated in the following ways to speed up the healing process: 1. The area must be debrided as soon as possible. It is recommended that the patient go to the emergency department of a level II or higher hospital as soon as possible after discovering a skin break around the knee joint and ask the doctor to help debride the wound. At this time, if the doctor deems it necessary, sutures may also be applied to speed up the healing process. 2. Patients should follow the doctor’s instructions, return regularly for medication changes, and observe the healing process of the wound. In addition, patients must pay attention to the protection of the wound during this period, not to touch the wound with their hands, not to expose the wound or water. 3, for some wounds with less exudate and no infection, you can apply epidermal growth factor gel on the surface to promote the healing of the epidermis. 4, patients must keep the brake during treatment, because this part of the knee joint will often cause the skin to be stretched due to activity. The skin is often stretched due to the activity of the knee joint, which is not conducive to the healing of the skin wound, so during the treatment period, it is best to keep the patient braked, rest, and do not do strenuous activities involving the knee joint.
