<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi Doctor, I have an open wound on my knee that hurts when I move it.  <response>: Okay, for an open wound of the knee, we need to perform wound care management and complete a physical skin exam. We may have to suture the wound if its deep enough, and we may need to apply a splint to keep the knee stable. In severe cases, we may have to excise the wound. If needed, well refer you to a home health care service. Well also examine your foot to ensure there is no further injury.
