Because the knee is in the part of the joint, the stitches are removed later than other parts of the body. Generally the knee stitches are removed in about 2 weeks, but the specific time, should be determined by the size of the wound wound healing situation to determine the specific removal time. For cases where the wound healing is relatively smooth, it can be removed at once in about 2 weeks. For the wound healing is not particularly smooth or not completely healed even to 2 weeks of time can not be removed at once can choose to intermittent removal. 2 weeks or so after the intermittent removal, after 2-3 days interval change of medication, if the wound has been further healed, you can further remove the sutures, using a phased removal method. If the wound is not healing well, or even if there is an infection, it may be necessary to remove the sutures at an early stage, and it may even be necessary to remove the infected lesion, especially for wounds that have a reaction to the sutures, and these people have a rejection reaction to the sutures that rejects foreign bodies. For this group of people, it is recommended to remove the sutures at an early stage, and to carry out wound treatment to avoid wound infection. At present, for many sutures are absorbable, for such sutures can not be removed, usually the absorbable sutures can be absorbed by themselves in 6-8 weeks after the wound is closed, and the sutures that leak to the outside of the skin will fall off on their own, there is no need to remove them.
