Surgical Incision Problems Generally, the incision for debridement surgery is over the original joint replacement incision, so it does not cause much trauma. Under normal circumstances, the wound heals in two weeks after surgery. However, if the skin or soft tissue condition is particularly poor, such as the presence of skin necrosis or heavy scarring, the wound will take longer to heal at this time. In addition, the wound healing time after debridement treatment is also longer compared to the first surgery. This is because normally, the tissue in the body is structured layer by layer from the skin to the joints. However, the tissue structure that has been operated on is no longer layer by layer, but a large scar block, which has a reduced ability to fight infection and poor blood circulation. When surgery is performed again, the soft tissues in the skin are “aggravated”, so recovery is slower. Bacterial culture is usually performed before or after surgery to find out what kind of bacteria has infected the skin. Generally bacterial cultures take 5 to 7 days, and some special types of bacteria, such as tuberculosis, require extended cultures of 14 to 21 days. However, some patients report that no bacteria are found after bacterial culture is performed, why is this the case? First, not all bacteria can be cultured under the current conditions, and some more specific bacteria may not be cultured for the time being; second, antibiotic treatment has been started when the specimen is taken, then most of the bacteria in the joint may be inhibited or killed by antibiotics at this time, which will reduce the detection rate of cultured bacteria. Therefore, it is recommended that it is best to perform bacterial culture before applying antibiotics; third, the time of culture is not enough. For bacteria that are not cultured according to the routine, the doctor should communicate with the microbiologist and possibly extend the culture time to perhaps culture the bacteria. After postoperative re-infection problems are treated with debridement, all bacteria in the joint can be eliminated; for some specific types of bacteria, 80% to 90% of them can be removed after debridement treatment, and the residual bacteria can be eliminated all together with targeted antibiotics after surgery. However, the joint prosthesis is still a foreign body to the patient, and even after debridement treatment, there is a risk of reinfection. However, if after the first infection, the surgeon follows strict principles to manage the infection and remove all bacteria from the joint, there is usually no need to worry unduly about the infection until the skin wound has healed.
