Patients are usually allowed to have water after 3 days of stitch removal, and for incisions involving joint sites, water is usually allowed after 5-7 days of stitch removal. Due to the many factors that affect the healing of the patient’s incision, such as age, type of disease, body type, incision length, and incision site, there is variation in stitch removal and healing time. Most patients’ suture pinholes were basically healed 3 days after stitch removal, but due to more activities in the joint area, there was a possibility that the suture pinholes were not healed 3 days after stitch removal, and water exposure could easily cause pinhole infection. Since the healing time of the incision is short and the healing strength of the incision is low when the patient is 3 days after stitches are removed, it is possible to rinse and shower at this time, but not to take a bath or rub to prevent the incision from cracking again. Patients should try to maintain a relatively dry and sterile environment after the incision is removed, prohibit smoking and alcohol consumption for 1 month, avoid sweating or sauna for 6 months, and consult a professional doctor to assess the healing of the incision before getting wet.
