To know if the healing of your knee wound is normal, it is recommended to clean the wound with water and mild soap without alcohol. Remove debris by rinsing the cut with water, keep the wound as dry as possible, and change the dressing more frequently if it becomes wet from oozing liquid. Avoid using Polysporin quick-heal, as it contains unnecessary ingredients for wound care. Watch out for signs of infection such as heat, swelling, spreading redness beyond the cut, and increasing pain. If these signs are present, seek medical advice.
