I'm sorry to hear about your knee injury. It’s good that you have already cleaned the wound with Savlon and applied Soframycin cream, which is effective in preventing bacterial infections in minor cuts and scratches.

Here are some additional steps you can follow for proper care:

• Keep the wound clean and dry: After applying the cream, cover the scratch with a sterile bandage or gauze to protect it from dirt and further injury.
• Change the dressing daily: Replace the bandage at least once a day or whenever it becomes wet or dirty.
• Watch for signs of infection: These include increased redness, swelling, warmth, pain, pus, or fever. If you notice any of these, please consult a doctor promptly.
• Avoid scratching or picking at the wound: This can delay healing and increase the risk of infection.
• Continue using the antiseptic cream as directed: Usually, applying it 1-2 times daily until the wound heals is sufficient.

If the wound does not improve in a few days or worsens, it is important to see a dermatologist or a general physician for further evaluation.

For any severe pain, spreading redness, or if you develop fever, seek immediate medical attention.
