What should be noted after knee joint aspiration (knee water removal)?

After knee joint aspiration (knee water drainage), the following points should be noted to promote recovery and avoid complications: 1. Rest and ice application: Immediately stop activities and rest the knee. Apply ice packs to the knee for 15 to 20 minutes each time, repeating 3 to 4 times daily, to reduce swelling and pain. 2. Maintain knee stability: Individuals with severe injuries may use bandages or braces to stabilize the knee, and should avoid bending or twisting the knee to maintain its stability. 3. Wound care: Keep the area around the wound dry and clean to prevent infection. Additionally, do not remove the compression bandage prematurely; follow the doctor's instructions regarding timing for removal. 4. Balanced diet and nutrition: Eat more protein- and vitamin-rich foods, such as eggs, milk, and vegetables, to enhance the body's immunity. 5. Regular follow-up: As fluid may accumulate again after aspiration, regular follow-up visits are recommended to monitor the condition.
