Perform Therapeutic Arthrocentesis to Drain Intra-articular Effusion

1. Consult with an orthopedic specialist to confirm the presence of significant joint effusion via physical examination or ultrasound imaging.

2. Prepare the knee joint site using strict sterile technique to prevent the introduction of pathogens into the joint capsule.

3. Utilize a needle and syringe to aspirate the excess synovial fluid, blood, or inflammatory exudate, typically targeting the suprapatellar recess where fluid accumulates.

4. Send a sample of the aspirated fluid for laboratory analysis if an underlying infection or crystalline arthropathy, such as gout, is suspected.

5. Apply a sterile compression bandage post-procedure to minimize fluid re-accumulation and facilitate the immediate restoration of knee flexion range of motion.
