Osteoarthritis commonly causes knee joint effusion. It is usually caused by degenerative joint disease, and patients can undergo X-ray or MRI examinations to determine the exact condition. It's also important to avoid excessive joint movement and get adequate rest. Additionally, using some blood-activating and muscle-relaxing medications appropriately can yield better results and help alleviate pain.
