Pros of Draining Knee – The List

1. One of the pros of draining the knee is that when fluid builds up in the knee due to an injury or medical condition. Draining the knee can help reduce swelling, improve the range of motion, and relieve pain. It can also help with the healing process. Draining the knee is a relatively straightforward procedure, with minimal risks and a short recovery time. It is often recommended as the first line of treatment for knee effusions, before attempting more invasive treatments.

2. Draining the knee joint can be an effective way to reduce pain and pressure in the joint. The process involves expelling the fluid that has built up in the knee, which can cause pain and stiffness. By removing the fluid, the joint can move more freely which can reduce discomfort and pain. This can also help to improve the range of motion, allowing for increased mobility.

3. One of the biggest advantages of draining a knee is the quick recovery time. While other more invasive treatments can take weeks or even months to fully recover from, draining a knee can often be done in a single day. This allows the patient to resume their daily activities as quickly as possible. Furthermore, the relatively short recovery time means that the patient will be able to return to their daily activities and sports with a minimal amount of time lost.

4. One of the major pros of draining a knee is that it reduces swelling in the joint. The procedure usually helps to relieve pressure and pain by removing the excess fluid that has built up in the knee. This can be especially beneficial for those with knee conditions such as arthritis, as the reduced swelling can improve joint mobility and reduce pain. It can also be beneficial for those who have suffered a knee injury, as it reduces the risk of further damage to the joint.

5. One major benefit of draining the knee is that it can relieve pain. If the knee is swollen due to an injury or condition, the pressure of the fluid build-up can cause intense pain and discomfort. By draining the knee, the pressure is released and the pain is alleviated. It can also help reduce inflammation and improve knee mobility, making it easier to move around and participate in everyday activities.

Cons – The List

1. Knee draining is an invasive procedure that could be a portal of entry for infection-causing bacteria. Additionally, the procedure can cause some pain and discomfort. The patient may experience bruising, swelling and redness at the drainage site. There is also the risk of developing a hematoma, where the blood vessels are damaged and blood pools in the area. In very rare cases, the knee may become infected, which can lead to complications if not treated promptly.

2. One of the pros of draining knee fluid is the decrease in fluid buildup. When too much fluid builds up in the knee joint, it can restrict movement and cause pain, swelling, and a limited range of motion. By draining the fluid, you can reduce these symptoms and improve your overall mobility. Additionally, draining the fluid can help reduce the risk of infection and inflammation. While not all fluid buildup requires draining, if it is causing significant pain and discomfort, draining the fluid can be a helpful solution.

3. One of the risks of draining the knee is infection. This is because the procedure involves making an incision, which can create a pathway for bacteria to enter the body. Patients should be aware of the risk and take extra precautions to reduce the chances of infection. For example, patients should keep the incision clean and dry and should avoid activities that put them at risk of further injuring the knee. Additionally, they should seek medical attention if they notice any signs of infection, such as redness, swelling, fever, or increased pain.

4. One of the potential downsides to draining the knee is that it can cause damage to the joint, if not done properly. The procedure requires inserting a needle into the joint and carefully removing the fluid. If the needle is inserted too deeply, it can damage the cartilage and ligaments in the joint, resulting in pain and instability. This can ultimately lead to irreversible damage and possibly long-term disability. It is important to have the procedure done by a qualified medical professional in order to reduce the risk of this kind of damage.

5. One of the potential risks of draining a knee is the risk of further injury. Depending on the severity of the condition being treated, the procedure may cause further damage to the knee and surrounding ligaments, tendons, and muscles. If the condition is related to a fracture or dislocation, the procedure could potentially worsen the injury if not done correctly. Additionally, the draining procedure could cause infection or excessive bleeding if not done properly. As such, it is important that the procedure is done by a skilled and experienced doctor.


It is important to weigh the pros and cons of draining the knee when a patient has a swollen knee due to injury or infection. It is a medical procedure that can provide relief from pain and discomfort. However, it should be done with caution and after consideration of the risks involved. Consulting a doctor before deciding to proceed with this procedure is essential to ensure safety and proper care.
