Can knee joint inflammation cause swelling?

Hello, Doctor: May I ask if inflammation of the knee joint can cause swelling and fluid accumulation? Will taking anti-inflammatory medications (NSAIDs) help reduce the swelling, or do they only address the symptoms without treating the underlying issue? I have a popping sound in my right knee when bending and straightening it, and the doctor suspects it may be due to plica movement causing inflammation (I am wondering if the lateral collateral ligament could be involved on the right side?).
Does a meniscus tear produce a sound? Is that possible? How should I manage this? I have an arthroscopy scheduled for next Monday, and I am worried that the procedure is similar to surgery and requires general anesthesia.
Will there be any complications after the surgery? How long does the surgery take? Could you please provide an overview of the arthroscopy procedure? Thank you! ^^

Hello: In response to your question...
The management of knee joint effusion involves compression with elastic bandages and the use of oral anti-inflammatory medications.
If the effusion does not resolve, joint aspiration is the next step, as it has two main benefits: first, it reduces the volume of the effusion, which can significantly alleviate symptoms; second, analyzing the color, composition, and viscosity of the aspirated fluid can aid in differential diagnosis.
For instance, a light yellow color is normal, while a deeper yellow with white particles may indicate gout.
If the fluid is bloody or deep red, it could suggest injury to the meniscus or ligaments.

A popping sound when bending and straightening the knee can have various causes, but as long as it is not accompanied by pain, there is generally no cause for concern.
Symptoms caused by a medial plica typically include pain during squatting, while meniscus tears usually present with pain, inability to bend the knee, or a sensation of locking.
Diagnosis can be confirmed through MRI or arthroscopy.

Arthroscopy can be performed under spinal anesthesia (epidural) or local anesthesia.
Generally, if it is just for diagnostic purposes, local anesthesia is sufficient; however, if treatment is needed, spinal anesthesia is more appropriate.
Arthroscopic surgery has several features: a tourniquet is applied to the thigh, the surgical images are displayed on a screen for the patient to see, and if convenient, the surgeon can explain the procedure to the patient in real-time.
Additionally, the surgery is recorded on VCD or DVD, and photographs are taken, which the surgeon can use to explain the condition post-operatively.
Arthroscopy is not a major surgery, and recovery is typically quick.
If you have any questions, please discuss them with your attending physician.

More Info

Knee inflammation can indeed lead to swelling, commonly referred to as "effusion" or "water on the knee." This condition occurs when excess fluid accumulates in or around the knee joint, often as a result of inflammation due to injury, arthritis, or other underlying conditions. The inflammation can be triggered by various factors, including overuse, trauma, or degenerative changes in the joint.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are often prescribed to help reduce inflammation and alleviate pain associated with knee swelling. While NSAIDs can be effective in managing symptoms and reducing swelling, they primarily address the symptoms rather than the underlying cause of the inflammation. Therefore, while they can provide relief, they do not necessarily "cure" the underlying issue. It's crucial to identify and treat the root cause of the inflammation to achieve long-term relief.

Regarding your specific concerns about the sounds you hear when bending or straightening your knee, such as popping or cracking noises, these can be caused by various factors. The presence of a plica, which is a fold of synovial membrane in the knee, can indeed lead to such sounds if it becomes inflamed or irritated. Additionally, a meniscal tear can also produce similar sounds, particularly if the tear is causing the meniscus to catch or move abnormally during knee motion.
As for your upcoming arthroscopy, it is a minimally invasive surgical procedure used to diagnose and treat various knee conditions. During the procedure, a small camera (arthroscope) is inserted into the knee joint through a small incision, allowing the surgeon to visualize the inside of the joint and perform necessary repairs. While general anesthesia is often used, some procedures can be done under local anesthesia with sedation, depending on the complexity of the surgery and the surgeon's preference.

Concerns about complications from arthroscopy are valid, but serious complications are relatively rare. Common risks include infection, blood clots, and damage to surrounding structures. However, the benefits of the procedure often outweigh these risks, especially if it can provide a definitive diagnosis and treatment for your knee issues.

The duration of the surgery can vary depending on the complexity of the findings and the procedures performed, but it typically lasts between 30 minutes to an hour. Post-operative recovery usually involves a period of rest, ice application, and gradual rehabilitation to restore strength and mobility to the knee.

In summary, knee inflammation can indeed cause swelling, and while NSAIDs can help manage symptoms, addressing the underlying cause is essential for long-term relief. The sounds you hear in your knee may be related to plica or meniscal issues, and arthroscopy can provide both diagnosis and treatment. It's important to discuss all your concerns with your orthopedic surgeon to ensure you are well-informed and comfortable with the upcoming procedure.
