Knee Swelling: Causes, Symptoms, Treatments & Prevention

Knee swelling, also called water on the knee, is a frequent disorder that results from various factors, including sudden injury and chronic illness. For effective management and rehabilitation, it is important to know what causes it, its symptoms, and how best to treat it. This blog will walk you through all of this in detail.

Common Causes of Knee Swelling

Knee swelling can be triggered by several different factors, which includes:

• Injury: Injuries such as ligament tears, fractures, or meniscus tears can lead to fluid accumulation in or around the knee joint.
• Arthritis: Various forms of arthritis, including osteoarthritis and rheumatoid arthritis, are known for causing knee swelling due to inflammation.
• Bursitis: Inflammation of the bursae, small fluid-filled sacs near the knee joint, often results in swelling.
• Infections: Infections within the knee joint (septic arthritis) can lead to significant knee swelling and pain.
• Overuse: Repeated stress or overuse can cause swelling from irritation and inflammation of the knee joint and surrounding structures.

Symptoms of Swollen Knee

Identifying the symptoms of swollen knee early can help in managing the condition effectively. Some symptoms to look out for are:

• Visible Swelling: The knee appears larger than normal or asymmetrical compared to the other knee.
• Pain: Swelling often comes with pain during movement or even at rest.
• Stiffness: The knee may feel stiff, making it difficult to bend or straighten fully.
• Redness and Warmth: The knee might be warm to the touch and red, especially if infection or inflammation is involved.
• Decreased Mobility: Difficulty walking or bearing weight on the knee.

Diagnosing Knee Swelling

In order to get the most effective knee swelling treatment, an accurate diagnosis is the first step. The following diagnostic procedure is the most suitable:

• Medical History: Discussion of any recent injuries, activities or health changes.
• Physical Examination: The doctor would be checking for pain points, range of motion and fluid accumulation.
• Imaging Tests: X-rays, MRIs or CT scans are used as visual aids to understand the internal structures of the knee.
• Blood Tests: To detect infections or markers of inflammation.
• Joint Aspiration: Removing fluid from the knee joint for analysis to determine the cause of the swelling.

Treatment Options for Knee Swelling

Treatment depends on the underlying cause but generally includes:

1. Medication

Anti-inflammatories and painkillers to reduce pain and inflammation.

2. Physical Therapy

Exercises to strengthen the muscles around the knee and improve mobility.

3. Compression

This can be done through knee wraps or braces whose major aim is getting support as well as reducing swelling experienced in these parts.

4. Elevation

Keeping the knee elevated to decrease swelling.

5. Surgery

In severe cases, it may be necessary if other treatments fail or if there is severe damage to the knee.

Home Remedies and Self-Care Tips

Some effective home management strategies include:

• Ice Therapy: Apply ice packs to the knee for 20 minutes every few hours to reduce swelling.
• Rest: Avoid activities that strain the knee further.
• Elevation: Elevate the knee above the level of your heart to help reduce swelling.
• Compression: Use an elastic bandage or a knee sleeve to help control swelling.

Impact of Knee Swelling on Daily Activities

Swollen knees can significantly impact daily activities by:

• Limiting Mobility: Difficulty in walking, climbing stairs, or performing normal movements.
• Pain Management: Chronic discomfort can affect overall quality of life.
• Activity Restriction: Need to modify or limit activities to avoid exacerbating the condition.

What are some common tests for diagnosing the cause of knee swelling?

Testing typically involves X-rays, MRI scans, blood tests and joint aspiration, which involves extracting fluid from a swollen knee to analyse it for signs of infection or diseases.

What are some quick ways to reduce knee swelling at home?
