What's it like to have a swollen knee?

When the knee is swollen, it means that there is an abnormal accumulation of fluid in the knee joint, usually due to inflammation or injury. This accumulation of fluid can cause the affected knee to feel swollen, stiff and sometimes painful. In addition to physical discomfort, swelling can limit the knee's mobility and range of movement. It is important to consult a healthcare professional to determine the cause of the swelling and receive appropriate treatment.

Common causes of knee swelling

Knee swelling can result from a variety of causes, from sports-related injuries to more complex inflammatory conditions, but that doesn't mean the cause is serious. To find the right remedy, it's essential that you identify the cause first.


Sport-related injuries

Sports activities, although essential for good health, can sometimes lead to knee injuries that can cause swelling. Several mechanisms are regularly implicated in this swelling, including:

Ligament and tendon causes:

  • Collateral ligament sprain: Excessive stretching of this ligament can cause inflammation.

  • Tendonitis: Inflammation of the tendons, often due to overuse, can also cause swelling, which will subside slightly after exertion.

Traumatic causes:

  • Fractures: Fractures of the knee, whether of the femur, tibia or patella, are major traumas that can cause immediate and significant swelling. They can result from serious accidents, falls or traumatic collisions, which cause swelling in response to the release of fluids and inflammatory cells in the area.

Wear-related causes:

  • Patellofemoral syndrome or "runner's knee": Patellofemoral syndrome, also known as "runner's knee", is a condition resulting from wear to the cartilage behind the kneecap. This wear can be caused by a variety of factors, including poor joint mechanics, muscle imbalance, overuse or incorrect positioning of the kneecap.



Arthritis and inflammation

Arthritis is an inflammation of the joints that can also cause swelling in the knee. The two most common types of arthritis are:

Osteoarthritis:

  • Wear and tear of the cartilage: Osteoarthritis is a degenerative joint disease that results from the progressive wear and tear of the cartilage. Cartilage normally acts as a cushion between the bones, ensuring smooth, friction-free movement. But with osteoarthritis, the cartilage loses its thickness and elasticity, leading to increased pressure on the bones and hence inflammation of the joint.

Rheumatoid arthritis:

  • Autoimmune response: Rheumatoid arthritis is an autoimmune disease in which the immune system, through an abnormal reaction, attacks the synovial membranes that surround the joints, causing inflammation and swelling.



Other factors, such as being overweight

Being overweight puts extra pressure on the joints, particularly the knees, on which much of the body's weight rests. This can contribute to the development of various problems, such as:

Excess weight:

  • Increased wear and tear: Cartilage, which normally acts as a shock absorber between bones, can wear down prematurely as a result of this constant pressure. Cartilage wear triggers an inflammatory response to compensate for the damage, which can lead to knee swelling.

Mechanical factors:

  • Muscle imbalance: The muscles that support the knee joint may become weaker or tighter as a result of overweight, affecting knee stability. This muscle imbalance can overload the joints, increasing inflammation and swelling in the knee.

Systemic inflammation:

  • Generalised inflammatory response: Being overweight is often associated with systemic inflammation, which can also affect the knees. Excess body fat, particularly in the abdominal area, releases inflammatory substances into the bloodstream, reaching the joints and exacerbating inflammation in the knee.

Swollen knees: what are the associated symptoms?

  • Sensation of swelling or distension in the knee.

  • Joint stiffness, particularly after a period of inactivity.

  • Pain, which can range from mild to intense, depending on the cause of the swelling.

  • Difficulty bending or fully extending the knee.

  • Redness or warmth to the touch around the affected joint.

  • Sensation of cracking or creaking when moving the knee.

  • Reduced mobility and ability to bear weight on the affected knee.

These symptoms may vary depending on the underlying cause of the swelling, which may be due to injury, inflammatory disorders, infection or other medical problems. It is advisable to consult a healthcare professional if you experience persistent symptoms or if the knee swelling worsens.

What illness causes swollen knees?

While knee swelling is mainly linked to a mechanical problem caused by over-use of the joints, it may also be due to certain medical conditions. Here are some common conditions that can cause swollen knees:

Osteoarthritis: Osteoarthritis is a degenerative joint disease that leads to the progressive breakdown of cartilage. This process can lead to inflammation of the knee joint, also causing swelling. People with osteoarthritis often experience joint pain, stiffness and reduced mobility, often linked to age.

Rheumatoid arthritis: Rheumatoid arthritis is an autoimmune disease in which the immune system attacks the synovial membranes of the joints (what surrounds the fluid in the knee and helps with mobility). This leads to persistent inflammation and swelling in the knee. As well as swelling, rheumatoid arthritis can also cause widespread fatigue, stiffness in the morning and progressive deformity of the joints.

Gout: Gout is a type of arthritis caused by the accumulation of uric acid crystals in the joints. When crystals form in the knee, this can trigger an inflammatory reaction that leads to sudden and very painful swelling. Gout attacks can be triggered by excessive consumption of purine-rich foods.

Bursitis: Bursitis of the knee occurs when the synovial bursae, the famous little fluid-filled pockets that reduce friction between tendons and bones, become inflamed. This inflammation can lead to painful swelling around the knee. Injuries, infections or repetitive movements can encourage the development of bursitis.

Autoimmune diseases: Certain autoimmune diseases, such as lupus, can affect the joints and cause swelling. This disease involves an abnormal immune response that attacks the body's tissues, including the joints, leading to inflammation and swelling.

Infections: Joint infections, although rare, can also be responsible for swollen knees. Bacteria or viral pathogens can infect the joint and trigger an inflammatory response.


Can you walk with synovial effusion?

It is generally possible to walk with synovial effusion, but it is important to remain cautious and to seek your doctor's prior agreement. Here are a few tips to help you remain independent without further damaging your knee:

  • Use a cane if necessary: If the pain is too great, you can use a cane on the opposite side to reduce and relieve the pressure on the affected knee.

  • Choose comfortable shoes: Shoes that offer good support can help minimise the impact on the knee joint when walking. Forget soles that are too flat, and opt for shoes with good support and plenty of bounce to prevent your foot from suffering.

  • Avoid uneven ground: Choose flat surfaces to reduce stress on the knee. Avoid uneven, stony ground, which could aggravate the situation.

If the pain persists or worsens, it is important to consult a healthcare professional so that your treatment can be adapted and you can receive advice tailored to your situation. Caution and adapting your activities to suit your comfort are essential if you wish to continue walking with a synovial effusion.

Understanding the knee and its anatomy

The knee is a complex joint that plays an essential role in mobility, supporting a large part of the body. Understanding its anatomy is essential to understanding the mechanisms involved in swelling in this joint.


Anatomy of the knee

The knee is a synovial joint made up of several interdependent structures. It is formed when three major bones meet: the femur (thigh), the tibia (leg) and the patella (kneecap). These bones are held in place by a complex network of ligaments, tendons and cartilage.

Main structures of the knee:

  1. Ligaments: The medial collateral ligament and the lateral collateral ligament stabilise the knee on its sides. The anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) contribute to anterior and posterior stability.

  2. The menisci: Two small cartilage discs, known as menisci, act as shock absorbers and facilitate fluid movement between the femur and tibia.

  3. The synovial membrane: A thin membrane called the synovial membrane lines the inside of the joint and produces a synovial fluid that lubricates and nourishes the cartilage.

  4. Articular cartilage: Cartilage covers the ends of the bones, providing a smooth surface to minimise friction and absorb shock.



Structures involved in swelling

Knee swelling can result from a variety of causes, often involving irritation or inflammation of key structures. The main structures to question in the event of pain are:

  1. The synovial sac: The knee has a synovial sac, a sac filled with synovial fluid, which can become inflamed in response to injury or overuse.

  2. Bursae: Bursae, small fluid-filled pockets, are found around the knee to reduce friction between the tendons and bones. Inflammation of these bursae can lead to swelling.

  3. Cartilage and menisci: Damage to the articular cartilage or menisci can provoke an inflammatory response, leading to swelling.

By understanding the anatomy of the knee and the structures involved in swelling, you'll find it easier to understand where your pain and related swelling are coming from.

How can I get my knee swelling and synovial effusion to subside as quickly as possible? Traditional remedies

Swelling of the knee, often accompanied by synovial effusion, can be particularly painful. Although traditional remedies are no substitute for a medical consultation, they can nonetheless provide relief. Here are a few tips on how to get your knee swelling to subside quickly and, above all, naturally.

Herbal cold compresses: Herbal cold compresses are a well-known traditional remedy for reducing inflammation. Use plants with anti-inflammatory properties such as Chamomile, Peppermint or Calendula. Infuse these plants in hot water, leave to cool and apply the compress to the swollen knee for 15 to 20 minutes, repeating several times a day.

Clay poultices: Clay is renowned for its anti-inflammatory and absorbent properties. Prepare a poultice by mixing clay with water to form a paste. Apply this paste to the knee, cover with a compress and leave on for about 30 minutes. Make sure you don't let the clay dry out completely to prevent excessive dehydration of the skin. Don't forget to moisturise your knee after applying the poultice.

Anti-inflammatory infusions and decoctions: Certain plants can help reduce inflammation by acting internally. Make infusions or decoctions from plants such as ginger or nettle. These drinks can be drunk several times a day to help reduce inflammation from the inside out. You can even add a teaspoon of honey for comfort and relief.

Rest and elevation of the knee: A very simple, but also very effective, solution is to give your swollen knee a rest. Avoid activities that could aggravate the inflammation for a significant period of time. To maximise recovery, elevate the knee every time you sit or lie down. This will reduce pressure on the joint and promote fluid drainage.

Anti-inflammatory diet: Eat a diet rich in anti-inflammatory foods such as oily fish (rich in omega-3), fruit and green vegetables, as well as nuts and seeds. These foods will help to reduce inflammation throughout the body, including in the knee.

My knee hurts when I bend and unbend it: what can I do?

Pain in the knee when flexing or extending can be a sign of inflammation, overuse or injury, such as tendonitis or cartilage damage (chondropathy). To relieve discomfort:

  • Apply cold to reduce inflammation if the pain is recent.

  • Rest your knee and avoid activities that put strain on the joint.

  • Try a natural solution, such as a green clay poultice or gentle massage with arnica or St John's wort macerated oil.

If the pain persists or worsens, consult a healthcare professional for an accurate diagnosis.

My knee creaks: what does that mean?

A knee that makes crackling noises is often due to friction between tissues or bones in the joint. These noises can be benign, especially if there is no pain, and occur due to a temporary lack of lubrication in the knee or staying in a prolonged posture. However, if the cracking is accompanied by pain or swelling, it could indicate:

  • Wear and tear of the cartilage (osteoarthritis).

  • Joint overload due to intense exertion.

To alleviate these problems, remember to strengthen your muscles with gentle exercise, keep well hydrated, and consider massaging with nourishing and soothing oils such as calophylla or wintergreen. If in doubt, seek medical advice.
