Why Does the Knee Swell?
Your knee is the support system which allows you to walk, run, and sit. Inside of knee, there arebones, cushions (cartilage), strong ropes (ligaments), and a little fluid to keep things smooth.
And when anything goes wrong, the knee can become damaged or sprained, resulting in swelling. Here are the most common reasons of knee problems:
1. Injuries (the most common cause)
Twists and tears: If you’ve experienced a sharp twist of your knee, you could damagethe ligaments or meniscus (soft cushion inside the knee). Swelling usually starts quickly.
Falls or accidents: This could cause fractures (broken bones), ligament or meniscal tears, and swelling.
2. Arthritis or Gout (wear and tear or inflammation)
Osteoarthritis: Withage, the knee joint slowly wears down, leading to swelling and stiffness.
Rheumatoid arthritis: It is a condition in which your own immune system attacks itself, leading to symptoms within the joints.
Gout: Uric acid builds up as tiny crystals inside the knee, causing sudden sharp pain and swelling.
3. Infections (need urgent care)
Sometimes, germs (bacteria) enter the knee joint which causes swelling, pain, redness, and often fever. You must see a doctor in this situation.
4. Other reasons
There can be some reasons for your swollen and painfulknee. Some of them are:
Bursitis: Small fluid sacs around the knee get inflamed.
Tendonitis: Overuse of the knee from running or jumping.
Blood clotting issues: Rarely, blood clots can develop in the knee and can cause swelling.
How Do Doctors Find the Reason?
Now, when you go and visit a knee doctor like Chinmay Gupte for your treatment of your swollen and painful knee, this is what a typical consultation looks like:
· Focused questions – The doctor will ask when your symptoms started, how painful your knee is, and any potential causes, such as falling or sporting injury.
· Examination – They look at the knee, press gently, and move it identify the most likely cause of the pain.
· Scans – X-rays or MRIs may be used to visualize the joint.
· Tests – Sometimes a blood test or a small sample of knee fluid is checked for infection or gout.
This helps find the real reason, because every swollen knee is not the same.
