Why do i have a swollen knee?

You woke up this morning feeling stiff and creaky. After hobbling down the stairs like an old person, you took a look at your knee and noticed that it was twice the size of its usual self. Panic sets in as you realize that you have no idea why your knee is swollen. Fear not, my friend! In this article, we will delve into the reasons for swollen knees.

What is a Swollen Knee?

Before we get too deep, let’s start with some basics – what exactly causes swelling in the first place? Essentially, when there’s inflammation happening somewhere in your body (like inside your knee), fluid rushes to the area causing the tissue to swell.

Causes of Swollen Knees

There are many reasons why your knees may be puffy:


Arthritis is one of those conditions that can affect any joint in the body – but it loves hanging out in the knees. Rheumatoid arthritis (a chronic autoimmune disease) or osteoarthritis (a wear-and-tear degenerative condition).


Gout is another pesky condition known for setting up shop in our lower extremities; specifically our big toe joints but can also affect other areas such as ankles & knees . It appears due to excess uric acid crystals deposited simply put around certain nerves on specific small joints which cause more changes besides pain.

Meniscus Tear

If you’ve ever done anything athletic or just happened to bend over wrong while picking something up (we’re not judging) , then chances are you’ve heard about meniscus tears before.. This tear happens when one of those little shock-absorbing pads gets torn out from underneath either by trauma or regular usage .


When bursae become inflamed/irritated around all sorts of key areas such as kneecaps or achilles tendons, there is a possibility that you could be suffering from bursitis. Besides using compression bandages and ice packs when dealing with swelling from this condition to reduce swelling on the knee can help alleviate some of your discomfort..

Baker’s Cyst

The mysterious-sounding baker’s cyst (also called a popliteal cyst). This pocket of fluid-filled sacs seems to appear out of nowhere behind the knee cap in order to haunt us – almost like its own entity. It occurs most often for those who have arthritis but it also appears when one has suffered an injury .

Osgood-Schlatter Disease

This funny sounding name can actually cause quite a bit of pain if left untreated; likely is due to rapid growth spurts during early adolescent years before bones are fully formed causing small fractures at point where tendon attaches inside your knee throughout time.

There are other reasons why knees get swollen too many too list here (but don’t worry, we’ve got you covered).


As mentioned earlier, joint inflammation causes extra fluid build-up leading which leads then finally results in puffiness and stiffness . Swollen knees may change color & temperature compared such as hot-red while tenderness or darkness around affected areas similarly occur.

It could cause possible exacerbation .


Keep it elevated when possible by propping pillows under such joint otherwise use crutches…useless but still better than limping everywhere! Keeping legs straight during elevation blocks blood flow so be sure to keep them bent slightly.
