Swollen knee causes

Swollen knee causes

The most common cause of a swollen knee is when too much fluid gathers in or around the knee joint.

To some people it is called fluid or water on the knee, the medical term for the condition is effusion of the knee joint.

Other swollen knee causes could be a result of knee trauma (bang on the knee) overuse of the injured knee or perhaps an underlying condition or disease.

Your doctor will determine the primary cause and recommend an appropriate treatment, some of the fluid may be removed to help with reducing the stiffness and pain linked to the swelling.

Symptoms of swollen knee

The signs & symptoms of swollen knee are:

  • Swelling: The area surrounding the kneecap can noticeably puff up, the affected knee looks much bigger than the other knee
  • Pain: The cause of the swelling will have a direct bearing on how painful the skin area around the knee is, in certain cases it will be very difficult to put any weight on the leg.
  • Stiffness: The excess fluid around the kneecap will make it hard to bend or straighten the leg fully

When should you go to see a Doctor?

If you have tried taking over the counter painkillers but the swelling and pain isn’t going away or if one knee feels warm to touch or it may be red. You may also have tried using an ice pack to no avail.

 Swollen Knee Causes

  • ACL or anterior cruciate injury occurs when the ACL is stretched, partly torn or fully torn. The most common type of ACL is a complete tear, the symptoms consist of pain, unstable knee, and joint swelling.
  • Torn meniscus

This is one of the most common types of knee injuries, a torn meniscus can happen if you put some force behind your knee when you twist or rotate it, this is quite common with sports activities like soccer or football.

The menisci are cartilage shaped like a C that are found in your knees, they form a cushion between the shinbone and the thigh bone. Should the meniscus become torn it will lead to swelling, pain and stiffness, it may also cause trouble when trying to extend the knee out.

Symptoms of a torn meniscus include;

  • Swelling or stiffness
  • A feeling that the knee has popped out
  • Sharp pain when twisting or turning
  • Difficulty when trying to straighten the knee fully
  • The knee feels locked at times

  1. Hi Fintan, I must say that this article is very helpful and informative. A swollen knees is very common today and not so many people actually know to cure that. My dad has the same problem and I would never remember turmeric. I hear about its benefits but I did not know that it is good for swollen knees. I will definitely recommend it to my dad.

  2. This is helpful information on swollen knee issues and taking Curcumin to alleviate the pain and swelling.  My husband has RA, and frequently has swollen joints, and his doctor recommended a similar anti-inflammatory supplement similar to Curcumin.  I’m glad you recommend at the beginning to visit with your doctor about a swollen knee.  Thank you again for the info.  Rhonda
