Written byBel Marra HealthPublished onSeptember 5, 2017

Hemarthrosis or articular bleeding is hemorrhaging inside joints, which can cause extreme swelling and pain. The knee is one of the most common areas affected by hemarthrosis, and if it goes untreated, it can lead to permanent damage. Here we take a look at what leads to bleeding in the knee joints and how it can be treated.

Other Causes Of A Swollen Knee

Usually, knee swelling remains inside the knee joint as the joint capsule acts like a barrier, preventing the fluid from escaping.

However, it can also occur outside the joint capsule, known as extra-articular swelling. The most common types of swelling outside the joint capsule are:

1. Knee Bursitis:Bursa are small fluid filled sacs that sit between bones and soft tissues to reduce friction. If there is excessive friction on them, they get inflamed. You tend to get pockets of swelling rather than general swelling of the whole knee.

Swelling in front of the knee cap of usually caused by Pre-Patellar Bursitis, aka Housemaids Knee.Swelling behind the knee, often like a squashy orange, is usually due to Popliteal Bursitis, aka Bakers Cyst. Swelling on the inner side of the knee may be due to Pes Anserine Bursitis. Visit the Bursitissection to find out more, including treatment information.

2. Haematoma: Blunt trauma to the soft tissues around the knee can cause bleeding. The blood collects around the muscles and can build up into a hard lump. If there is only a small amount of bleeding it is usually referred to as a contusion/bruise.

Fluid aspiration may be performed if swelling above the knee is severe and not infected. It gives relief in pain following reduction in size of knee swelling. The fluid after aspiration is sent for lab studies and used as a diagnostic tool to detect the exact cause of inflammation. Depending on the fluid examination, further treatment may be planned. Knee joint infections is treated with antibiotics and anti-inflammatory medications. Autoimmune disease and joint inflammation is treated with corticosteroid treatment.
