A few years ago, I fell playing football and I've "destroyed" some ligaments on my right knee. Last Year, on that knwee I discover a little ball inside, after a ecography, the doctor find out a cyst, probably from a traumatism in this knee. Until here everything is ok, but, last month, I discovered more 3 new "balls" inside my left knee, the "fine" knee. They are similar to the cyst in my right knee, so everything point to be exactly the same. I would like to know, more information about what are this cyst and what causes them. They don't cause pain to me, I reall don't fell them usually, i only fell them, when i touch in my knees or when i put knees on the floor.
Cysts around the knee have multiple causes including irritated and inflamed bursae, meniscal cysts, Baker’s cyst or popliteal cyst, ganglia (both intra-articular and extra-articular), vascular masses, and extraneural cysts.
One of the most common knee cysts is the popliteal cyst, otherwise known as a Baker cyst; its symptoms can include pain. Large popliteal cysts can rupture and become quite painful; it is important to rule out deep vein thrombosis in these instances. Meniscal cysts cause pain that is often associated with a palpable, firm mass.
Most often in adults the Baker's cyst is found in conditions where there is chronic swelling or fluid accumulation in the knee joint. These conditions include knee arthritis, meniscus injuries, and ligamentous injuries.
MRI , Computed tomography (CT) scanning, knee arthrography, and bone scanning are some of the investigations used for the diagnosis.
Treatment includes anti-inflammatory medications and cortisone injections. In some patients, placing a needle directly into the Baker's Cyst to drain the fluid can be helpful.
