Causes And Risk Factors Of A Baker's Cyst

Torn Meniscus

Rotating the knee while it is in use can result in the tearing of one of the pieces of cartilage that cushion your leg bones where they meet at the knee. It more commonly occurs while playing certain sports, such as basketball, soccer, or football, though it can occur during any activity. A torn meniscus can result in pain, swelling, and a reduced range of motion in the knee. The swelling can lead to an increase in synovial fluid as the body attempts to protect the joint. Thus, a Baker's cyst can form. Even after your knee has healed following a tear in the meniscus, the injury can lead to osteoarthritis, another risk factor to Baker's cysts.
