“Most often we see Baker’s cysts when a doctor has suspected a blood clot and orders an ultrasound,” says Tracy Ray, MD, a sports medicine specialist with Duke Orthopaedics. “The radiologist reads the scan and discovers a Baker’s cyst instead.” Treating the cyst is not important if there are no symptoms and they rarely cause further problems.” “Most of the time we tell patients not to worry about it,” he says.
In some cases, however, this accumulation of fluid can cause pain and stiffness. “If it’s causing pain, it’s most likely due to previous damage, such as arthritis, a torn meniscus, or other damage to the joint,” says Ray. “In these cases, we try to treat the initial injury or illness rather than focusing on the cyst itself.”
It’s not usually necessary to drain the cyst or to treat it with surgical methods, he notes. Baker’s cysts can usually be treated by resting the knee, applying ice packs, and taking NSAID pain relievers such as aspirin, ibuprofen or naproxen. If the pain is particularly bad your doctor may suggest cortisone injections to treat the underlying illness or injury.
As with most joint injuries, athletes are at higher risk of developing this cyst because of the strain they put on their knees. If you are doing a lot of exercise, you can protect yourself from a Baker’s cyst by wearing proper shoes when exercising, warming up and cooling down, and taking care to rest the knee if it is injured in any way.
