Cyst can cause pain: A bone cyst in the distal femur is a common finding on x-ray of the knee. It is possible that the cyst can cause pain and a small effusion. The next step is to see a medical provider and have an MRI performed on the knee including the distal femur to evaluate the cyst and knee joint in more detail.
