Some symptoms of a ruptured Baker's cyst include swelling, pain, and bruising of the knee, as stated by MedlinePlus. The symptoms tend to mirror those of a blood clot in a vein. A person must seek medical attention to rule out the presence of other severe conditions.
A Baker's cyst is a buildup of synovial or joint fluid that develops a cyst behind the knee, notes MedlinePlus. This condition is caused by a swelling in the knee. It can accompany knee arthritis, a tear in the meniscal cartilage or rheumatoid arthritis. The cyst feels like a water-filled balloon and it rarely bursts. When it ruptures, the fluid is absorbed into the body, as stated by the Cleveland Clinic. Often the cyst reappears after it bursts. A person needs to seek treatment to prevent the recurring of a Baker's cyst.
Treatment of a cyst involves nonsurgical options such as resting the leg, draining the cyst, applying ice, taking anti-inflammatory medications, getting a steroid injection and having a physical therapy. If the cyst fails to heal, a doctor may recommend surgery, which involves making a cut in the knee. A surgical procedure is likely to work if the initial cause of a Baker's cyst was treated completely, reports Cleveland Clinic.
