Complications

By Mayo Clinic staff

Rarely, a Baker's cyst bursts and synovial fluid leaks into the calf region, causing sharp pain in the knee, swelling and sometimes redness of the calf. These signs and symptoms closely resemble those of a blood clot in your leg. If you have swelling and redness of your calf, you'll need prompt medical evaluation, because a blood clot may require urgent treatment.
