Complications of Baker's cyst
NHS ChoicesMedical Reference
Ruptured Baker's cyst
In rare cases, a Baker's cyst can rupture (burst), causing the synovial fluid to leak down into your calf. This can cause:
- a sharp pain in your knee and calf, and
- swelling and inflammation of your calf.
The synovial fluid will gradually be reabsorbed into the body over one to four weeks. Prescription painkillers, usually a combination of paracetamol and codeine, can be used to control any pain.
