Baker's cyst indicates degenerative changes in knee.
It might cause a heavy feeling in the knee, poor cosmesis and pain occasionally.
Relatively simple option is to go for percutaneous or ultrasound guided needle decompression and intrarticular methyprednisolone injections.
Next Steps
Visit Orthopaedic Surgeon for clinical evaluation and decompression.
Health Tips
Performing knee quadriceps exercises is really helpful in management of knee osteoarthritis and recurrence of baker cyst post decompression.
