Lower leg stiffness persisting several months after arthroscopic knee surgery?

Baker's cyst: It may be or may not be related to the arthroscopic surgery. I would consider a baker's cyst with fluid leaking down from the knee as a possibility. Would also consider other vascular, neurologic, bone or joint consideration. If the reason for the arthroscopy was in the arthritis maybe there's arthritis in the ankle midfoot or hind foot.
