I had meniscus surgery 3 months ago and since then my knee has been drained twice 50 cc removed the fisrt time then a month later 40 cc's. After the second time 3 days later the swelling was back just as bad if not more. I can bend and I have pain when walking due to the sweeling. Any answer as to why this is happening would be appreciated. I'm also going to physical therapy3 times a week and ice it everyday.
