I had CKR on my left knee 2 years ago. I have had a LARGE swollen knee and a burning sensation in the knee & lower leg ever since, It is more intense at night and starts shortly after I lie down. I have not found a comfortable position for the leg to alleviate this. My F/U visits were all with a PA ... He says swelling is normal after surgery (2 yrs after ?) ... put an ice pack on it an hour before bed time ... (?) Most of the time I can tolerate the discomfort but it does keep me awake several times a month ... Tylenol doesn't help with "burning". NOW ... ( a month ago) a HUGE knot appeared on the outer side of the knee ... there was only minor pain at first ... after a few days I went to the Ortho clinic ... 1st visit = it is a pocket of fluid - given a script for a "Z" pack steroid - return in one week ... 2nd visit, knot was larger and pain was increasing, PA drew out a tube of liquid for a lab test-return in 1 week ... 3rd visit (10 days ago) knot is really huge (some where between a golf ball and a baseball) now and pain now requires Tylenol ... PA says it is a ganglion cyst. I was asked if I want it removed (DUH). My affected knee is twice as big as the other one. DISCUSSION: Is excessive swelling "normal" after two yrs? Is there any correlation between surgery and developing a cyst? Scheduled to have cyst removed in 2 weeks...Thanks
