I have chondomalacia patella and once a year, my knee will swell to the size of a cantaloupe above my knee cap. At this point, it takes me about a month for swelling to go down before I can resume my normal activity once again. I have done as much as I can in terms of trying to strengthen, gain more flexibility at physiotherapy, ice, etc, but it always hits. I know when the swelling will happen to as it does swell right away, but takes about a week from the onset. Is there anything I can try to do to improve this problem?
