I think I tore my meniscus (not sure which) in the left knee; firstly about four months ago, it s stayed sore for a short while then got better with a little soreness here and there. Secondly, one month ago my left knee popped out of place during a sport activity and has been randomly feeling of set when in squatting position to standing position then replaced with a little adjustment. Today it is now filling with fluid and hard to walk on. Will thus go away or do I need surgery?
Dear patient First we have to confirm the diagnosis.  Are you having symptoms of locking and inability to put weight on left knee? If yes there is possibility of meniscus tear. You have to go for MRI of left knee to look for exact site, type and which meniscus is torn.  Visit radiology center nearby you and get it done.  Tears which requires surgery are 1. Bucket handle tear 2. Complex tear 3. Anterior or posterior horn teat with instability.  You need to consult expert arthroscopic surgeon nearby you with report and get yourself examined.  All the best.
