I am in the recovery of repairing a torn meniscus and removal of a Baker's cyst. I am very pleased with the surgery. If you don't take care of it, the tear can get caught and cause more issues. The surgeon just "shaved" off the tear.
Be prepared for bruising and lots of icing. Yes, the ice does feel wonderful. I was on pain pills for only 3 days. I did not find the post op too bad. That's what I can offer as my words of wisdom. Best of luck to you with your surgery.
