I had my scope yesterday to take a closer look at what was wrong. MRI showed nothing and luckily it was correct. It just needed to cleaned up and old bits of cartilage and ligament from previous surgery had to be cleaned out loads of fluid to. However he did say that somehow i have caused a divet/dent in my cartilage probably from a challenge or something during football. This had collected loads of old bits in it and was causing pain on the lateral side of the knee. I have just taken the bandages off curiosity got the better of me, and there quite a lot swelling mainly above the knee cap, is this normal? I did not have anything major done so i thought swelling would be minimal. Any advice on getting the swelling/fluid down dont wont it interfering again like last time. Thanks
