I had a right knee MRI as it was hurting. I have had tracking problems from time to time. I am 18 kegs overweight. I walk 5-7kms per day. I do yoga3x per week. MRI says- severe bone bruising and bleeding, micro fractures of tibia, 2 complex menus all tears-anterior and posterior, grade2-3 cartilage thinning, fluid above knee and in knee behind patella, bathers cyst, ligament strain, some bone growth and early osteoarthritis. What the hell do I do- I am thinking lose weight, swim, take chondritin, glucosamine, vitamin c, see a knee surgeon... what I DONt want is a knee replacement. It is a bit stiff, swollen and aches.
