Hi Thanks for writing your query After going through the brief description of yours. My advice would be do not go by the MRI report alone until and unless you have symptoms of disc prolapsed like sciatica pain in limb along with numbness and so on. Regarding knee it looks to be synovitis that is inflammation of membrane lining the joint, it needs physical examination. Meanwhile continue with ice fomentation, ibuprofen and trypsin to reduce pain and swelling. Hope this information helps you. If the problem persists see a doctor. Take care and I shall be glad to answer any further query. Regards Dr.chugh Orthopaedic surgeon http://bit.ly/drmchugh
