Hello daniel. I am going to give you some choices. I am assuming that your MRI was done for knee pain. Your MRI shows arthritic changes in your knee and surrounding soft tissue. Your choices involve: 1. do nothing. Of course this option assumes that you can continue your current activities without causing pain. 2. physical therapy will increase the strength of the muscles around your knee but will not change the arthritic changes already present in your knee. 3. change exercise routine to choose exercises that are considered low impact. This will not change the current arthritic changes in the knee but should decrease pain and will help slow the progression of the arthritic changes. If you do a lot of running/walking on treadmills, consider a stationary bike. 4. steroid injections will help the pain and movement of the knee but will not deal with the arthritic changes in the knee. 5. Hyaluronic acid injections which will help re-build the cartilage in the knee. Hyaluronic acid is made from rooster combs. 6. arthroscopy which is laproscopy of the knee will deal with the arthritic changes in your knee but this is temporary. 7. Knee replacement--last resort when knee pain becomes severe or are having severe knee issues, such as locking of the knee, to the point where the knee is almost unusuable. At your age, having a knee replacement now means that sometime in the future you will probably have to have a second knee replacement. Replacement knees are not as good as the original and you will not be able to do certain activites such as kneeling. Studies have shown that some people can get relief from knee pain by using glucosamine/chondroitin. Be well, Dr.Kimberly
