I am a 58 year old female long distance runner. I the past 7 months I've had Supartz injections, then scope surgery on my right knee. My meniscus was torn in half and could not be repaired so most of it was removed. I have too much cartridge loss in the anterior portion of my knee and arthritis that no repair can be done with that either. I am totally unable to run anymore and cannot even walk around the grocery store without pain. I've been in PT three days a week since November 30, 2010. Now I've been sent to a pain management doctor who gave me a TENs unit and set me up with an acupuncturist . My ortho said that if all this did not help to come back and talk about partial knee replacement or knee realignment surgery. I sure don't want to do surgery but I can't stay the way I am now either. More than anything I want to be able to run again. It does no good to tell me I can do other sports, I am seriously mourning for the loss of my running. I have 24 full marathons to my credit (26.2 miles), and if I could only run one marathon per year I'd be happy and would happily do daily runs on soft dirt and grass if need be and cross train on a bike. If I have surgery I sure would like to know if any running would still be in my future. Partial replacement...full replacement?? Does anyone have any info that can help me?
