In have pain in my elbow. In did not injure it in any way however , I had an operation over a year ago on my knee. I fell and broke the patella bone , was operated on, had PT and now I have arthritis in my knee that gives me little pain but causes stiffness. Does the arthritis in my knee have anything to do with my new elbow problem? I am seeing a specialist on Tuesday of next week. Thank you. AK
