question: I have been diagnosed with Patellar Subluxation in both knees which essentially means my knee caps pop in and out of place. I am 28 years old and has been occurring since I was 7 years old. I was told my plates in my knees were far apart and would outgrow this by the age of 18 (which has not been the case). My latest x rays show a floating mass in my left knee (most likely cartilage). That knee now makes a popping sounds (no pain but feels uncomfortable) when i straighten it after being bent for a period of time. Because of this disorder, I often get flashes of instances where my knee pops out, whence in pain even though nothing is happening and just fearful that it will happen again at any given moment. I get very anxious every so often. Not every day but at least 1-2 times a week. Not sure if this a form of PTSD but looking to at least resolve the uneasiness of my situation. Any thoughts? Also, looking for an expert who handles Subluxation and Dislocation knee injuries.
