Hello, I fractured my left patella 8 days ago June 26 2014. It was not caused by a fall. It happened while trail running and rolled my right ankle (not unusual) and caught it quickly. As I caught it, I had my left foot planted on unstable area and I heard crack in my left knee. Received x-ray few hours later with knee immobilizer and crutches. Got into ortho next day for quick exam and he referred for MRI. I m pretty sure he said it s non-displaced. I feel kind of in the dark because not much was told to me about treatment plan. I hope to get in to see ortho this week since they ll have MRI info. I didn t receive patient education other than when I asked about going to the gym that weekend for upper body exercises, I was told to rest and no weight bearing . I m very healthy active 56 yr old female - lots of trails to run and peaks to hike! (5 ft 3 in and 105 pounds) I appreciate any thoughts you can share regarding restrictions, possible causes, expectations regarding treatment, recovery, and future running/hiking. Thank you so much!
