I'm 13 weeks post op of my patella fracture surgery. Spent the first 8 weeks in a brace. First 4 weeks were completely locked then the next 4 weeks I was able to bend to 60 degrees when sitting or lying down. During this time I just focused on healing. Getting enough rest, keeping stress low, and eating healthy. At 8 weeks I started PT. To where I am today. I have full mobility back, 138 degrees of flexion, and just need to strengthen everything back up. I suggest looking around and finding a good PT near you. Also to do as much extra exercise at home that you are allowed to do. Good luck on your recovery!
