Hi, sorry to hear about the fracture. Was it displaced and needing surgery? Patella fractures take an awfully long time to heal. When I broke mine in November, all the advice I got was to be patient. Everyone's story with this break is different. Have you been put in a fixed brace, if so for how long? My fracture was comminuted and now just over 3 months later, I am walking (without aids or a brace), albeit slowly, with the feeling that my leg doesn't really belong to my body! One of the main problems with this fracture is the Quad muscle loses all its tension and strength and I think this will take months and months and may never be the same as the other leg. I still get some pain, especially at night and have to take medication. I am doing physio every day (homework), only see the physio once a week. I also go to hydrotherapy 3 times a week, I think this has really helped and if you can get to a hydrotherapy pool, I really would recommend it. When I have been exercising and the knee starts to swell and hurt, I use a cryocuff system, brilliant.
Good luck and be patient and try not to do too much too soon.
