After the injected MRI we figured out that since my knees endured so much "abuse" even after they became injured. The swelling began to spread from the point of origin to all along my patellar tendon. and in this process my body tried to kill off what ever was inflamming my tendon; by doing that, my body cut all blood supply to my tendon area. which was the reason that it wasn't healing properly. Basically my body was trying to detatch my patellar tendon from my knee to keep  the inflammation from spreading.
